  With reference to FIG. 1, the travel information analysis system 301 includes three vehicles 11, a travel information processing server 12, an information storage device 13, an inquiry console 14, a signal control device 15, and an analysis device 101. . Note that the number of vehicles 11 is not limited to three and may be a plurality.

[Primary driving information]
The vehicle 11 is an automobile having a probe function, for example, and travels while repeatedly stopping and starting on a road on which another vehicle not having the probe function also travels. At this time, the vehicle 11 generates, for example, traveling data including its own position and the time corresponding to the position, in other words, traveling data including the own position and the time when the vehicle 11 was present at the position. .

  Specifically, the vehicle 11 can receive, for example, a radio wave transmitted from a GPS (Global Positioning System) satellite, and calculate vehicle coordinates indicating a position where the vehicle 11 is present based on the received radio wave. is there. Here, the vehicle coordinates include, for example, latitude and longitude indicating the position of the vehicle 11.

  For example, the vehicle 11 calculates the vehicle coordinates according to a predetermined sampling timing, and obtains the measurement time that is the time when the vehicle coordinate is calculated at the position indicated by the vehicle coordinates.

  That is, for example, the vehicle 11 generates travel data including vehicle coordinates and measurement time at each sampling timing. Here, the sampling timing may be, for example, every predetermined cycle, or every event such as stop, start, turn-on of blinker, elapse of a predetermined time from start and after traveling a predetermined distance from start. .

  For example, when the vehicle 11 generates travel data, the vehicle 11 generates primary travel information including the generated travel data and a vehicle ID that is its own identifier, and transmits the generated primary travel information to the travel information processing server 12. .

  For example, the vehicle 11 transmits primary travel information to the travel information processing server 12 using a wireless terminal device such as a mobile phone and a smart phone.

  Note that the vehicle 11 is not limited to a configuration that generates primary travel information at each sampling timing and transmits the generated primary travel information to the travel information processing server 12. For example, the vehicle 11 stores travel data for a predetermined period or a predetermined number. Thereafter, primary traveling information including each accumulated traveling data and vehicle ID may be generated and transmitted to the traveling information processing server 12.

  In addition, the vehicle 11 is not limited to a configuration that transmits primary travel information to the travel information processing server 12 using a wireless terminal device, but a configuration that transmits primary travel information to the travel information processing server 12 using an ITS radio. Or, when passing under an optical beacon provided above a road, the primary traveling information is transmitted to the traveling information processing server 12 by performing infrared communication with the optical beacon. There may be.

  With reference to FIG. 2, travel information processing server 12 receives primary travel information from a plurality of vehicles 11 and generates secondary travel information STI for each vehicle 11 based on the received primary travel information.

  Specifically, the travel information processing server 12 holds a digital road map database, for example. The digital road map database includes information about a subdivision map that is a subdivided map. A secondary mesh number that is an ID is assigned to the subdivision map.

  The digital road map database includes, for example, information about road links obtained by subdividing roads included in the subdivision map, and the information is associated with the secondary mesh number. The information about the road link includes, for example, node data that is information about the end portion of the road link and road link data that is information about the route of the road link.

  More specifically, the node data includes a node ID that is a node number, position information of the node, and the like. The road link data includes a road link ID that is a road link number, a length of the road link, position information of the road link, and the like.

  For example, when the travel information processing server 12 receives primary travel information from a certain vehicle 11 (hereinafter also referred to as a target vehicle 11), the target vehicle 11 is determined based on the received primary travel information and the digital road map database. Identify the road links that traveled.

  More specifically, for example, the travel information processing server 12 specifies a secondary mesh number based on vehicle coordinates included in the primary travel information of the target vehicle 11, and is included in the subdivision map indicated by the specified secondary mesh number. A road link (hereinafter also referred to as a travel link) on which the target vehicle 11 travels is specified from the road link.

  The traveling information processing server 12 specifies the traveling direction of the target vehicle 11 on the traveling link based on, for example, the time change of the vehicle coordinates included in the primary traveling information.

  For example, the travel information processing server 12 generates road link information including a road link ID of the travel link and a start node ID and an end node ID based on the identified travel direction.

  In addition, the travel information processing server 12, for example, based on the primary travel information, the link entry time that is the time when the target vehicle 11 enters the travel link and the travel time that is the time that the target vehicle 11 travels the travel link. Travel time information including is generated. Here, the time at which the target vehicle 11 exits the travel link, that is, the link exit time can be obtained by adding travel time to the link entry time.

  For example, when the target vehicle 11 stops at the travel link, the travel information processing server 12 generates vehicle stop information for each stop of the target vehicle 11. The vehicle stop information includes the stop start time, stop time, and stop position of the target vehicle 11.

  More specifically, the travel information processing server 12 generates vehicle stop information [0] when the target vehicle 11 stops once in the travel link, for example. Hereinafter, the array may be represented as * [idx]. * Idx in [idx] is an index of the array, and increases one by one in the order of time series when the target vehicle 11 stops.

  For example, when the target vehicle 11 stops twice on the travel link, the traveling information processing server 12 detects the vehicle stop information [0] and the vehicle stop information [1] corresponding to the first stop and the second stop, respectively. Is generated.

  For example, when the target vehicle 11 does not stop at the travel link, the travel information processing server 12 does not generate vehicle stop information.

  That is, the number of elements Ns of the vehicle stop information [0] to the vehicle stop information [Ns-1] represents the number of stops Ns of the target vehicle 11 in the travel link.

  Therefore, the secondary travel information STI is generated for each vehicle 11 and for each road link on which the vehicle 11 travels. The travel information processing server 12 transmits the generated secondary travel information STI to the analysis apparatus 101.

  The information storage device 13 stores traffic jam detection results for each vehicle sensor such as an ultrasonic vehicle sensor and an optical beacon in association with the detection time as traffic jam information. The traffic jam detection result is, for example, a value based on the magnitude relationship between the vehicle speed obtained from the detection result of the vehicle detector, that is, the vehicle speed, and the vehicle speed threshold value set for each vehicle detector.

  Specifically, the traffic jam detection result is information indicating, for example, “there is traffic jam” or “no traffic jam”. The vehicle speed threshold can be changed for each vehicle detector, for example.

  For example, when the information storage device 13 receives a traffic index information request from the analysis device 101 or the inquiry table 14, the information storage device 13 transmits the created traffic jam information to the analysis device 101 or the inquiry table 14 that is the request source.

  The signal control device 15 is, for example, a signal control system central device, and controls vehicle traffic signal lamps and pedestrian lamps at each intersection via lower devices according to signal control parameters including cycle length, split, and offset. To do.

  In addition, the signal control device 15 includes, for example, one or a plurality of sub-areas that are intersections where vehicle traffic signal lamps are provided and that include a plurality of intersections having the same control cycle length of the vehicle traffic signal lamps. It is possible to set and change the coupling state of the sub-areas.

  For example, when the signal control device 15 receives a signal control information request from the inquiry console 14, the signal control device 15 transmits the signal control information including the signal control parameter and the sub area combination information to the inquiry console 14.

  For example, when the signal control device 15 receives a signal setting change request from the inquiry table 14, the signal control device 15 changes the signal control parameter and the sub-area combination state according to the received signal setting change request.

  The inquiry table 14 is provided, for example, in a control center. Specifically, the inquiry console 14 is, for example, a PC (Personal Computer), and is connected to the information storage device 13, the signal control device 15, and the analysis device 101 through a network such as the Internet by wired or wireless communication.

  The inquiry console 14 includes, for example, a display device, and provides the user with the traffic information and the detector traffic information by displaying the traffic information and the sensor traffic information received from the information storage device 13 on the display device. To do.

  The inquiry console 14 provides the user with the signal control parameters and the subarea combination information by displaying the signal control parameters and the subarea combination information received from the signal control device 15 on the display device, for example.

  For example, when the inquiry console 14 transmits a signal setting change request to the signal control device 15 to change the coupling state of the sub-areas, the inquiry console 14 transmits sub-area change information indicating the change contents to the analysis device 101.

Here, the sub-area is an area that includes a plurality of same-period intersections that are intersections where vehicle traffic signal lamps are provided and that have the same control cycle length of the vehicle traffic signal lamps. In more detail, the memory | storage part 32 hold | maintains the subarea information containing ID of the same period intersection contained in a subarea, for example.

  For example, when the request processing unit 37 receives the subarea change information from the inquiry table 14, the request processing unit 37 updates the subarea information held in the storage unit 32 in accordance with the change content indicated by the received subarea change information.

  When the secondary travel information acquisition unit 31 receives the secondary travel information from the travel information processing server 12, the secondary travel information acquisition unit 31 accumulates the received secondary travel information in the storage unit 32. Note that the secondary travel information acquisition unit 31 may acquire the secondary travel information from a medium in which the secondary travel information is recorded, and accumulate the acquired secondary travel information in the storage unit 32.

  The preparation information creation unit 34 generates the preparation information PI for each vehicle ID, for example, based on the secondary traveling information STI for each vehicle ID and in chronological order. The preparation information PI includes information about an analysis link that is a link connecting the target intersections, that is, analysis link information.

  Specifically, the preparation information creation unit 34 acquires, for example, a start point node ID and an end point node ID from the secondary travel information STI.

  For example, the preparation information creation unit 34 refers to the digital road map database held by the storage unit 32 and acquires an intersection corresponding to the node indicated by the end point node ID from the digital road map database as an end point intersection.

  For example, when the position of the node indicated by the end point node ID and the position of the end point intersection substantially match, the node indicated by the end point node ID becomes the end point intersection.

  For example, the preparation information creation unit 34 refers to the digital road map database stored in the storage unit 32 and sets the intersection corresponding to the node indicated by the start node ID included in the road link information as the start intersection from the digital road map database. get.

  For example, when the position of the node indicated by the start point node ID and the position of the start point intersection substantially match, the node indicated by the start point node ID becomes the start point intersection.

  The preparation information creation unit 34 generates, for example, analysis link information including a start point intersection ID indicating the start point intersection and an end point intersection, and an end point intersection ID, and an analysis link ID indicating an analysis link connecting the start point intersection and the end point intersection. Therefore, the start point intersection and the end point intersection are target intersections.

  For example, the preparation information creation unit 34 generates the preparation information PI by replacing the road link information in the secondary travel information STI with the analysis link information, and stores the generated preparation information PI in the storage unit 32.

  For example, when the position of the node indicated by the end point node ID and the position of the end point intersection are greatly different, or when the position of the node indicated by the start point node ID and the position of the start point intersection are greatly different, the preparation information creation unit 34 The following processing is performed.

It correct | amends and the preparation information PI containing the travel time information and vehicle stop information after correction | amendment is produced | generated.

  For example, when the analysis link is included in the road link and the length of the analysis link is shorter than the length of the road link, the preparation information creation unit 34 travels based on the secondary travel information STI corresponding to the road link. The contents of the time information and the vehicle stop information are corrected, and preparation information PI including the corrected travel time information and the vehicle stop information is generated.

[Preparation array creation processing and link correspondence table creation processing]

  Specifically, the total period setting unit 36 sets a total period AUP [h] every 5 minutes, for example. Here, the index h is an integer. For example, the aggregation period AUP [h] is a period from 15:35 to just before 15:40. Similarly, the aggregation period AUP [h-1] is a period from 15:30 to just before 15:35. The same applies to the aggregation periods AUP [h-2] to AUP [h-4].

  That is, the aggregation period is advanced by 5 minutes as the index h is decreased by one, and is delayed by 5 minutes as the index h is increased by one.

  The aggregation period setting unit 36 outputs, for example, information about the set aggregation period AUP [h] (hereinafter also referred to as aggregation period information) to the probe data acquisition unit 35 and the request processing unit 37.

Similarly, the link correspondence table creation unit 46 also prepares the indexes j2s to j2e, j3s to j3e, and j4s of the preparation information for the inflow links IL (2, 0), IL (3, 0), and IL (4, 0). -J4e is specified respectively.

  Then, for example, as shown in FIG. 8, the link correspondence table creation unit 46 indexes the inflow links IL (1, 0), IL (2, 0), IL (3, 0), and IL (4, 0). A link correspondence table ILTbl [h] [k = 0] indicating each correspondence relationship with j1s to j1e, j2s to j2e, j3s to j3e, and j4s to j4e is created.

Therefore, as shown in FIG. 5, the link correspondence table holding unit 47 stores the link correspondence table ILTbl [h−s] respectively corresponding to the total period AUP [h−s] (s is an integer equal to or greater than zero). [K = 0] to ILTbl [h−s] [k = Ncs−1] are stored.

[Processing at the inquiry desk]
FIG. 22 is a diagram showing an example of a screen displayed on the display device in the inquiry desk according to the first embodiment of the present invention. FIG. 23 is a diagram showing an example of a screen displayed on the display device in the inquiry desk according to the first embodiment of the present invention.

  Referring to FIGS. 1, 10, 21, 22, and 23, when inquiry table 14 receives an analysis processing response, which is a response to an analysis processing request, from analysis device 101, for example, it performs the following processing.

  That is, for example, the inquiry console 14 generates a screen ImgSA obtained by superimposing the screen ImgAlys shown in FIG. 21 on the screen ImgMap1 shown in FIG. indicate.

  Further, for example, the inquiry table 14 displays the screen ImgLnk shown in FIG. 23 based on the display information IChtIn, ILFIn, IChtOut, ILFout, ISmplFio, IBrnio, ITTFio, IVFio regarding the target intersection TCS [0] included in the analysis processing response. Is generated and displayed on the display device.

  On the screen ImgLnk, for example, as inflow link information, an inflow direction diagram ChtIn (h, k = 0), an inflow link passage form LFIn (h, k = 0), an outflow direction diagram ChtOut (h, k = 0), Outflow link passage form LFout (h, k = 0), branch rate direction form BrnFio (h, k = 0), number direction form form SmplFio (h, k = 0), average speed direction form form VFio (h, k) = 0), an average travel time direction-specific report TTFio (h, k = 0) is included.

  Details of these display contents are as shown in FIGS. 13, 14, 15, 16, 18, 18, 17, and 19, respectively.

  FIG. 23 representatively shows a screen ImgLnk based on display information about the target intersection TCS [0], but the inquiry console 14 similarly displays the target intersections TCS [2] and TCS [5]. It is possible to generate a screen based on the display information about and display it on the display device.

  The user can easily recognize the traveling state of the vehicle 11 around the designated road by looking at the screens ImgSA and ImgLnk.

  Specifically, for example, since the dotted line DL0 is displayed at the position PA shown on the upper right side of the center of the screen ImgSA in FIG. 22, the user combines the subarea indicated by the frame SA0 and the subarea indicated by the frame SA1. You can easily recognize that you are not doing it.

  Since the branching rate indicated by the branching rate tag R01 is 6%, the user travels in the direction of the arrow A00 indicating the inflow direction designated by the user, turns left at the target intersection TCS [0], and is indicated by the frame SA1. It can be easily recognized that the number of vehicles 11 going to the area is small, and it can be determined that it is not necessary to combine the sub area indicated by the frame SA0 and the sub area indicated by the frame SA1.

  In addition, for example, the user can easily recognize that the subarea indicated by the frame SA0 and the subarea indicated by the frame SA2 are not coupled to each other because the dotted line DL1 is displayed at the position PB indicated approximately at the center of the screen ImgSA. can do.

  Then, for example, since the branching rate indicated by the branching rate tag R22 is 100%, the user can determine that it is preferable to combine the subarea indicated by the frame SA0 and the subarea indicated by the frame SA2.

  For example, as to whether or not to combine the sub-area indicated by the frame SA0 and the sub-area indicated by the frame SA2, for example, the cycle length used in the sub-area indicated by the frame SA0 and the cycle length used in the sub-area indicated by the frame SA2 It is determined based on the comparison result.

  Further, for example, since the solid line SL4 is displayed at the position PC shown on the lower right side of the center of the screen ImgSA, the user can easily include the target intersection TCS [5] and the signal intersection MCS5 in the same subarea. Can be recognized.

  For example, since the branching rate indicated by the branching rate tag R52 is 65%, it can be determined that there is no problem with the target intersection TCS [5] and the signalized intersection MCS5 being included in the same subarea.

  Further, for example, since the dotted line DL4 is displayed at the position PD shown on the left side of the center of the screen ImgSA, the user can easily confirm that the subarea indicated by the frame SA2 and the subarea indicated by the frame SA4 are not combined. Can be recognized.

  Since the branching rate indicated by the branching rate tag R53 is 20%, the user travels in the direction of the arrow A50 indicating the inflow direction designated by the user, turns right at the target intersection TCS [5], and is indicated by the frame SA4. It can be easily recognized that the number of vehicles 11 going to the area is small, and it can be determined that it is not necessary to combine the sub area indicated by the frame SA2 and the sub area indicated by the frame SA4.

  In this way, by referring to the screen ImgSA shown in FIG. 22, it is possible to intuitively determine whether or not the current subarea configuration is appropriate. Therefore, such a determination is easily and quickly performed. be able to.

  More specifically, for example, the user can acquire the details of the analysis result of the display intersection by referring to the screen ImgLnk shown in FIG.

  Further, for example, when the user refers to the form shown in FIG. 23 to determine whether or not the current configuration of the sub-area is appropriate, or understands the meaning of the numbers described in the form. When time is required or a human error such as a right or left turn error occurs, a branch rate tag is attached to the screen ImgSA shown in FIG. 22 corresponding to the arrow indicating the traveling direction of the vehicle 11. Therefore, the traveling direction of the vehicle 11 can be visually understood, and the meaning of the number indicated by the branching rate tag can be quickly understood. As a result, analysis time can be shortened and human error can be prevented.

  In addition, although it was set as the structure which produces the display information IImgAlys for displaying screen ImgAlys in the analyzer which concerns on the 1st Embodiment of this invention, it is not limited to this. The analysis apparatus 101 may be configured to create display information for displaying the screen ImgSA shown in FIG. 22 based on the digital road map database.

The analysis apparatus 101 in the travel information analysis system 301 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step of each flowchart below from a memory (not shown). . The program of this apparatus can be installed from the outside. The program of this device is distributed in a state stored in a recording medium.

  FIG. 24 is a flowchart that defines an operation procedure when the analyzer according to the first embodiment of the present invention performs a preparation array creation process and a link correspondence table creation process.

  Referring to FIG. 24, analysis apparatus 101 first sets a total period AUP [h] (step S102).

  Next, the analysis apparatus 101 waits until the set aggregation period AUP [h] has elapsed (NO in step S104). When the aggregation period AUP [h] has elapsed (YES in step S104), the link entry time is aggregated. The preparation information PI included in the period AUP [h] is acquired as probe data (step S106).

  Next, the analyzer 101 creates a preparation array PIAr [h] from the acquired preparation information PI (step S108).

  FIG. 25 is a flowchart defining an operation procedure when the analysis apparatus according to the first embodiment of the present invention performs an analysis process.

  Referring to FIG. 25, analysis apparatus 101 waits until an analysis processing request is received from inquiry table 14 (NO in step S202). When an analysis processing request is received from inquiry table 14 (YES in step S202), the following processing is performed. Perform the process.

  That is, the analysis apparatus 101 acquires, for example, the aggregation period AUP [h] as the analysis period included in the received analysis processing request, and acquires the preparation array PIAr [h] based on the acquired aggregation period AUP [h]. . Further, the analysis apparatus 101 acquires a designated intersection, for example, the target intersection TCS [0], TCS [2], TCS [5], based on the ID of the displayed intersection included in the received analysis processing request. An inflow link correspondence table and an inflow link correspondence table of adjacent intersections are acquired (step S204).

  Next, the analysis apparatus 101 generates an inflow direction map and an inflow link passage form for the target intersections TCS [0], TCS [2], and TCS [5] based on the preparation array PIAr [h] and the inflow link correspondence table. Display information IChtIn and ILFIn for display on the screen are created (step S206).

  Next, the analysis apparatus 101 generates an outflow direction map and an outflow link passage form for the target intersections TCS [0], TCS [2], and TCS [5] based on the preparation array PIAr [h] and the inflow link correspondence table. Display information IhtOut and ILFout to be displayed on the screen are created (step S208).

  Next, based on the preparation array PIAr [h] and the inflow link correspondence table, the analysis apparatus 101 displays a branch rate direction form, a number direction form, an average speed direction form, and an average travel time direction form on the screen, respectively. Display information IBrnFio, ISmplFio, IVFio, ITTFio for display is created (step S210).

  Next, the analyzer 101 creates display information IImgAlys for displaying the subarea configuration diagram on the screen. More specifically, the analysis apparatus 101 creates information ISA for displaying frames SA0 to SA5 indicating sub-areas on the screen based on the digital road map database (step S212).

  Next, the analysis apparatus 101 uses arrows A00, A20, A50 and A01, A02, A03, A22, A51 indicating the inflow direction and the outflow direction specified by the user based on the digital road map database and the display information IChtIn, IChtOut, respectively. , IAin and IAout for displaying A52 and A53 on each screen are created (step S214).

  Next, the analysis apparatus 101 creates information IR for displaying the branching rate on the screen based on the display information IBrnFio (step S216).

  Next, based on the digital road map database, the analysis apparatus 101 displays information for displaying solid lines SL0, SL2, SL4, SL5, SL7, SL9, and SL11 that connect signalized intersections included in the same subarea on the screen. An ISL is created (step S218).

  Next, based on the digital road map database, the analyzer 101 displays on the screen dotted lines DL0, DL1, DL4, DL7, DL10 that connect signalized intersections included in the subarea and signalized intersections included in other subareas. An information IDL for display is created (step S220).

  Next, the analysis apparatus 101 transmits an analysis processing response including the created information to the inquiry console 14 (step S222).

  In step S216, the analysis apparatus 101 is configured to create the information IR for displaying the branching rate on the screen based on the display information IBrnFio. However, the present invention is not limited to this. The analysis apparatus 101 may be configured to directly create information IR for displaying the branching rate on the screen based on the preparation array PIAr [h] and the inflow link correspondence table.

  Further, the order of creating the display information IChtIn, ILFIn, IChOut, ILFout, IBrnio, ISmplFio, IVFio, ITTFio and the information ISA, IAin, IAout, IR, ISL, IDL is not limited to the above, but part or all The order may be changed.

  By the way, in the traffic condition display device described in Patent Document 1, the display unit displays the vehicle at a display position corresponding to the traveling position of the vehicle along the expressway as shown in FIGS. The corresponding vehicle image is displayed. The user recognizes the traveling state of the vehicle traveling on the highway by looking at the display unit.

  However, Patent Document 1 does not disclose a technique for recognizing the traveling state of a vehicle in the vicinity of an intersection that is highly important for analyzing traffic conditions. There is a need for a technique that can provide an analysis result on the traveling state of a vehicle around such an intersection more easily.

  On the other hand, in the analyzer according to the first embodiment of the present invention, the probe data acquisition unit 35 is probe data including the position of the vehicle 11 in a predetermined period and the time corresponding to the position, Probe data of a plurality of vehicles 11 is acquired. The analysis unit 33 displays a screen showing a sub-area that is an intersection where a traffic signal lamp for vehicles is provided and which includes a plurality of same-cycle intersections having the same control cycle length of the vehicle traffic signal lamp. Create information to do. Based on each probe data acquired by the probe data acquisition unit 35, the analysis unit 33 performs a predetermined inflow direction and a predetermined inflow of the vehicle 11 to the display intersection that is at least one of the same-period intersections. Information for displaying a screen indicating one or more outflow directions of the vehicle 11 that has flowed into the display intersection from the direction is created. Then, based on each probe data acquired by the probe data acquisition unit 35, the analysis unit 33 counts the number of vehicles 11 flowing out from the display intersection to the outflow direction with respect to the number of vehicles 11 flowing into the display intersection from a predetermined inflow direction. Create information to display a screen showing the percentage of

  With such a configuration, the sub area, the predetermined inflow direction of the vehicle 11 flowing into the display intersection included in the sub area, the one or more outflow directions from the display intersection of the vehicle 11 that has flowed in, and the ratio are as follows: For example, the user can be made aware through the screen. As a result, the user can see the direction image of the inflow path of the vehicle 11 that flows into the display intersection, the direction image of the outflow path of the vehicle 11 that flows out of the display intersection, and the vehicle that flows into the display intersection from the predetermined inflow direction. For example, the ratio of 11 straight, right, left or U-turns, that is, the branching ratio can be easily recognized. That is, it is possible to provide an analysis result of the traveling state of the vehicle 11 around the intersection more easily. As a result, for example, the user can easily recognize the number of vehicles 11 traveling from the sub area to another sub area based on the branching ratio, so that the sub area and the other sub area are combined. Thus, it is possible to make an appropriate determination as to whether or not to make the same sub-area.

<Second Embodiment>
The present embodiment relates to a travel information analysis system including an analysis device that performs analysis related to a stop as compared to the travel information analysis system according to the first embodiment. The contents other than those described below are the same as those in the travel information analysis system according to the first embodiment.

  FIG. 26 is a diagram illustrating an example of an inflow link that connects between target intersections. Referring to FIG. 26, in the first embodiment of the present invention, the analysis process has been described in detail mainly using the crossing target intersection TCS [0] shown in FIG. Now, the analysis process will be described in detail mainly using the target intersection TCS [0] of the crossroad shown in FIG.

  Referring to FIG. 3 again, aggregation period setting unit 36 in analysis unit apparatus 101 sets aggregation period AUP [h] every 60 minutes, for example. The aggregation period is advanced by 60 minutes as the index h is decreased by one, and is delayed by 60 minutes as the index h is increased by one.

  Referring again to FIG. 6, the probe data acquisition unit 35 is probe data including the position of the vehicle 11 in a predetermined period and the time corresponding to the position, and the plurality of vehicles 11 for a plurality of predetermined periods. Acquire each probe data.

  Specifically, for example, when the total period AUP [h−1] set by the total period setting unit 36 elapses, the probe data acquisition unit 35 stores the preparation information PI shown in FIG. 4 stored in the storage unit 32. From the inside, the preparation information PI whose link entry time is included in the aggregation period AUP [h-1] is acquired as probe data corresponding to the aggregation period AUP [h-1].

  For example, the probe data acquisition unit 35 determines the link entry time from the preparation information PI stored in the storage unit 32 when the next aggregation period AUP [h] of the aggregation period AUP [h−1] has elapsed. The preparation information PI included in the aggregation period AUP [h] is acquired as probe data corresponding to the aggregation period AUP [h].

  In this way, the probe data acquisition unit 35 acquires the probe data of each of the plurality of vehicles 11 for each counting period.

  The probe data acquisition unit 35 outputs preparation information PI corresponding to each acquired total period to the analysis unit 33.

  FIG. 27 is a diagram illustrating a configuration of an analysis unit in the analysis apparatus according to the second embodiment of the present invention.

  Referring to FIG. 27, analysis unit 33 includes an analysis processing unit 50 instead of analysis processing unit 48, as compared with the analysis unit according to the first embodiment of the present invention.

  For example, when the preparation sequence creation unit 44 in the analysis unit 33 acquires the preparation information PI corresponding to the aggregation period AUP [h−1] from the probe data acquisition unit 35, the preparation period PI uses the acquired preparation information PI. -1] is prepared, corresponding to the preparation array PIAr [h-1].

  For example, when the preparation array creation unit 44 acquires the preparation information PI corresponding to the aggregation period AUP [h] from the probe data acquisition unit 35, the preparation array creation unit 44 corresponds to the aggregation period AUP [h] using the acquired preparation information PI. The preparation array PIAr [h] is created.

  The preparation array creation unit 44 stores the prepared preparation array for each aggregation period in the preparation array holding unit 45 and outputs the preparation array to the link correspondence table creation unit 46.

  FIG. 28 is a diagram showing an example of a link correspondence table used in the analysis unit according to the second embodiment of the present invention.

  Referring to FIG. 28, for example, when link correspondence table creation unit 46 receives preparation array PIAr [h] from preparation array creation unit 44, analysis link that connects to the target intersection and uses the target intersection as the end point intersection. A link correspondence table showing a correspondence relationship between the inflow link and the preparation information having information about the inflow link in the preparation array PIAr [h] is created for each target intersection.

  Specifically, when the link correspondence table creation unit 46 selects, for example, the target intersection TCS [k = 0], the link correspondence table creation unit 46 refers to the digital road map database stored in the storage unit 32 and connects to the target intersection TCS [k = 0]. The inflow links IL (1, 0), IL (2, 0) and IL (3, 0) are specified.

  For example, the link correspondence table creation unit 46 sets j1s as an index of preparation information including the same analysis link ID as the analysis link ID indicating the inflow links IL (1, 0), IL (2, 0), and IL (3, 0). ˜j1e, indexes j2s to j2e, and j3s to j3e, respectively.

  Then, the link correspondence table creation unit 46, for example, as shown in FIG. 28, the inflow links IL (1, 0), IL (2, 0) and IL (3, 0) and indexes j1s to j1e, j2s to j2e. And a link correspondence table ILTbl [h] [k = 0] indicating each correspondence relationship with j3s to j3e.

  When the creation of the link correspondence table ILTbl [h] [k = 0] for the target intersection TCS [k = 0] is completed, the link correspondence table creation unit 46 completes the target intersections TCS [k = 1] to TCS [k = Ncs]. The link correspondence tables ILTbl [h] [k = 1] to ILTbl [h] [k = Ncs−1] for −1] are similarly created.

  The link correspondence table creating unit 46 stores the link correspondence table for each aggregation period and for each target intersection in the link correspondence table holding unit 47.

[Analysis processing]
FIG. 29 is a diagram showing an example of a screen displayed on the display device in the inquiry desk according to the second embodiment of the present invention.

  In the screen ImgMap2 shown in FIG. 29, for example, DRM is shown. Here, the upper side of the screen of the screen ImgMap2 is, for example, north.

  On the screen ImgMap2, signalized intersections SCS0 to SCS7, which are intersections where vehicle traffic signal lamps are provided, are shown. Further, on the screen ImgMap2, routes Rt0 to Rt6 connected to the signalized intersection are shown.

  For example, the east-west route Rt0 from the position Ps1 via the signalized intersections SCS3, SCS0, SCS1 to the position Pe1, and the north-south route from the position Ps2 to the signalized intersection SCS0 via the signalized intersections SCS7, SCS6, SCS2 Rt1 is, for example, a main route. On route Rt0, for example, the east direction is the upward direction. On the route Rt1, for example, the north direction is the upward direction.

  Further, for example, four vehicle detectors Det1 to Det4 (not shown) are provided on the route Rt1. More specifically, the vehicle detector Det1 is provided at a position Pd1 between the signalized intersections SCS0 and SCS2, for example. The vehicle detector Det2 is provided, for example, at a position Pd2 between the signalized intersections SCS2 and SCS6. The vehicle detectors Det3 and Det4 are provided at the north side position Pd3 and the south side position Pd4, respectively, between the signalized intersections SCS6 and SCS7, for example.

  Further, for example, two vehicle detectors Det5 to Det6 (not shown) are provided on the route Rt0. More specifically, the vehicle detectors Det5 and Det6 are respectively provided at the east side position Pd5 and the west side position Pd6 between the signalized intersections SCS3 and SCS0, for example.

[Congestion map]
FIG. 30 is a diagram showing an example of a traffic jam display screen displayed on the display device in the inquiry desk according to the second embodiment of the present invention.

  FIG. 30 shows a traffic jam display screen ImgTJ1. The zeroth intersection Vs0, the second intersection Vs2, the sixth intersection Vs6, and the seventh zero intersection Vs7 represent signal intersections SCS0, SCS2, SCS6, and SCS7, respectively.

  The vertical axis indicates the time at the predetermined date and time DT. The horizontal axis indicates, for example, the distance from the starting point of the route Rt1 on the route Rt1 facing north, that is, in the upward direction. The zeroth crossing Vs0, the second crossing Vs2, the sixth crossing Vs6, and the seventh zero crossing Vs7 are shown on the traffic congestion display screen ImgTJ1 at positions corresponding to the distances from the starting points of the signal crossings SCS0, SCS2, SCS6, and SCS7. Has been.

  On the traffic jam display screen ImgTJ1, for example, positions Pd1 to Pd4 on the route Rt1 of four vehicle detectors for sensing a vehicle traveling on the route Rt1 are indicated by arrows Ad1 to Ad4, respectively.

  The user performs an operation for acquiring the traffic congestion display screen ImgTJ1 on the upward route Rt1 while referring to the screen ImgMap2, for example.

  Referring to FIG. 1 again, for example, the inquiry console 14 transmits a traffic index information request to the information storage device 13 based on the contents of the user's operation, and information on traffic jam information that is a response to the transmitted traffic index information request. Receive from the storage device 13.

  For example, the inquiry console 14 draws a region Rtj1 hatched with a diagonally left-down diagonal line on the traffic jam display screen ImgTJ1 based on the traffic jam detection results of the vehicle detectors Det1 to Det4 included in the traffic jam information, and displays it on the traffic jam display screen ImgTJ1. indicate.

  For example, in the traffic jam information, the traffic jam detection result of the vehicle detector Det3 indicates “there is traffic jam” and the traffic jam detection result of the vehicle detector Det4 indicates “no traffic jam” from 7:00 to 16:00. In this case, the inquiry table 14 sets the congestion degree at the position Pd3 of the vehicle detector Det3 to 1 and sets the congestion degree at the position Pd4 of the vehicle detector Det4 to zero from 7:00 to 16:00. Then, for example, the inquiry desk 14 draws the region Rtj1 on the traffic congestion display screen ImgTJ1 by regarding the position where the traffic congestion degree becomes 0.5, specifically, the intermediate point between the positions Pd3 and Pd4 as the end of the traffic congestion.

  For example, the user grasps the traffic jam situation on the route Rt1 in the upward direction on the predetermined date and time DT by referring to the traffic jam display screen ImgTJ1.

  For example, the user performs an operation of selecting these in the order of signalized intersections SCS7, SCS6, SCS2, and SCS0 in order to obtain the analysis result of the traffic jam situation in the north direction of the main route Rt1 while referring to the screens ImgMap2 and ImgTJ1. I do. By this operation, the main route, that is, the route Rt1 becomes the designated route Rt1 designated by the user.

  In addition, the user may, for example, stop position information ISP1 indicating the vehicle stop position every hour from 14:00 to 18:00 between signalized intersections SCS2 and SCS0 on the designated route Rt1 in the upward direction, and on the designated route Rt1 in the upward direction. An operation for acquiring stop position information ISP2 indicating the vehicle stop position for every hour from 7 o'clock to 16 o'clock between signalized intersections SCS7 and SCS6 is performed.

  For example, the inquiry console 14 creates an analysis process request based on the user's operation content, and transmits the created analysis process request to the analysis apparatus 101. The analysis processing request includes, for example, range information indicating the drawing range of the screen ImgMap2, the ID of each signal intersection selected on the designated route Rt1, the selection order of each ID (hereinafter also referred to as selection order ID information), and the stop position. An acquisition request for information ISP1 (hereinafter also referred to as stop position request RISP1), an acquisition request for stop position information ISP2 (hereinafter also referred to as stop position request RISP2), and an analysis period set by the user are included. Here, the analysis period set by the user is, for example, 24 hours from 0:00 to 24:00 of the predetermined date and time DT.

  For example, when the analysis apparatus 101 receives an analysis processing request from the inquiry table 14, the analysis apparatus 101 performs an analysis process according to the received analysis processing request.

  Referring to FIG. 3 again, for example, when the request processing unit 37 in the analysis apparatus 101 receives an analysis processing request from the inquiry console 14, the analysis processing unit 50 in the analysis unit 33 sends an analysis command corresponding to the received analysis processing request. Output to.

  Specifically, the request processing unit 37 acquires range information, selection order ID information, stop position requests RISP1 and RISP2, and an analysis period from the analysis processing request, and performs the following processing.

  That is, the request processing unit 37 refers to the digital road map database stored in the storage unit 32, for example, so that the intersections indicated by the IDs of the signalized intersections SCS7, SCS6, SCS2, and SCS0 included in the selection order ID information are the target intersections. Recognize TCS [7], TCS [6], TCS [2], and TCS [0]. Hereinafter, each of the target intersections TCS [7], TCS [6], TCS [2], and TCS [0] is also referred to as a designated intersection.

  Further, the request processing unit 37 recognizes that the analysis period corresponds to, for example, the aggregation periods AUP [h] to AUP [h-23] based on the aggregation period information received from the aggregation period setting unit 36.

  The request processing unit 37 outputs a stop analysis instruction including each designated intersection and the total period AUP [h] to AUP [h-23] to the analysis processing unit 50 in the analysis unit 33.

  Further, the request processing unit 37 determines the period from 14:00 to 18:00 included in the stop position request RISP1 based on the total period information received from the total period setting unit 36, for example, the total periods AUP [h-10] to AUP [ h-6].

  Further, the request processing unit 37 determines that the period from 7 o'clock to 16 o'clock included in the stop position request RISP2 is based on the aggregation period information received from the aggregation period setting unit 36, for example, the aggregation periods AUP [h-17] to AUP [ h-8].

  The request processing unit 37, for example, includes range information, selection order ID information, ID of each designated intersection, stop position requests RISP1, RISP2, and corresponding counting periods AUP [h-10] to AUP [h-6], AUP [ h-17] to AUP [h-8] are output to the analysis processing unit 50 in the analysis unit 33.

[Stop analysis process]

  Referring to FIG. 31, analysis processing unit 50 includes a stop analysis processing unit 57 and a traffic jam display data creation unit 59.

  When receiving the stop analysis command from the request processing unit 37, the stop analysis processing unit 57 in the analysis processing unit 50 starts the stop analysis processing.

  Specifically, the stop analysis processing unit 57, for example, designates the specified intersection included in the stop analysis instruction, specifically, the target intersections TCS [7], TCS [6], TCS [2], TCS [0], and tabulation Based on the period AUP [h] to AUP [h-23], the following processing is performed.

  That is, the stop analysis processing unit 57, for example, as a link correspondence table for the target intersection TCS [0] in the aggregation periods AUP [h] to AUP [h-23], the link correspondence table ILTbl [h] [ k = 0] and a link correspondence table ILTbl [h−1] [k = 0] to ILTbl [h-23] [k = 0] (not shown) are acquired from the link correspondence table holding unit 47. Similarly, the stop analysis processing unit 57 links the link correspondence table for the target intersections TCS [2], TCS [6], TCS [7] in the aggregation periods AUP [h] to AUP [h-23], for example. Obtained from the table holding unit 47.

  The stop analysis processing unit 57 performs a stop analysis process based on the acquired link correspondence tables and the prepared arrays PIAr [h] to PIAr [h-23] stored in the prepared array holding unit 45, for example.

  Hereinafter, when the aggregation period is AUP [h] and the designated intersection is the target intersection TCS [0], the stop analysis processing unit 57 performs the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr. The stop analysis process performed based on [h] will be described. When the designated intersection is the target intersection TCS [2], TCS [6], or TCS [7], the stop analysis processing unit 57 performs stop analysis based on the corresponding link correspondence table and the preparation array PIAr [h]. The same applies to the processing. When the aggregation period is any of the aggregation periods AUP [h-1] to AUP [h-23], the stop analysis processing unit 57 performs the corresponding link correspondence table and the preparation arrays PIAr [h-1] to PIAr. The same applies to the stop analysis process performed based on the corresponding preparation sequence in [h-23].

[Create information to display inflow direction map and inflow link stop form]
FIG. 32 is a diagram illustrating a configuration of a stop analysis processing unit in the analysis processing unit according to the second embodiment of the present invention.

  Referring to FIG. 32, stop analysis processing unit 57 includes an inflow direction data creation unit 71, an outflow direction data creation unit 72, a composite direction form data creation unit 73, and a histogram creation unit 74.

  FIG. 33 is a diagram showing an example of the inflow direction diagram created by the inflow direction data creation unit in the stop analysis processing unit according to the second embodiment of the present invention. The view of FIG. 33 is the same as that of FIG.

  Referring to FIGS. 32 and 33, the inflow direction data creation unit 71 in the stop analysis processing unit 57 is based on, for example, each probe data for each counting period and for each vehicle 11 acquired by the probe data acquisition unit 35. Information for displaying a screen showing a plurality of inflow directions in which a plurality of vehicles 11 flow into the designated intersection is created.

  Specifically, the inflow direction data creation unit 71, for example, based on the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h], the inflow direction diagram ChtIn (h, k = 0) is created. Display information IChtIn (h, k = 0) is generated.

  For example, the display information IChtIn (h, k = 0) is information for displaying a screen showing a plurality of inflow directions in which a plurality of vehicles 11 flow into a designated intersection.

  The creation process of the display information IhtIn (h, k = 0) in the inflow direction data creation unit 71 is the same as the creation process of the display information IhtIn (h, k = 0) in the inflow direction data creation unit 61 shown in FIG. Since there is, it will be briefly described below.

  That is, the inflow direction data creation unit 71 acquires, for example, from the digital road map database the angles at which the inflow links IL (1, 0), IL (2, 0), IL (3, 0) connect to the designated intersection. The acquired angles are used for drawing arrows DIL (1, 0), DIL (2, 0), and DIL (3, 0) indicating the inflow direction in the inflow direction diagram ChtIn (h, k = 0).

  Similarly, the inflow direction data creation unit 71 displays display information IChtIn (h-1, k = 0) to IChtIn (h-23, k = 0), IChtIn (h, k = 2) to IChtIn (h-23, k = 2), IChtIn (h, k = 6) to IChtIn (h-23, k = 6), and IChtIn (h, k = 7) to IChtIn (h-23, k = 7).

  The inflow direction data creation unit 71 outputs the created display information IChtIn to the request processing unit 37.

  FIG. 34 is a diagram showing an example of the inflow link stop form created by the inflow direction data creation unit in the stop analysis processing unit according to the second embodiment of the present invention.

  Referring to FIG. 34, for example, the inflow direction data creation unit 71 designates for each inflow direction with respect to the designated intersection based on each tabulation period acquired by the probe data acquisition unit 35 and each probe data for each vehicle 11. Information for displaying a screen indicating the time when the vehicle 11 flowing into the intersection stops is created.

  In addition, the inflow direction data creation unit 71 is, for example, a vehicle that flows into the designated intersection for each inflow direction with respect to the designated intersection, based on the respective probe data for each total period acquired by the probe data obtaining unit 35 and for each vehicle 11. Information for displaying a screen indicating the number of times 11 stops is created.

  In addition, the inflow direction data creation unit 71 is, for example, a vehicle that flows into the designated intersection for each inflow direction with respect to the designated intersection, based on the respective probe data for each total period acquired by the probe data obtaining unit 35 and for each vehicle 11. Information for displaying a screen showing the number of 11 is created.

  Specifically, the inflow direction data creation unit 71, for example, based on the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h], the inflow link stop form SFin (h, k = 0) Display information ISFIn (h, k = 0) is generated.

  For example, the display information ISFIn (h, k = 0) indicates the time when the vehicle 11 flowing into the designated intersection stops, the number of times the vehicle 11 flowing into the designated intersection stops, and the number of vehicles 11 flowing into the designated intersection. It is the information for displaying the screen shown for every inflow direction with respect to the designated intersection.

  More specifically, the inflow direction data creation unit 71 refers to, for example, the link correspondence table ILTbl [h] [k = 0] and uses j1s to j1e as the index of the preparation information corresponding to the inflow link IL (1, 0). To get.

  For example, the inflow direction data creation unit 71 uses the number of pieces of preparation information PI [j1s] to PI [j1e] based on the acquired index from the inflow link IL (1, 0) to the designated intersection, that is, the number of data. And the number of counted data, specifically, 100 is written in the column of the 3 o'clock direction in the inflow link stop form SFin (h, k = 0).

  For example, for the preparation information including the vehicle stop information among the preparation information PI [j1s] to PI [j1e], the inflow direction data creation unit 71 acquires one or a plurality of vehicle stop information in the preparation information. The number of acquired vehicle stop information is counted as the number of stops corresponding to the preparation information.

  For example, for the preparation information that does not include the vehicle stop information among the preparation information PI [j1s] to PI [j1e], the inflow direction data creation unit 71 sets the vehicle stop information because the number of stops corresponding to the preparation information is zero. Do not get and stop count.

  For example, the inflow direction data creation unit 71 calculates the total number of stops counted, specifically 56 times. In addition, the inflow direction data creation unit 71 acquires a stop time from each acquired vehicle stop information, for example, and calculates the total of the acquired stop times, specifically 1116 seconds.

  For example, the inflow direction data creation unit 71 divides the total number of stop times and the total stop time by 100 data units to obtain 11.2 seconds and 0.56 times as the average stop time and average stop number. Calculate each.

  For example, the inflow direction data creation unit 71 writes the calculated 11.2 seconds and 0.56 times in the corresponding column of the 3 o'clock direction in the inflow link stop form SFin (h, k = 0).

  Similarly, the inflow direction data creation unit 71 flows into the designated intersection from the inflow link IL (2, 0) based on, for example, the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h]. As the average stop time, average stop count, and count number for the vehicle 11, 75.8 seconds, 0.95 times, and 37 units are calculated, respectively.

  For example, the inflow direction data creation unit 71 writes the calculated 75.8 seconds, 0.95 times, and 37 units in the corresponding column of the 6 o'clock direction in the inflow link stop form SFin (h, k = 0).

  Similarly, the inflow direction data creation unit 71 flows into the designated intersection from the inflow link IL (3, 0) based on, for example, the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h]. As the average stop time, the average number of stops, and the count number for the vehicle 11, 19.1 seconds, 0.79 times, and 85 vehicles are calculated, respectively.

  For example, the inflow direction data creation unit 71 writes the calculated 19.1 seconds, 0.79 times, and 85 units in the corresponding column of the 8 o'clock direction in the inflow link stop form SFin (h, k = 0).

  Similarly, the inflow direction data creation unit 71 displays the display information ISFin (h-1, k = 0) to ISFin (h-23, k = 0), ISFin (h, k = 2) to ISFin (h-23, k = 2), ISFin (h, k = 6) to ISFin (h-23, k = 6), ISFin (h, k = 7) to ISFin (h-23, k = 7) are created. Hereinafter, the display information ISFin (h, k) is also referred to as display information ISFin.

  The inflow direction data creation unit 71 outputs the created display information ISFin to the request processing unit 37.

[Create information to display outflow direction map and outflow link stop form]
FIG. 35 is a diagram showing an example of an outflow direction diagram created by the outflow direction data creation unit in the stop analysis processing unit according to the second embodiment of the present invention. The way of viewing FIG. 35 is the same as that of FIG.

  With reference to FIGS. 32 and 35, the outflow direction data creation unit 72 in the stop analysis processing unit 57 is based on, for example, each probe data for each counting period and for each vehicle 11 acquired by the probe data acquisition unit 35. Information for displaying a screen showing a plurality of outflow directions in which a plurality of vehicles 11 flow out from the designated intersection is created.

  Specifically, the outflow direction data creation unit 72, for example, based on the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h], that is, the adjacent intersections, that is, the target intersections TCS [1] to TCS [3 ] ID is acquired.

  The outflow direction data creation unit 72 is illustrated in FIG. 35 based on, for example, the link correspondence tables ILTbl [h] [k = 1] to ILTbl [h] [k = 3] of adjacent intersections and the preparation array PIAr [h]. Display information IChOut (h, k = 0) for displaying the outflow direction map ChtOut (h, k = 0) is created.

  For example, the display information IChtOut (h, k = 0) is information for displaying a screen showing a plurality of outflow directions in which a plurality of vehicles 11 flow out from a designated intersection.

  The creation process of the display information IChtOut (h, k = 0) in the outflow direction data creation unit 72 is the same as the creation process of the display information IChtOut (h, k = 0) in the outflow direction data creation unit 62 shown in FIG. Since there is, it will be briefly described below.

  That is, the outflow direction data creation unit 72 acquires, for example, the angle at which the inflow links IL (0, 1), IL (0, 2), and IL (0, 3) connect to the designated intersection from the digital road map database. The acquired angles are used for drawing arrows DOL (0, 1), DOL (0, 2), and DOL (0, 3) indicating the outflow direction in the outflow direction diagram ChtOut (h, k = 0).

  Similarly, the outflow direction data creating unit 72 displays the display information IChtOut (h-1, k = 0) to IChtOut (h-23, k = 0), IChtOut (h, k = 2) to IChtOut (h-23). k = 2), IChtOut (h, k = 6) to IChtOutn (h-23, k = 6), IChtOut (h, k = 7) to IChtOut (h-23, k = 7).

  The outflow direction data creation unit 72 outputs the created display information IChtOut to the request processing unit 37.

  FIG. 36 is a diagram showing an example of an outflow link stop form created by the outflow direction data creation unit in the stop analysis processing unit according to the second embodiment of the present invention.

  With reference to FIG. 36, the outflow direction data creation unit 72, for example, causes a plurality of vehicles 11 to flow out of a designated intersection based on the respective probe data for each counting period and for each vehicle 11 acquired by the probe data acquisition unit 35. The information for displaying the screen which shows the time when the vehicle 11 which flows out from the designated intersection stops for each of a plurality of outflow directions is created.

  In addition, the outflow direction data creation unit 72, for example, a plurality of outflow directions in which the plurality of vehicles 11 flow out from the designated intersection based on the respective probe data for each counting period and for each vehicle 11 acquired by the probe data acquisition unit 35. Separately, information for displaying a screen indicating the number of times the vehicle 11 flowing out from the designated intersection has been created is created.

  In addition, the outflow direction data creation unit 72, for example, a plurality of outflow directions in which the plurality of vehicles 11 flow out from the designated intersection based on the respective probe data for each counting period and for each vehicle 11 acquired by the probe data acquisition unit 35. In addition, information for displaying a screen indicating the number of vehicles 11 flowing out from the designated intersection is created.

  Specifically, the outflow direction data creation unit 72 is based on, for example, the link correspondence tables ILTbl [h] [k = 1] to ILTbl [h] [k = 3] of adjacent intersections and the preparation array PIAr [h]. Display information ISFout (h, k = 0) for displaying the outflow link stop form SFout (h, k = 0) is created.

  For example, the display information ISFout (h, k = 0) includes the vehicle 11 flowing out from the designated intersection for the time when the vehicle 11 flowing out from the designated intersection stops, separately from the plurality of outflow directions in which the plurality of vehicles 11 flow out from the designated intersection. Is information for displaying a screen indicating the number of times the vehicle has stopped and the number of vehicles 11 flowing out from the designated intersection.

  More specifically, the outflow direction data creation unit 72 specifies the number of pieces of preparation information having an index corresponding to the inflow link IL (0, 1) in the link correspondence table ILTbl [h] [k = 1], for example. Is counted as the number of vehicles 11 flowing out to the outflow link OL (0, 1), that is, the number of data. The outflow direction data creation unit 72 then writes, for example, the counted number of data, specifically 81, in the 3 o'clock direction column in the outflow link stop form SFout (h, k = 0).

  In addition, the outflow direction data creation unit 72, for example, for the preparation information including the vehicle stop information among the preparation information having an index corresponding to the inflow link IL (0, 1), one or more vehicle stops in the preparation information. Information is acquired, and the number of acquired vehicle stop information is counted as the number of stops corresponding to the preparation information.

  For example, for the preparation information that does not include the vehicle stop information among the preparation information having an index corresponding to the inflow link IL (0, 1), the outflow direction data creation unit 72 has the number of stops corresponding to the preparation information zero. Therefore, vehicle stop information is not acquired and the number of stops is not counted.

  For example, the outflow direction data creation unit 72 acquires the stop time from each acquired vehicle stop information, and calculates the total of the acquired stop times, specifically, 486 seconds. In addition, the outflow direction data creation unit 72 calculates, for example, the total number of stops counted, specifically 24 times.

  For example, the outflow direction data creation unit 72 divides the total number of stops and the total stop time by the number of data 81 units, thereby obtaining 6.0 seconds and 0.30 times as the average stop time and the average number of stops. Calculate each.

  For example, the outflow direction data creation unit 72 writes the calculated 6.0 seconds and 0.30 times in the corresponding columns of the 3 o'clock direction in the outflow link stop form SFout (h, k = 0).

  Similarly, the outflow direction data creation unit 72 flows out from the designated intersection to the outflow link OL (0, 2) based on, for example, the link correspondence table ILTbl [h] [k = 2] and the preparation array PIAr [h]. 23.0 seconds, 0.72 times, and 40 units are respectively calculated as the average stop time, the average number of stops, and the number of counts for the vehicle 11.

  For example, the outflow direction data creation unit 72 writes the calculated 23.0 seconds, 0.72 times, and 40 units in the corresponding column of the 6 o'clock direction in the outflow link stop form SFout (h, k = 0).

  Similarly, the outflow direction data creation unit 72 flows out from the designated intersection to the outflow link OL (0, 3) based on, for example, the link correspondence table ILTbl [h] [k = 3] and the preparation array PIAr [h]. As the average stop time, average stop count, and count number for the vehicle 11, 8.0 seconds, 0.33 times, and 101 vehicles are calculated, respectively.

  For example, the outflow direction data creation unit 72 writes the calculated 8.0 seconds, 0.33 times, and 101 units in the corresponding column of the 8 o'clock direction in the outflow link stop form SFout (h, k = 0).

  Similarly, the outflow direction data creation unit 72 displays the display information ISFout (h-1, k = 0) to ISFout (h-23, k = 0), ISFout (h, k = 2) to ISFout (h-23, k = 2), ISFout (h, k = 6) to ISFout (h-23, k = 6), ISFout (h, k = 7) to ISFout (h-23, k = 7) are created. Hereinafter, the display information ISFout (h, k) is also referred to as display information ISFout.

  The outflow direction data creation unit 72 outputs the created display information ISFout (h, k = 0) to the request processing unit 37.

[Create information to display inflow link stop frequency distribution]
37 to 39 are diagrams illustrating an example of the inflow link stop frequency distribution created by the histogram creation unit in the stop analysis processing unit according to the second embodiment of the present invention for each inflow direction.

  With reference to FIGS. 37 to 39, the histogram creation unit 74 is a vehicle that travels on a route connected to the signalized intersection for each total period acquired by the probe data acquisition unit 35 and based on each probe data for each vehicle 11. Information for displaying a screen capable of recognizing the distribution of 11 stop positions is created.

  Specifically, the histogram creation unit 74 has the vehicle 11 that flows into the designated intersection for each inflow direction with respect to the designated intersection based on the total period acquired by the probe data obtaining unit 35 and each probe data for each vehicle 11. Information for displaying a screen capable of recognizing the distribution of stop positions is generated.

  More specifically, for example, the histogram creation unit 74 flows into the designated intersection for each inflow direction with respect to the designated intersection based on the total period acquired by the probe data obtaining unit 35 and each probe data for each vehicle 11. Information for displaying a screen capable of recognizing the distribution of the relative position of the stop position, which is the position where the vehicle 11 stopped before flowing into the designated intersection, with respect to the designated intersection is created.

  Specifically, the histogram creation unit 74, for example, based on the link correspondence table ILTbl [h] [k = 0] and the preparation array PIAr [h], the inflow link stop frequency distribution HgIn (h, ks = 1, ke = 0), HgIn (h, ks = 2, ke = 0), and display information IHgIn (h, ks = 1, ke = 0) for displaying HgIn (h, ks = 3, ke = 0), respectively. IHgIn (h, ks = 2, ke = 0) and IHgIn (h, ks = 3, ke = 0) are created.

  For example, the display information IHgIn (h, ks = 2, ke = 0) is a screen capable of recognizing the stop position distribution of the vehicle 11 traveling on the designated route Rt1 connected to the target intersection TCS [0]. .

  Further, for example, the display information IHgIn (h, ks = 1, ke = 0), IHgIn (h, ks = 2, ke = 0), IHgIn (h, ks = 3, ke = 0) is included in the target intersection TCS [ 0] is information for displaying a screen capable of recognizing the stop position distribution of the vehicle 11 flowing into the target intersection TCS [0] for each inflow direction with respect to [0].

  More specifically, for example, the histogram creation unit 74 refers to the link correspondence table ILTbl [h] [k = 0], and obtains j1s to j1e as the index of the preparation information corresponding to the inflow link IL (1, 0). To do.

  For example, for the preparation information including the vehicle stop information among the preparation information PI [j1s] to PI [j1e] based on the acquired index, the histogram creation unit 74 acquires one or a plurality of vehicle stop information in the preparation information. The one or more stop positions are acquired from the acquired vehicle stop information.

  For example, for the preparation information that does not include the vehicle stop information among the preparation information PI [j1s] to PI [j1e], the histogram creation unit 74 acquires the stop position because the number of stops corresponding to the preparation information is zero. Not performed.

  For example, the histogram creation unit 74 refers to a digital road map database held by the storage unit 32, and based on each acquired stop position, the target intersection TCS [0] of the road corresponding to the inflow link IL (1, 0). Find each distance from the stop line at.

  For example, the histogram creation unit 74 obtains, for each of the obtained distances, a class corresponding to the distance, specifically, a class every 10 m from zero to 100 m. For example, the histogram creation unit 74 may determine the frequency of the class for every 10 m from zero to 100 m, that is, the number of stoppages based on each obtained class, such as 5, 5, 4, 13, 16, 10, 2, Times, 0 times, and 0 times, and the calculated number of stops is used to create the inflow link stop frequency distribution HgIn (h, ks = 1, ke = 0).

  Similarly, the histogram creation unit 74 acquires, for example, the preparation information indexes j2s to j2e corresponding to the inflow link IL (2, 0), and prepares the preparation information PI [j2s] to PI [j2e] based on the acquired index. Based on this, each distance from the stop line at the target intersection TCS [0] of the road corresponding to the inflow link IL (2, 0) is obtained.

  For example, the histogram creation unit 74 obtains a class for every 10 m from zero to 100 m for each of the obtained distances. For example, the histogram creation unit 74 may select one time, one time, one time, two times, twenty-four times, four times, one time as the frequency of the class for every 10 m from zero to 100 m, that is, the number of stops, based on each obtained class. Times, once, 0 times, and 0 times, and the calculated number of stops is used to create the inflow link stop frequency distribution HgIn (h, ks = 2, ke = 0).

  Similarly, for example, the histogram creation unit 74 acquires the preparation information indexes j3s to j3e corresponding to the inflow link IL (3, 0), and prepares the preparation information PI [j3s] to PI [j3e] based on the acquired index. Based on this, each distance from the stop line at the target intersection TCS [0] of the road corresponding to the inflow link IL (3, 0) is obtained.

  For example, the histogram creation unit 74 obtains a class for every 10 m from zero to 100 m for each of the obtained distances. For example, the histogram creating unit 74 may determine the frequency of the class for every 10 m from zero to 100 m, that is, the number of stops, based on each obtained class, 5, 10, 10, 8, 20, 11, 2, Times, once, 0 times, and 0 times, and the calculated number of stops is used to create the inflow link stop frequency distribution HgIn (h, ks = 3, ke = 0).

  Hereinafter, the display information IHgIn (h, ks, ke) is also referred to as display information IHgIn.

  Similarly, the histogram creation unit 74 creates display information IHgIn for the target intersection TCS [0] in the aggregation periods AUP [h-1] to AUP [h-23]. In addition, the histogram creation unit 74 creates display information IHgIn for the target intersection TCS [2] in the aggregation periods AUP [h] to AUP [h-23]. In addition, the histogram creation unit 74 creates display information IHgIn for the target intersection TCS [6] in the aggregation periods AUP [h] to AUP [h-23]. In addition, the histogram creation unit 74 creates display information IHgIn for the target intersection TCS [7] in the aggregation periods AUP [h] to AUP [h-23].

  The histogram creation unit 74 outputs the created display information IHgIn to the request processing unit 37 and the traffic jam display data creation unit 59.

[Create information to display a traffic jam map]
Referring to FIGS. 29 and 31 again, the traffic jam display data creating unit 59 in the analysis processing unit 50 is information for displaying a screen for judging traffic jams on a designated route, specifically, a statistical vehicle. Stop position information ISP1 and ISP2 indicating the stop positions of the two are created.

  More specifically, when the traffic jam display data creation unit 59 receives a traffic jam analysis command from the request processing unit 37, the traffic jam display data creation unit 59 starts creation processing of the stop position information ISP1 and ISP2 while referring to the digital road map database held by the storage unit 32. To do.

  Specifically, the traffic jam display data creation unit 59 recognizes that the drawing range designated by the user is the range of the screen ImgMap2 shown in FIG. 29 based on the range information included in the traffic jam analysis command, for example.

  In addition, the traffic jam display data creating unit 59 recognizes that the user has requested the analysis result of the traffic jam situation in the north direction of the designated route Rt1 based on the selection order ID information included in the traffic jam analysis command.

  In addition, the traffic jam display data creating unit 59, for example, based on the stop position request RISP1 included in the traffic jam analysis instruction, from 14:00 to 18:00 between the target intersections TCS [2] and TCS [0] on the designated route Rt1 in the upward direction. It is recognized that the stop position information ISP1 indicating the vehicle stop position every hour until the time is requested by the user.

  In addition, the traffic jam display data creation unit 59, for example, includes a total period AUP [h-10] to AUP [h−] in which the period from 14:00 to 18:00 is included in the traffic jam analysis instruction in correspondence with the stop position request RISP1. 6].

  Further, the traffic jam display data creation unit 59, for example, every hour from 7:00 to 16:00 between the signalized intersections SCS7 and SCS6 on the designated route Rt1 in the upward direction based on the stop position request RISP2 included in the traffic jam analysis instruction. It is recognized that the stop position information ISP2 indicating the vehicle stop position is requested by the user.

  In addition, the traffic jam display data creation unit 59, for example, includes the summing periods AUP [h-17] to AUP [h-8 in which the period from 7:00 to 16:00 is included in the traffic jam analysis command in correspondence with the stop position request RISP2. ] Is recognized.

[Generation of Stop Position Information ISP1 Showing Vehicle Stop Position]
The traffic jam display data creation unit 59, for example, from the outflow direction data creation unit 72 in the stop analysis processing unit 57, the target intersections TCS [0], TCS [2], in the total periods AUP [h] to AUP [h-23]. Display information IHgIn about TCS [6] and TCS [7] is received.

  For example, the traffic jam display data creating unit 59 selects the target intersection TCS [2] and the intersection TCS [2] and the AUP [h-10] to AUP [h-6] from the display information IHgIn received from the outflow direction data creating unit 72. Display information IHgIn (h-10, ks = 2, Ke = 0) to IHgIn (h-6, ks = 2, Ke =) as display information IHgIn corresponding to the vehicle 11 traveling in the upward direction between TCS [0]. 0) respectively.

  The traffic jam display data creating unit 59, for example, based on the display information IHgIn (h-10, ks = 2, Ke = 0) to IHgIn (h-6, ks = 2, Ke = 0), the inflow shown in FIG. Inflow link outage frequency distribution HgIn (h-10, ks = 2, ke = 0) to HgIn (h-6, ks = 2, ke) similar to the link outage frequency distribution HgIn (h, ks = 2, ke = 0). = 0).

  For example, the traffic jam display data creation unit 59 obtains the class having the largest number of stops in the inflow link stop frequency distribution HgIn (h-10, ks = 2, ke = 0), and calculates the center value of the obtained class for the aggregation period. It is acquired as the distance from the stop line of the vehicle 11 traveling in the upward direction between the target intersections TCS [2] and TCS [0] at AUP [h-10]. Here, the center value of the class is, for example, 45 m which is the center value of 40 m and 50 m when the class is “40 to 50”.

  Similarly, the traffic jam display data creating unit 59 stops in, for example, the inflow link stop frequency distribution HgIn (h-9, ks = 2, ke = 0) to HgIn (h-6, ks = 2, ke = 0). The class having the largest number of times is obtained, and the center value of each class obtained is calculated between the target intersections TCS [2] and TCS [0] in the aggregation period AUP [h-9] to the aggregation period AUP [h-6]. It is acquired as the distance from the stop line of the vehicle 11 traveling in the direction.

  The traffic jam display data creation unit 59 creates stop position information ISP1 including each acquired distance and the corresponding total period AUP [h-10] to total period AUP [h-6], and creates the generated stop position information ISP1. Output to the request processing unit 37.

[Generation of Stop Position Information ISP2 Showing Vehicle Stop Position]
Similarly, the traffic jam display data creation unit 59, for example, from the display information IHgIn received from the outflow direction data creation unit 72, during the aggregation periods AUP [h-17] to AUP [h-8], the target intersection TCS [ 7] and TCS [6] as display information IHgIn corresponding to vehicle 11 traveling in the upward direction, display information IHgIn (h-17, ks = 7, Ke = 6) to IHgIn (h-8, ks = 7). , Ke = 6) respectively.

  The traffic jam display data creating unit 59, for example, based on the display information IHgIn (h-17, ks = 7, Ke = 6) to IHgIn (h-8, ks = 7, Ke = 6), the inflow link stop frequency distribution HgIn. (H-17, ks = 7, ke = 6) to HgIn (h-8, ks = 7, ke = 6) are acquired.

  For example, the traffic jam display data creating unit 59 has the highest number of stops in the inflow link stop frequency distribution HgIn (h-17, ks = 7, ke = 6) to HgIn (h-8, ks = 7, ke = 6). Each large class is obtained, and the center value of each class obtained is traveling in the upward direction between the target intersections TCS [7] and TCS [6] during the aggregation period AUP [h-17] to the aggregation period AUP [h-8]. It is acquired as the distance from the stop line of the vehicle 11 to be operated.

  The traffic jam display data creation unit 59 creates stop position information ISP2 including each acquired distance and the corresponding total period AUP [h-17] to total period AUP [h-8], and the generated stop position information ISP2 is generated. Output to the request processing unit 37.

  Referring to FIG. 3 again, for example, the request processing unit 37 receives, from the stop analysis processing unit 57 in the analysis processing unit 50, the target intersections TCS [0], TCS in the total periods AUP [h] to AUP [h-23]. Display information IChtIn, ISFIn, IChOut, ISFout, and IHgIn for [2], TCS [6], and TCS [7] is received as a response to the stop analysis command.

  Further, for example, the request processing unit 37 receives the stop position information ISP1 and ISP2 from the traffic jam display data creation unit 59 in the analysis processing unit 50 as a response to the traffic jam analysis command.

  Then, for example, the request processing unit 37 displays the display information IChtIn for the target intersections TCS [0], TCS [2], TCS [6], and TCS [7] in the aggregation period AUP [h] to AUP [h-23]. , ISFIn, IChOut, ISFout, IHgIn, and the analysis processing response including the stop position information ISP1, ISP2 is transmitted to the inquiry console 14.

[Processing at the inquiry desk]
FIG. 40 is a diagram showing an example of a traffic jam display screen displayed on the display device in the inquiry desk according to the second embodiment of the present invention. 40 is the same as FIG.

  FIG. 41 is a diagram showing an example of a screen displayed on the display device in the inquiry desk according to the second embodiment of the present invention.

  1, 29, 30, 40, and 41, when inquiry table 14 receives an analysis processing response, which is a response to an analysis processing request, from analysis device 101, for example, inquiry table 14 performs the following processing.

  That is, the inquiry console 14 draws the X marks surrounded by the dotted lines SP1 and SP2 on the traffic jam display screen ImgTJ1 shown in FIG. 30 based on the stop position information ISP1 and ISP2 included in the analysis processing response, respectively. Thus, the traffic jam display screen ImgTJ2 shown in FIG. 40 is created. The traffic jam display screen ImgTJ2 is a screen for determining traffic jam on the designated route Rt1, for example.

  Further, on the traffic jam display screen ImgTJ2, as with the traffic jam display screen ImgTJ1, for example, positions Pd1 to Pd4 of vehicle detectors for sensing vehicles traveling on the route Rt1 are indicated by arrows Ad1 to Ad4, respectively. The inquiry console 14 displays the created traffic jam display screen ImgTJ2 on the display device.

  Here, the crosses surrounded by the dotted line SP1 on the traffic jam display screen ImgTJ2 are vehicle stop positions every hour from 14:00 to 18:00 between the signalized intersections SCS2 and SCS0 on the designated route Rt1 in the upward direction. In addition, the crosses surrounded by the dotted line SP2 are vehicle stop positions every hour from 7 o'clock to 16 o'clock between the signalized intersections SCS7 and SCS6 on the designated route Rt1 in the upward direction.

  Further, for example, the inquiry table 14 displays the screen shown in FIG. 41 based on the display information IChtIn, ISFIn, IhtOut, ISFout, IHgIn about the target intersection TCS [0] in the aggregation period AUP [h] included in the analysis processing response. ImgStp is generated and displayed on the display device.

  On the screen ImgStp, for example, as inflow information, an inflow direction chart ChtIn (h, k = 0), an inflow link stop form SFIn (h, k = 0), an outflow direction chart ChtOut (h, k = 0), outflow Link stop form SFout (h, k = 0), inflow link stop frequency distribution HgIn (h, ks = 1, ke = 0), HgIn (h, ks = 2, ke = 0), HgIn (h, ks = 3) , Ke = 0).

  Details of these display contents are as shown in FIGS. 33, 34, 35, 36, 37, 38, and 39, respectively.

  In FIG. 41, the screen ImgStp based on the display information about the target intersection TCS [0] in the aggregation period AUP [h] is representatively shown, but the inquiry console 14 similarly displays other aggregation periods. Alternatively, a screen based on display information about another target intersection can be generated and displayed on the display device.

[Example of vehicle speed threshold improvement in vehicle detector]
As described above, the inquiry table 14 draws the region Rtj1 on the traffic congestion display screen ImgTJ1, that is, ImgTJ2, considering the intermediate point between the positions Pd3 and Pd4 where the traffic congestion degree is 0.5 as the end of the traffic jam based on the traffic jam information, for example. doing.

  On the other hand, the vehicle stop position based on the stop position information ISP2 from the analysis apparatus 101, which is indicated by the x mark surrounded by the dotted line SP2, does not reach the position of the vehicle detector Dt3, that is, the position indicated by the arrow Ad3. The user can determine that the end is downstream of the position indicated by the arrow Ad3.

  Therefore, for example, the user can recognize that it is necessary to review the vehicle speed threshold value of the vehicle detector Det3 so that the congestion detection result for the vehicle detector Det3 does not indicate “congested”.

  For example, when the vehicle speed obtained from the detection result of the vehicle detector Det3 is 9 km / h and the vehicle speed threshold of the vehicle detector Det3 is 10 km / h, the vehicle speed threshold of the vehicle detector Det3 Is changed to 8 km / h, the traffic jam detection result for the vehicle detector Det3 can be changed from “with traffic” to “without traffic”.

  As a result, the downstream side end of the region Rtj1 drawn on the traffic jam display screen ImgTJ2 by the inquiry console 14 moves to, for example, an intermediate point between the positions Pd2 and Pd3 as a traffic jam degree of 0.5. It is possible to match the region Rtij based on the vehicle stop position based on the stop position information ISP2 from the analysis apparatus 101.

  In the traffic jam display screen ImgTJ2, no traffic jam occurs between the position of the vehicle detector Det1 indicated by the arrow Ad1 and the position of the vehicle detector Det2 indicated by the arrow Ad2, except for 8:00 to 10:00. .

  On the other hand, the vehicle stop position based on the stop position information ISP1 from the analysis apparatus 101, which is indicated by the x mark surrounded by the dotted line SP1, exists between the position Pd1 of the vehicle detector Dt1 and the position Pd2 of the vehicle detector Dt2. Therefore, the user can estimate that a traffic jam has occurred between the vehicle detector Dt1 and the vehicle detector Dt2.

  Therefore, for example, the user can recognize that it is necessary to review the vehicle speed threshold value of the vehicle detector Det1 so that the congestion detection result for the vehicle detector Det1 indicates “congested”.

  For example, when the vehicle speed obtained from the detection result of the vehicle detector Det1 is 7 km / h and the vehicle speed threshold of the vehicle detector Det1 is 5 km / h, the vehicle speed threshold of the vehicle detector Det1 Is changed to 10 km / h, the traffic jam detection result for the vehicle detector Det1 can be changed from “no traffic jam” to “has traffic jam”.

  Thereby, for example, when the traffic jam detection result of the vehicle detector Det2 is “no traffic jam”, the inquiry table 14 indicates that, for example, the head of the traffic jam is the zeroth intersection Vs0 and the traffic jam ends between the positions Pd1 and Pd2. Since the area that is the point is drawn on the traffic jam display screen ImgTJ2, the area Rtij based on the traffic jam information and the vehicle stop position based on the stop position information ISP1 from the analyzer 101 can be matched.

  As described above, by setting the vehicle speed threshold set in the vehicle detector to an appropriate value, the accuracy of the traffic jam information based on the traffic jam detection result of the vehicle detector can be improved. The accuracy of the congestion length drawn on the display screen ImgTJ2 can be improved. As a result, for example, the split of an important intersection located downstream of traffic jams, that is, the distribution ratio of green hours can be set to an optimal value, so that the occurrence of traffic jams can be delayed or traffic jams can be eliminated early. it can. That is, the signal control quality of the entire intersection can be improved.

[Modification]
Referring to FIG. 3 again, the analysis unit 33 displays information for displaying a screen capable of recognizing the distribution of the stop positions of the vehicle 11 traveling on the route, separately from the plurality of inflow routes to the signalized intersection. Information for creating and displaying a screen for judging traffic jams on the route is created.

  Referring to FIG. 29 again, for example, the user obtains a signal for the purpose of obtaining the analysis result of the traffic condition in the east direction of the route Rt0 and the analysis result of the traffic condition in the north direction of the route Rt1 while referring to the screen ImgMap2. An operation of selecting these in the order of the intersections SCS3, SCS0, and SCS1 and an operation of selecting them in the order of the signalized intersections SCS7, SCS6, SCS2, and SCS0 are performed. By these operations, the routes Rt0 and Rt1 become designated routes Rt0 and Rt1 designated by the user.

  Further, for example, the user obtains stop position information ISP3 indicating the vehicle stop position every hour from 14:00 to 18:00 between the signalized intersections SCS3 and SCS0 on the designated route Rt0 in the east direction from the analyzer 101. An operation and an operation for acquiring the stop position information ISP1 and ISP2 described above from the analyzer 101 are performed.

  For example, the inquiry console 14 creates an analysis process request based on the user's operation content, and transmits the created analysis process request to the analysis apparatus 101.

  For example, when the analysis apparatus 101 receives an analysis processing request from the inquiry table 14, the analysis apparatus 101 performs an analysis process according to the received analysis processing request.

  For example, the analysis apparatus 101 displays the display information IHgIn (h-10, ks = 3, Ke = 0) to IHgIn (h-6, ks = 3, Ke = 0) as in the case of creating the stop position information ISP1. The stop position information ISP3 is created using the inflow link stop frequency distribution HgIn (h-10, ks = 3, ke = 0) to HgIn (h-6, ks = 3, ke = 0) based on the above.

  For example, the analysis apparatus 101 transmits an analysis processing response to the inquiry table 14. Here, the analysis processing response is for the designated intersection Rt1 with respect to the target intersections TCS [0], TCS [2], TCS [6], TCS [7] in the aggregation periods AUP [h] to AUP [h-23]. Display information IChtIn, ISFIn, IChOut, ISFout, IHgIn, and stop position information ISP1, ISP2 are included. In addition, the analysis processing response includes the display information IChtIn, ISFIn, and the display information about the target intersections TCS [1], TCS [0], and TCS [3] in the total period AUP [h] to AUP [h-23] for the designated route Rt0. IhtOut, ISFout, IHgIn, and stop position information ISP3 are included.
