Description

  The present invention relates to a congestion information collection and display device, a congestion information management server, a congestion information display system, and a congestion information display for grasping the congestion state in a place where a moving body such as a person or a vehicle may gather or move. The present invention relates to a method and a congestion information display program.

  When a disaster such as a major earthquake occurs and public transportation such as a train stops, a large number of people need to move from a place of work or the like to a residence such as a home by walking or using a vehicle. In such a case, it is necessary to accurately grasp the movement status of an object such as a person or a vehicle from the viewpoint of providing various conveniences for the passage of the emergency vehicle or the person who is moving. Even in places such as amusement parks and sightseeing spots where objects such as people and vehicles may be crowded, it is often necessary to deploy people and equipment according to the congestion situation.

  Therefore, as a related technique of the present invention, an RFID (Radio Frequency IDentification) tag is arranged at a predetermined specific location such as an entrance of a department store, and the congestion state of an object is grasped from data of a mobile terminal that detects the tag. Has been proposed (see, for example, Patent Document 1). In this related technology, an RFID tag reader is mounted on a portable terminal such as a cellular phone. The portable terminal performs an RFID tag detection operation every predetermined time, and transmits the ID of the detected RFID tag and the ID (Identification) of the own terminal to the information collection server together with the location information of the current location.

  The information collection server can grasp the congestion status of objects in various places from the geographical distribution of the mobile terminals that have transmitted. In addition, it is possible to grasp the temporal movement of these mobile terminals specified from the ID.

Japanese Patent Laying-Open No. 2005-196610 (paragraphs 0041 to 0043, FIG. 1)

  However, in this related technology, the information collection server grasps the number of portable terminals that have detected the RFID tag. Therefore, in this related technology, it is necessary to grasp the congestion status of a portable terminal that has both a tag reader that detects an RFID tag and a GPS (Global Positioning System) function. Persons who do not have portable terminals themselves and vehicles on which only these persons get on are excluded from the object of grasp.

  In addition, in a case where the congestion state of a person is to be grasped, information on a person who has a plurality of portable terminals in the kitchen cannot be accurately reflected. In addition, even when the congestion state of the vehicle is to be grasped, the number cannot be accurately grasped when a plurality of people are on one vehicle.

  Furthermore, in this related technique, it is necessary to arrange RFID tags at various places where measurement is to be performed. The communication distance between the RFID tag and the tag reader is generally as short as several meters or less. Therefore, it is often unsuitable for detecting a portable terminal carried by a person inside the vehicle. In addition, when trying to grasp only the pedestrian congestion situation, if it is attempted to expand the area to be grasped, it is necessary to arrange a large number of RFID tags on the ground in the form of a mesh, which is difficult to realize. In many cases.

  Therefore, an object of the present invention is to provide a congestion information collection and display device that can grasp the congestion status of objects such as people in each place without depending on the number of these terminals by providing the terminals with a predetermined function, The object is to provide a congestion information management server, a congestion information display system, a congestion information display method, and a congestion information display program.

  <Embodiment of the Invention>

  Next, an embodiment of the present invention will be described.

FIG. 6 shows an outline of the configuration of the congestion information display system according to the embodiment of the present invention. The congestion information display system 100 is connected to a congestion information management server 102 for system management on the Internet 101. The first to Mth radio base stations 103 _{1 to} 103 _M are connected to the Internet 101 directly or via a communication network (not shown).

The first to M-th radio base stations 103 _{1 to} 103 _M can communicate with radio terminals existing in the communication areas under their jurisdiction by radio. Here as an example, the first radio base station 103 ₁ is assumed communicates with the mobile terminal 105 and the radio in possession of the user 104. The M-th radio base stations 103 _{1 to} 103 _M communicate with the in-vehicle terminal 107 provided in the vehicle 106 by radio. There are an arbitrary number of portable terminals 105 and in-vehicle terminals 107 that use the congestion information display system 100, but here, one representative is shown here.

The GPS satellite 108 is used as a GPS system satellite that provides position information to the mobile terminal 105 and the in-vehicle terminal 107. In FIG. 6, only one GPS satellite 108 is shown, but actually, positioning is performed using a plurality of GPS satellites simultaneously. Of course, the position information of the mobile terminal 105 and the in-vehicle terminal 107 can be roughly acquired in a form corresponding to the known position information of each of the _first to M-th radio base stations 103 _{1 to} 103 _M.

The GPS information acquisition unit 116 acquires GPS information from the GPS satellite 108 and calculates the current position (latitude and longitude) of the mobile terminal 105 and time data. A radar (radio detection and ranging) transmission unit 117 transmits predetermined electromagnetic waves such as millimeter waves and infrared rays to the periphery of the mobile terminal 105. The radar receiver 118 receives a reflected wave when the electromagnetic wave transmitted by the radar transmitter 117 is reflected from an object. The radar drive unit 119 performs control to rotate the direction of the electromagnetic wave transmitted from the radar transmission unit 117 in a horizontal plane. The signal extraction unit 120 performs control to extract a signal when the radar reception unit 118 successfully receives signals in all directions.

  The information storage unit 121 stores predetermined information such as data received by the radar receiver 118. The information storage unit 121 may be configured as a partial area of the memory 112. The density calculation unit 122 calculates the density of the object in a predetermined area around the mobile terminal 105 using the measurement result stored in the information storage unit 121. The input unit 123 includes an operation unit (not shown), and the user 104 inputs necessary data. The display unit 124 is a display unit configured by a display such as a liquid crystal display or an organic EL display (organic electroluminescence display). The general portable function unit 125 is a circuit part that realizes other circuit functions generally provided as a portable terminal. For example, when the mobile terminal 105 is a mobile phone, the general mobile function unit 125 includes a call function and a camera function.

  FIG. 8 shows the configuration of an in-vehicle terminal applicable to the congestion information display system in this embodiment. This will be described with reference to FIGS.

  The in-vehicle terminal 107 includes a control unit 133 that includes a CPU 131 and a memory 132.

  The wireless communication control unit 135 to the display unit 144 are configured by substantially the same circuit devices as the wireless communication control unit 115 to the display unit 124 illustrated in FIG. The general in-vehicle terminal function unit 145 is a circuit device portion that is provided as a general in-vehicle terminal and is not included in the other circuit devices described above.

  FIG. 9 shows an outline of the configuration of the congestion information management server of this embodiment. This will be described with reference to FIG.

  The congestion information management server 102 includes a control unit 153 that includes a CPU 151 and a memory 152. The CPU 151 controls the following units connected to the communication unit 154 such as a data bus by executing a control program stored in the memory 152. Further, the control unit 153 can also realize at least a part of these units by software by executing a control program.

  The transmission unit 155 performs processing for transmitting necessary data in the congestion information management server 102 via the Internet 101. The receiving unit 156 performs processing for receiving data sent from the mobile terminal 105, the in-vehicle terminal 107, or other devices via the Internet 101. These data include, for example, measurement data consisting of radar measurement results (density information) sent from the mobile terminal 105 and the in-vehicle terminal 107, the latitude and longitude of the measurement position, and incidental information representing the measurement time, and the desired region. An example is an area information request signal that requests acquisition of congestion information.

The database processing unit 157 performs processing of the congestion information database 158 provided in the congestion information management server 102. The congestion information database 158 stores measurement data of each measurement point sent from the mobile terminal 105 or the in-vehicle terminal 107 and map data of each place. The image generation unit 159 generates an image indicating the degree of congestion in each region based on the result processed by the database processing unit 157. Image data representing an image generated by the image generation unit 159 is transmitted by the transmission unit 155 to a request destination in response to a request from the _first to M-th radio base stations 103 _{1 to} 103 _M or a communication terminal (not shown). ing.

  Incidentally, the user 104 shown in FIG. 6 is a member of the congestion information display system 100. The user 104 declares his / her place of residence, moving area, and scheduled movement time to the congestion information management server 102 in advance, and is designated at a designated time zone according to an instruction from the administrator of the congestion information display system 100. A predetermined point can be acquired by uploading measurement data representing congestion information around the current location to the congestion information management server 102.

  Also, the user 104 can accumulate the acquired points and exchange them for desired products, or acquire the congestion status of the area he wants to check as many times as the number of points. Of course, the user 104 who lacks points or a person who is not a member of the congestion information display system 100 downloads information indicating the degree of congestion in a desired area from the congestion information management server 102 to his / her terminal by paying a predetermined fee. The downloaded contents can be displayed and printed.

  FIG. 10 shows the processing of the portable terminal when uploading measurement data to the congestion information management server. This will be described with reference to FIGS.

  The control unit 113 of the portable terminal 105 waits for the user 104 to connect to the congestion information management server 102 from a menu screen (not shown) and select an upload item displayed on the display unit 124 at that time (step). S201). When the upload item is selected (Y), the control unit 124 activates the GPS information acquisition unit 116 (step S202). Thereby, the radar drive unit 119 starts driving (step S203).

  The radar drive unit 119 is composed of a unit arranged at the uppermost part of the casing (not shown) of the mobile terminal 105. In this unit, although not shown, when the rectangular housing of the portable terminal 105 is erected on a horizontal plane, a small motor having a vertical direction as a rotation axis, an antenna attached to the rotation axis, and a vertical direction that knows the vertical direction A detection sensor is arranged.

  When the above-described small motor starts rotating by the start of driving of the radar drive unit 119, the radar transmission unit 117 and the radar reception unit 118 start operating, and a predetermined millimeter wave is transmitted from the antenna. At this time, the radar receiver 118 receives the reflected wave from the same antenna within a range of about 10 meters from the location of the mobile terminal 105 (step S204). The reflected wave data received by the radar receiver 118 is stored in the information storage unit 121 in synchronization with the rotation angle information indicating the rotation angle of the small motor.

  Incidentally, the user 104 is required to erect the portable terminal 105 in the vertical direction within a predetermined allowable range while the radar driving unit 119 is driven. This is because the antenna attached to the rotating shaft of the small motor described above becomes a condition for rotating on a horizontal plane. Of course, when the portable terminal 105 exists at a considerably high place from the ground, it is necessary that the built-in antenna be attached to the rotation shaft at an angle that looks down on the ground.

  However, in this example, it is assumed that the user 104 fixes the portable terminal 105 to a tripod or holds it in a stable position. Therefore, it is not necessary to substantially consider the depression angle. Of course, it is possible to attach the antenna to the rotary shaft of the above-mentioned small motor at an angle that looks down on the ground in consideration of the depression angle. The user 104 can send test data to the congestion information management server 102 in advance to check the actual usage of the mobile terminal 105 and make adjustments during measurement.

  The signal extraction unit 120 checks whether or not the vertical detection sensor maintains a range that can be regarded as “vertical” continuously for a period of at least one rotation when the rotation shaft of the small motor rotates a predetermined number of times. To do. When it is confirmed that the reflected wave data for at least one rotation is received within the range that can be regarded as “vertical”, it is determined that the data extraction in all directions is successful (step S205: Y). The reflected wave data is extracted from the information storage unit 121, and a successful display is performed on the display unit 124 (step S206). A sound or melody indicating success may be output for a short time from a speaker (not shown) provided in the general portable function unit 125 together with the success display.

  On the other hand, when the rotation shaft of the small motor is rotated a predetermined number of times, a range in which the vertical detection sensor can be regarded as “vertical” is detected while the rotation angle is rotated by 360 degrees in any section. If the “vertical” state does not continue within the range of the rotation angle of 360 degrees even if it is detected, it is determined that the omnidirectional data extraction has not been successful (step S205: N). In this case, the electromagnetic wave transmitted from the radar transmitter 117 has not been transmitted from the portable terminal 105 in the horizontal direction for one rotation, and the reflected wave data received by the radar receiver 118 cannot be employed.

  Therefore, if the omnidirectional data extraction is not successful (step S205: N), an error is displayed on the display unit 124 (step S207). A sound or melody indicating failure may be output from the above-mentioned speaker together with this error display.

  In this case, a display for inputting whether or not to retry the measurement such as “Do you want to remeasure” is displayed on the display unit 124. When the user 104 selects re-measurement (step S208: Y), the process returns to step 204 and the measurement by the radar is attempted again. At this time, the user 104 naturally corrects the rotating shaft of the small motor in the “vertical” direction.

  When an error is displayed and the user 104 gives up re-measurement (step S208: N), the control unit 113 stops the radar transmission unit 117, the radar reception unit 118, the GPS information acquisition unit 116, and the radar drive unit 119, respectively. (Step S209). Thereafter, the control unit 113 disconnects the connection with the congestion information management server 102 (step S210). In this case, the process ends (end) without successful transmission of measurement data.

  On the other hand, when the omnidirectional data has been successfully extracted (step S205: Y) and the display unit 124 has been successfully displayed (step S206), the control unit 113 includes the radar transmission unit 117, the radar reception unit 118, and the radar drive. Each of the units 119 is stopped (step S211). Then, the extracted omnidirectional data is sent to the density calculation unit 122, where the ratio of the area occupied by the object to the effective range of the radar is calculated, the density is obtained, and the radar measurement result is created (step S212). A method of calculating the density in each measurement area will be described later.

  FIG. 11 shows an example of the radar measurement result as an image. In this example, the measurement data of the portable terminal 105 shown in FIG. 6 is processed for display, and an image when it is assumed that a display like a normal radar device is displayed on the display is shown. This is different from the image reproduced from the measurement data itself sent to the server 102. This will be described with reference to FIG.

  The display 171 includes a concentric distance-identifying dividing line 172 indicated by a broken line, a measurement azimuth line 173 indicated by a solid line with each measurement azimuth indicated by an angle of 10 degrees from the center of the concentric circle, and each measurement azimuth reference An azimuth dividing line 174 that indicates the azimuth at the intermediate position of each azimuth indicated by the line 173 is displayed as a reference line.

  The center position of the concentric circle formed by the distance identification dividing line 172 becomes the measurement point of the portable terminal 105. In addition, the distance from the measurement point to the distance identification dividing line 172 displayed on the outermost side is 10 meters in this example. In other words, a total of ten concentric distance identification dividing lines 172 are displayed at 1-meter intervals. However, it is difficult to interpret the distance identifying dividing line 172 closest to the center because of the drawing. Data in a range exceeding a radius of 10 meters measured by one portable terminal 105 is deleted in the course of processing.

  A black circle (●) 175 displayed on the display 171 indicates that an object that reflects electromagnetic waves such as a person exists at the center of each display position on the data. Here, it is assumed that an example of a state where people of almost the same size are gathered in a plaza such as a schoolyard is shown. In this case, since each person is recognized as a reflector of substantially the same size, the size of the black circle 175 is drawn as substantially the same size. In this example, the congestion state of only an object that can be regarded as a person is shown. However, if a vehicle is present in this area, a figure such as a rectangle having an external size corresponding to the vehicle is displayed at the position of the vehicle. It will be.

  In the example shown in FIG. 10, several states in which a plurality of black circles 175 are arranged in the same direction are shown. When the mobile terminal 105 is located at a position somewhat higher than the ground where the person is present, not only the person in front of the mobile terminal 105 but also the person behind the mobile terminal 105 is directly irradiated with electromagnetic waves from the radar transmitter 117. Therefore, a state in which a plurality of black circles 175 are arranged in the same direction can be detected and created without any problem. As described above, even if the portable terminal 105 is not so different from the height at which a person is present, it is possible to use the diffraction of light in the reflected wave or synthesize data obtained from a plurality of different measurement points. The presence of an object located rearward when viewed from the terminal 105 can be detected and displayed in the same manner.

  FIG. 12 shows another example of the radar measurement result. Here, the location where the portable terminal 105 shown in FIG. 6 exists is set as the origin, and the distance of the center position of the detected object at each angle is shown as numerical data. The measurement result shown in FIG. 12 does not correspond to the image of FIG.

  In FIG. 12, objects are detected at a plurality of distances with respect to one angle (azimuth). As described with reference to FIG. 11, this uses a mobile terminal 105 having a height substantially equal to the height of a person. Can be detected. In FIG. 12, the detection of the object is performed in units of 10 degrees, but in FIG. 11, the detection of the object is performed in units of 1 degree or the like finer than this.

  Next, the principle of density detection for each area using such radar measurement results will be described. The density calculation unit 122 of the portable terminal 105 shown in FIG. 7 and the density calculation unit 142 of the in-vehicle terminal 107 shown in FIG. 8 are areas having a radius of 10 meters in the case of the example shown in FIG. The density (congestion degree) of an object such as a person is calculated.

  FIG. 13 shows a state of calculation processing of the density calculation unit. Here, although it demonstrates as a process of the density calculation part 122 of the portable terminal 105 using FIG.7 and FIG.11, the process of the density calculation part 142 of the vehicle-mounted terminal 107 shown in FIG. 8 is performed similarly.

  The density calculation unit 122 first initializes the parameter P for calculation to “1” (step S231). Then, it is checked whether an object exists in at least a part of the Pth unit area (step S232). Here, the unit area refers to a minimum unit area surrounded by a substantially rectangular frame partitioned by a distance identification dividing line 172, a measurement azimuth line 173, and each measurement azimuth reference line 173 in FIG. In the example shown in FIG. 11, a circle with a radius of 10 meters is divided into 720 unit regions. Each of these unit areas is numbered from “1” to “720”.

  When the parameter P is “1”, it is checked whether or not even a part of the black circle 175 exists in the first unit area. At this time, whether there is one black circle 175 or two or more in the unit area, it is determined that “exists”. As described above, if even a part of the object is present in the focused unit area (step S232: Y), the unit area is set to “1” (step S233).

  On the other hand, there is a case where some objects do not exist in the target unit area (step S232: N). In this case, the unit area is set to “0” (step S234).

If the process of step S233 or step S234 is performed, it is checked in step S235 whether the current parameter P is greater than or equal to the maximum value P _{MAX of the} unit area. In this example, the parameter P _MAX is the value “720”. Since the current parameter P is “1”, it is less than the maximum value P _MAX (N). In this case, the parameter P is incremented by “1” (step S236), and the process proceeds to step S232. Thus, until the parameter P reaches the maximum value P _MAX and at least a part of the black circle 175 is “existing” in the unit area, the target area of 251 square meters as an area with a radius of 10 meters is checked. Similar processing is repeated for each part of the region.

If it is determined in step S235 that the current parameter P has reached the maximum value P _MAX of the unit area (Y), an integrated value A with the unit area set to “1” is calculated in step S233 (step S233). S237). Then, the density (degree of congestion) in the area with a radius of 10 meters is calculated (step S238), and the density calculation process of the density calculation unit 122 is ended (END). The density is expressed as a percentage of the integrated value A divided by the maximum value P _MAX of the unit area.

  Returning to FIG. When the process of step S211 is completed, the control unit 113 calculates the density (congestion status) of the area measured using the density calculation unit 122, and sets this as the radar measurement result (step S212). Next, incidental information including the latitude and longitude of the measurement point and the measurement time is created using the GPS information acquisition unit 116 activated in step S202 (step S213).

  When the auxiliary information is created, the GPS information acquisition unit 116 is stopped (step S214), and the measurement data including the radar measurement result and the auxiliary information is transmitted to the congestion information management server 102 (step S215). Of course, if the GPS information acquisition unit 116 is being used by other application software, whether or not to stop depends on the application software.

  When the measurement data is transmitted to the congestion information management server 102, the connection with the congestion information management server 102 is terminated (step S210), and a series of processes for uploading the measurement data to the congestion information management server is terminated (end). ).

  The in-vehicle terminal 107 shown in FIG. 6 can upload measurement data to the congestion information management server in the same manner as the portable terminal 105. For this reason, the description about the upload process of the measurement data by the vehicle-mounted terminal 107 is omitted. Of course, in the case of the in-vehicle terminal 107, the antenna where the radar transmitter 137 and the radar receiver 138 in FIG. In addition, since the antenna arrangement is stable, the extraction of the signal extraction unit 140 can be performed with higher accuracy.

  Further, in the case of the density calculation unit 142 of the in-vehicle terminal 107 shown in FIG. 8, the density (congestion degree) of an object such as a person in an area having a radius of 10 meters may be calculated in the same manner, or wider. Measurement may be performed in the area, and a result obtained by collecting a plurality of areas having a radius of 10 meters may be transmitted to the congestion information management server 102.

  In the density (congestion degree) calculation method described above, the closer to the center of the area, the smaller the actual area of the unit area than the unit area around the area. Therefore, the density (congestion degree) corresponding to the actual area may be calculated by multiplying the area weight for each unit region where “1” or “0” is determined.

  Needless to say, the method of calculating the fan-shaped area forming each unit region is not particularly described. It is only necessary to calculate the areas of these fan shapes once and create a weight list for the area of each unit region. Therefore, the calculation of the density (congestion degree) with respect to the actual area does not particularly burden the portable terminal 105 and the in-vehicle terminal 107.

  FIG. 14 shows the processing of the congestion information management server when the mobile terminal or the in-vehicle terminal uploads the measurement data. This will be described with reference to FIGS.

  The control unit 133 of the congestion information management server 102 waits for measurement data to be transmitted from the mobile terminal 105 or the in-vehicle terminal 107 (step S251). When the measurement data is transmitted (Y), the date and time measured by the mobile terminal 105 or the in-vehicle terminal 107 and information on the latitude and longitude of the measurement point are extracted from this data (step S252). Then, the radar measurement result (density information) in the measurement data is stored in the storage area corresponding to the supplementary information in the congestion information database 158 (step S253), and the process of step S251 is performed in order to wait for reception of the next measurement data. Return to (Return).

  In addition, the process which sends the point as a thanks to the portable terminal 105 or the vehicle-mounted terminal 107 which transmitted measurement data when the process of step S253 is complete | finished may be added. In this case, after the measurement data is transmitted to the congestion information management server 102 in step S215 in FIG. 10, processing is performed in which the portable terminal 105 (or the in-vehicle terminal 107) waits for reception of points from the congestion information management server 102. The communication disconnection process of step S210 is performed after receiving the points.

  FIG. 15 shows a part of measurement data received by the reception unit of the congestion information management server. This will be described with reference to FIG.

  The congestion information management server 102 sequentially receives measurement data from the mobile terminal 105 or the in-vehicle terminal 107. The measurement data includes the measurement date and time, the latitude and longitude that are the center of the measured area, and the density (congestion degree) of the measurement results. Here, a state is shown in which a small amount of measurement data is received per hour, but if the number of portable terminals 105 and in-vehicle terminals 107 that transmit measurement data is large, a large amount of measurement data is collected.

  FIG. 16 shows a state of processing for the operator of the communication terminal to display the congestion status of a desired area. In the congestion information display system 100 shown in FIG. 6, an operator of a communication terminal such as the user 104 of the mobile terminal 105 can specify the location and date and know the congestion status of the area. Here, a case where the user 104 of the mobile terminal 105 acquires the congestion status will be described as an example. This will be described with reference to FIGS.

  Based on the operation of the input unit 123 by the user 104, the control unit 113 connects the portable terminal 105 to the congestion information management server 102 (step S271). Thereafter, a request for a reference range input screen regarding the congestion state is transmitted from the wireless communication control unit 115 to the congestion information management server 102 (step S272). Prior to the process of step S272, a member authentication process may be performed.

  Thereafter, the wireless communication control unit 115 waits for the reference range input screen to be received from the congestion information management server 102 (step S273). When the reference range input screen is received from the congestion information management server 102 (Y), the reference range input screen is displayed on the display unit 124 (step S274).

  FIG. 17 shows an example of a reference range input screen. This will be described with reference to FIG.

  A reference range input screen 181 is displayed on the display unit 124. The user 104 can input the latitude, longitude, and reference time of the area where the user wants to grasp the congestion status from the input unit 123 using the reference range input screen 181. An example of input is shown below.

Latitude reference range: 35.6743737 degrees to 35.680664 degrees Longitude reference range: 139.761329 degrees to 139.776972 degrees Time reference range: within 1 hour

  Instead of inputting latitude and longitude numerically, the user 104 can open a window for displaying a map on the display unit 124 by pressing the designation button 182 on the map, and use this to specify an area for which the congestion situation is to be grasped. Is possible. The reference time can be input by automatically selecting the latest date and time by selecting a radio button.

  The reference range input screen 181 is provided with a send button 183 and a cancel button 184. When the user 104 operates the transmission button 183 (step S275 in FIG. 16: Y), data about the input reference range is transmitted to the congestion information management server 102 (step S276). On the other hand, when the user 104 clicks the cancel button 184 to stop the transmission of data for the reference range (step S275: N, step S277: Y), the process for acquiring the congestion status is not completed. A series of processing ends (end).

  On the other hand, when the data about the reference range is transmitted in step S276, the control unit 113 waits for the congestion status image to be received from the congestion information management server 102 (step S278). When the congestion status image is received (Y), the control unit 113 stores it in a specific area of the information storage unit 121 (step S279). Then, this image is displayed on the display unit 124 (step S280), and a series of processing ends (end).

  FIG. 18 shows how the congestion status image is transmitted by the congestion information management server. This will be described with reference to FIGS. 6, 9 and 16. Here, the case where the portable terminal 105 shown in FIG. 7 makes a request for displaying the congestion status to the congestion information management server 102 will be described, but the control itself is also performed when the in-vehicle terminal 107 makes a similar request. It does n’t change.

  The congestion information management server 102 waits for reception of a request for a reference range input screen (step S291). When a request for a reference range input screen is sent from the portable terminal 105 (Y), the transmission unit 155 transmits data for displaying the reference range input screen to the request destination (step S292). And it waits for portable terminal 105 to transmit data about a reference range (Step S293).

  When the reception unit 156 of the congestion information management server 102 receives the data about the reference range (step S293: Y), the control unit 153 searches the congestion information database 158 for the density information and map data of the reference range designated by this data. (Step S294). The control unit 153 passes the acquired density information and map data of these reference ranges to the image generation unit 159. Based on this, the image generation unit 159 generates a congestion status image for the reference range (step S295). This will be described in detail next. The transmission unit 155 transmits the generated congestion status image to the mobile terminal 105 shown in FIG. 7 (step S296), and ends a series of processing (end).

  FIG. 19 shows the state of the image generation processing of the image generation unit described in step S295 of FIG. This will be described with reference to FIG.

  First, the image generation unit 159 expands the map data of the reference range to a specific area in the memory 152 (step S311). In this example, it is assumed that the user 104 shown in FIG.

  FIG. 20 shows an image of map data developed in a specific area of the memory of the congestion information management server. This will be described with reference to FIG. In the memory 152A, a map around Marunouchi in Tokyo designated as the reference range is displayed.

  Returning to FIG. 19, the description will be continued. Next, the image generation unit 159 arranges the density data of the reference range acquired from the congestion information database 158 at the corresponding position in the map data while color-coding each according to the density (step S312). Thereby, the image generation process by the image generation unit 159 ends (END).

  FIG. 21 shows an image of a map in which the density data of each measurement point is arranged by the process of step S312 of FIG. However, since FIG. 21 is represented as a black and white image for the convenience of drawing, in this example, there are three types of graphics to be displayed instead of color coding with three levels of density. The closer the measurement points, the closer the figures at those measurement points. In this way, it is necessary to pay attention to the fact that the actual congestion situation is represented by the type of figure in the image of this map, rather than the objects that are in close proximity to each figure being mixed. .

  Accordingly, in step S280 in FIG. 16, an image similar to the image shown in FIG. 19 is displayed on the communication terminal. The operator of the communication terminal displays the image shown in FIG. 11, and the premises of Yurakucho station is colored in red, so that the density is in the range of 100 to 81% and is very mixed. You can know the facts immediately. Also, by changing the date and time of measurement at the same place, it is possible to easily know changes in busy days and times.

  In the map image shown in FIG. 21, an area with a density of 80 to 61 percent is colored yellow, and an area with a density of 60 to 41 percent is colored green. If the reference range of the map is expanded and the surrounding areas are displayed at once, it is possible to easily determine whether or not the Marunouchi area is more crowded than the other areas. In addition, with respect to the road on which the vehicle travels, it is possible to easily select a route for reaching the destination while avoiding a place where the traffic jam occurs.

  As described above, according to the present embodiment, the congestion state is collected for each measurement point, so the congestion state is displayed on the map regardless of the number of communication terminals performing measurement and the bias of these measurement points. Can be represented. Of course, by placing fixed simple radars at measurement points such as stations, museums, movie theaters, restaurants, etc. that many people would like to know, by shifting the current congestion situation and time You can be sure of changes in congestion.

  Moreover, in the present embodiment, points can be obtained each time a member as a user of the mobile terminal 105 or the in-vehicle terminal 107 transmits measurement data to the congestion information management server 102. As a result, the member actively transmits the measurement data to the congestion information management server 102. In addition, an increase in points can be set for a person who transmits measurement data to the congestion information management server 102 at an appropriate time and place. Therefore, the congestion information display system 100 according to the present embodiment can provide effective data to the user without incurring a large amount of operation costs.

  <Deformability of invention>

  In the embodiment described above, the operator of the communication terminal such as the user 104 of the portable terminal 105 measures the congestion status using the radar at an arbitrary time. The measurement may be performed at regular time intervals. Alternatively, the congestion information management server 102 may send request data to the portable terminal 105 or the in-vehicle terminal 107 that performs measurement, and request the measurement at a desired time. Further, the congestion information management server 102 sequentially checks the location information of these communication terminals of the members, and transmits request data for measuring the congestion status to the communication terminals existing at the place where measurement is desired. Also good.

  In the embodiment, the density data in the area having a radius of 10 meters is measured. However, it is also effective to arbitrarily adjust the area to be measured. For example, it is possible to exclude buildings larger than this from the detection range by changing the effective distance of the radar to the length of the vehicle width when grasping the congestion situation on the road. Thereby, the density (congestion degree) of objects such as vehicles on the road can be acquired more accurately.

  Furthermore, in the embodiment, the radar is used to grasp the congestion situation of objects such as people and vehicles around the measurement point. However, the camera provided in the communication terminal takes a photograph of the periphery of the measurement point. Can be transmitted to the congestion information management server, and image analysis can be performed to grasp the density (congestion degree) of surrounding objects.

  In this case, for example, after the photographed photograph is binarized with a predetermined threshold value and divided into an object and other parts, the area of the part determined to be an object may be integrated to calculate the ratio of the entire area. In addition, it is possible to discriminate between moving objects in the object and stationary objects such as buildings by taking pictures with different times, such as several hours ago, and comparing them with this. Thus, only the moving object can be extracted as an object to be determined for the congestion situation. Of course, it is also effective to use an infrared camera together or to refer to a map of the parking area of the vehicle.

  In the case of this modification, since the photograph is taken, the rotation control of the antenna for outputting the electromagnetic wave in each direction becomes unnecessary. Each communication terminal transmits information indicating the current position of the focal length of the camera and the height at the time of shooting from the ground as supplementary information to the congestion information management server together with position information and shooting date / time information when sending the camera image. do it.

  Furthermore, although the millimeter wave radar is used in the embodiment, it is needless to say that other electromagnetic waves such as an infrared radar may be used.
