  In addition, the traffic regulation information processing unit 22 acquires, for example, 0.7, 0.8, and 0.9 from the vehicle branch information as the probabilities that the vehicles flow into the road link L4 from the road links L5, L6, and L7.

  In addition, the traffic regulation information processing unit 22 acquires, for example, 0.6 and 0.7 from the vehicle branch information as probabilities that vehicles flow into the road link L7 from the road links L8 and L9.

  The traffic regulation information processing unit 22 calculates, for example, the probability of a vehicle flowing into the regulation link L1 from the road link L5 via the road link L4 to 0.63 by multiplying 0.7 by 0.9.

  Similarly, the traffic regulation information processing unit 22 calculates the probabilities that vehicles will flow from the road links L6 and L7 to the regulation link L1 via the road link L4 as 0.72 and 0.81, respectively.

  Similarly, the traffic regulation information processing unit 22 calculates the probabilities that vehicles will flow from the road links L8 and L9 to the regulation link L1 via the road links L7 and L4 as 0.486 and 0.567, respectively.

  Similarly, the traffic regulation information processing unit 22 calculates a probability that a vehicle flows into the regulation link L1 from the road links L10 to L23 via one or a plurality of road links. Each probability calculated at this time is smaller than 0.5, for example.

  The traffic regulation information processing unit 22 determines, for example, an area including the road links L2 to L7 and L9 having the calculated probability of 0.5 or more and the regulation link L1 as the target area A1.

  In addition, the traffic regulation information processing unit 22 acquires the degree of congestion of vehicles in the same day type and the same time zone as the suppression time zone CP in the determined target area A1 from the traffic congestion information.

  Then, the traffic regulation information processing unit 22 determines whether or not a traffic jam occurs in the suppression area CA based on the congestion degree and the content of the traffic regulation information in the acquired target area A1.

  For example, when it is determined that no traffic congestion occurs in the suppression area CA, the traffic regulation information processing unit 22 recognizes that there is no need to perform traffic flow control, and continues until new traffic regulation information is received from the traffic regulation information acquisition unit 21. stand by.

  On the other hand, for example, when it is determined that traffic congestion occurs in the suppression area CA, the traffic regulation information processing unit 22 recognizes that it is necessary to perform traffic flow control, and sets time zone information indicating the suppression time zone CP and the target area A1. , The area ID indicating the restriction link ID, the restriction direction CD, and the position of the suppression area CA are created, and the created time zone information and area information are output to the setting unit 23 and the extraction unit 24.

  Referring to FIG. 3 again, setting unit 23 determines, based on, for example, the number TN of vehicles traveled when traffic suppression is not performed in suppression area CA and the content of planned traffic suppression, suppression time zone CP , A target Tgt related to the number of vehicles to be driven in the target area A1 is set.

  More specifically, when receiving the traffic regulation information from the traffic regulation information acquisition unit 21, the setting unit 23 recognizes the contents of the planned traffic suppression based on the received traffic regulation information.

  Further, upon receiving the time zone information and the area information from the traffic regulation information processing unit 22, the setting unit 23, based on the received time zone information and area information, sets the restriction time zone CP and the restriction link L1 where the restriction area CA is located. And the control direction CD is recognized.

  In addition, the setting unit 23 acquires the traveling number information from the link information database 121 and, based on the acquired traveling number information, for example, sets the restriction link L1 in the restriction direction in the same day type and the same time period as the suppression time period CP. The number of vehicles traveling to the CD is acquired as the traveling number TN. In this example, the setting unit 23 acquires, for example, 120 vehicles as the number of traveling vehicles TN.

  For example, when the content of traffic suppression is to reduce two lanes to one lane, the setting unit 23 estimates the reduced number of vehicles 1 to be 倍 times the number of traveling vehicles TN, that is, 60 vehicles. Then, the setting unit 23 sets the target Tgt relating to the reduced number to 50 to 70 units. Although the setting unit 23 sets the target Tgt having a width, the target Tgt may be set to a fixed value such as 60 units. The setting unit 23 may determine the target Tgt using a probability or a ratio instead of the number.

  The setting unit 23 creates target information indicating the set target Tgt, and outputs the created target information to the communication processing unit 25.

  FIG. 5 is a diagram showing an example of a map around the target area set by the traffic flow control device according to the first embodiment of the present invention.

  Referring to FIG. 5, extraction unit 24 extracts a target vehicle that is vehicle 1 that is predicted to travel in target area A1 during suppression time zone CP.

  For example, the extraction unit 24 specifies the upstream area UA and the downstream area LA based on the suppression area CA, and selects the target area A1 from the vehicle 1 traveling from the specified upstream area UA to the downstream area LA in the suppression time zone. A target vehicle predicted to travel to the CP is extracted.

  More specifically, for example, based on trajectory information indicating a past traveling route of the vehicle 1, the extraction unit 24 selects the target area A1 from the vehicle 1 traveling from the upstream area UA to the downstream area LA in a suppression time zone. The target vehicle traveling to the CP is predicted. In other words, for example, based on the trajectory information, the extraction unit 24 extracts, from the vehicles 1 traveling from the upstream area UA to the downstream area LA, a target vehicle predicted to travel in the target area A1 during the suppression time zone CP. I do.

  When the extraction unit 24 receives the time zone information and the area information from the traffic regulation information processing unit 22, based on the received time zone information and area information, the restriction time zone CP, the restriction link L1 where the restriction area CA is located, and the restriction The direction CD and the range of the target area A1 are recognized.

  In addition, the extraction unit 24 acquires road link information from the link information database 121, and recognizes the connection relationship of each road link around the regulation link L1 based on the acquired road link information.

  For example, as illustrated in FIGS. 4 and 5, the extraction unit 24 sets a straight line that passes through the suppression area CA and is perpendicular to the direction in which the road extends in the suppression area CA as the boundary line VL. The extraction unit 24 specifies, for example, an upstream area and a downstream area with respect to the set boundary line VL as an upstream area UA and a downstream area LA, respectively.

  Note that the extraction unit 24 determines, based on the trajectory information held in the trajectory information database 123, an area including the departure place and an area including the arrival place of the vehicle 1 passing from the upstream to the downstream in the suppression area CA, respectively. It may be specified as a UA and a downstream area LA.

  Further, when there is a geographical condition such as a mountain or a river that restricts the road, the extraction unit 24 specifies the upstream area UA and the downstream area LA by setting a boundary line VL along the mountain or the river. May be.

  The extraction unit 24 acquires the trajectory information from the trajectory information database 123, and based on the acquired trajectory information, the vehicle 1 that has entered the downstream area LA from the upstream area UA in the same day type and the same time zone as the suppression time zone CP. (Hereinafter, also referred to as an approaching vehicle).

  In this example, as illustrated in FIG. 5, the extraction unit 24 determines that the vehicle IDs having passed the trajectories Tr1, Tr2, Tr3, Tr4, and Tr5 are 1 to 100, 101 to 200, 201 to 300, 301 to 400, Vehicles 401 to 500 are specified as entering vehicles. Here, the terminal IDs corresponding to the vehicles 1 having the vehicle IDs 1 to 500 are, for example, 1 to 500, respectively.

  Then, the extracting unit 24 extracts, as the target vehicle, the vehicle 1 that has traveled in the target area A1 in the same day type and the same time period as the suppression time zone CP among the specified approaching vehicles.

  More specifically, in the same day type and the same time zone as the suppression time zone CP, the extraction unit 24 includes, for example, the vehicle 1 that has passed the target area A1, the vehicle 1 that has entered the target area A1, but has not passed, and The vehicle 1 coming out of the target area A1 is predicted to run in the target area A1 during the suppression time zone CP, and the vehicle 1 is extracted as a target vehicle.

  In this example, as illustrated in FIG. 5, the extraction unit 24 specifies the vehicles 1 having the vehicle IDs of 1 to 100, 101 to 200, and 201 to 300 that have passed the trajectories Tr1, Tr2, and Tr3 as target vehicles. .

  The extraction unit 24 outputs the extracted vehicle ID of the target vehicle, the trajectory corresponding to the vehicle ID, time zone information, and area information to the communication processing unit 25.

  The communication processing unit 25 notifies the terminal device 202 corresponding to the target vehicle of request information indicating requesting not to travel in the target area A1 during the suppression time zone CP.

  Here, the request information indicates, for example, that the vehicle does not pass through the target area A1 during the suppression time zone CP, that public transportation is used, and that the vehicle passes through the target area A1 during a time period different from the suppression time period CP. . In other words, the request information indicates that the request area does not pass through the target area A1 in a time zone overlapping the suppression time zone CP, that the request information uses public transportation, and that the request information passes through the target area A1 in a time zone that does not overlap with the suppression time zone CP. To the effect.

  More specifically, when the communication processing unit 25 receives the vehicle ID of the target vehicle, the trajectory corresponding to the vehicle ID, and the time zone information and the area information from the extraction unit 24, the communication processing unit 25 performs the processing based on the received time zone information and the area information. Thus, the control unit recognizes the suppression time zone CP, the regulation link L1 where the suppression area CA is located, the regulation direction CD, and the range of the target area A1.

  When receiving the target information from the setting unit 23, the communication processing unit 25 recognizes the target Tgt from the received target information.

  When the communication processing unit 25 recognizes that the target Tgt is, for example, 50 to 70 vehicles, the vehicle IDs of the target vehicles for the median 60 vehicles from among the vehicle IDs of the target vehicles received from the extraction unit 24. Is selected as the transmission target of the request information.

  Then, the communication processing unit 25 acquires the departure place and the arrival place of the target vehicle (hereinafter, also referred to as a selected vehicle) corresponding to the selected vehicle ID from the locus corresponding to the selected vehicle ID.

  The communication processing unit 25 acquires the road link information from the link information database 121 and, based on the acquired road link information and the departure place and the arrival place of the selected vehicle, without passing through the target area A1 from the departure place. A connection configuration of road links that can reach the destination is derived.

  Then, in the suppression time period CP, the communication processing unit 25 creates a request to use a route based on the derived connection configuration and substitute link use request information indicating a locus corresponding to the vehicle ID of the selected vehicle.

  Further, the communication processing unit 25 acquires public transport information from the public transport information database 125, and performs public transport from the departure place based on the acquired public transport information and the departure place and arrival place of the selected vehicle. A route that can be reached to the destination using the institution is derived.

  Then, the communication processing unit 25 creates public transportation use request information indicating that the use of the derived route is requested in the suppression time zone CP.

  The communication processing unit 25 creates substitute link use request information and public transport use request information for each vehicle ID of the selected vehicle.

  In addition, the communication processing unit 25 creates time difference travel request information indicating that a request is made to run the target area A1 in a time zone different from the suppression time zone CP.

  Further, the communication processing unit 25 acquires the driver information from the driver information database 124 and, based on the acquired driver information and the vehicle ID of the selected vehicle, determines the terminal ID of the terminal device 202 corresponding to the vehicle ID of the selected vehicle. To get.

  Then, the communication processing unit 25 creates and holds ID information indicating the correspondence between the vehicle ID of the selected vehicle and the corresponding terminal ID.

  The communication processing unit 25 transmits the created alternative link use request information, the public transport use request information and the time difference travel request information, the time zone information and the area information, for example, one day before the day including the suppression time zone CP, to the terminal ID. The address is transmitted to the terminal device 202 as a destination. At this time, the communication processing unit 25 transmits the substitute link use request information and the public transport use request information of the vehicle ID corresponding to the terminal ID.

  Further, the communication processing unit 25 creates the transmitted request information including the alternative link use request information, the public transportation use request information and the time difference travel request information, and the time zone information and the area information, and transmits the generated transmitted request information to the terminal. It is stored in the transmitted request information database 126 in association with the ID and the vehicle ID.

  The receiving unit 42 receives an operation by the driver, and outputs operation information indicating the content of the received operation to the processing unit 43.

  Upon receiving the operation information from the reception unit 42, the processing unit 43 creates a screen Scr3 based on the public transportation use request information and performs control to display the created screen Scr3 on the display unit 44 according to the received operation information. .

  Thereby, the driver can confirm the transfer and the required time when using public transportation.

  Referring to FIG. 7 again, when the driver travels the alternative route in the suppression time zone CP, after selecting the radio button Rb1, the driver taps the button Bt1. In addition, when using the public transportation in the suppression time zone CP, the driver selects the radio button Rb2 and then taps the button Bt1. In addition, when the driver travels in the target area A1 in a time zone different from the suppression time zone CP, after selecting the radio button Rb3, the driver taps the button Bt1. In addition, when traveling on a normal route in the suppression time zone CP, the driver selects the radio button Rb4 and then taps the button Bt1. When the driver does not go out on the day on which the regulation is performed, the driver selects the radio button Rb5 and then taps the button Bt1.

  Referring to FIG. 6 again, accepting unit 42 accepts an operation by the driver and outputs operation information indicating the accepted operation content to processing unit 43.

  When receiving the operation information from the reception unit 42, the processing unit 43 creates response information including the content corresponding to the selection result of the radio buttons Rb1 to Rb5 indicated by the received operation information.

  More specifically, when the operation information indicates that the radio button Rb1 has been selected by the driver as an example of the positive response information indicating a positive response to the request information, the processing unit 43 determines that the driver has The acknowledgment information PR1 indicating that the driver intends to drive the alternative route is created.

  In addition, when the operation information indicates that the radio button Rb2 is selected by the driver as an example of the acknowledgment information, the processing unit 43 indicates that the driver intends to use public transportation in the suppression time zone CP. The acknowledgment information PR2 is created.

  When the operation information indicates that the radio button Rb3 is selected by the driver as an example of the acknowledgment information, the processing unit 43 intends that the driver travels in the target area A1 in a time zone different from the suppression time zone CP. Is generated as acknowledgment information PR3.

  When the operation information indicates that the radio button Rb4 has been selected by the driver as an example of the negative response information indicating a negative response to the request information, the processing unit 43 determines that the driver performs the normal route in the suppression time zone CP.

  The transmitting unit 45 transmits response information to the request information received by the receiving unit 41. Specifically, when receiving any one of the positive response information PR1 to PR3, the negative response information, and the neutral response information from the processing unit 43, the transmitting unit 45 transmits the received response information together with its own terminal ID to the traffic flow control. Transmit to the device 101.

[Structure 2 of traffic flow control device]
Referring to FIG. 3 again, communication processing unit 25 acquires response information from terminal device 202 to the request information, for example, as a response acquisition unit. In addition, the communication processing unit 25 determines whether to notify the request information to another terminal device 202 based on the target Tgt set by the setting unit 23 and the acquired response information, for example.

  More specifically, when receiving the response information and the terminal ID from the terminal device 202, the communication processing unit 25 acquires a vehicle ID corresponding to the terminal ID based on the received terminal ID and the held ID information.

  The communication processing unit 25 confirms the content of each response information received until a predetermined time has elapsed since the transmission of the request information, and thereby determines the number of acknowledgment information PR1, PR2, PR3 included in each response information. Count.

  When the counted number is less than the lower limit of the target Tgt of 50, the communication processing unit 25 determines to transmit the request information to the terminal device 202 corresponding to the target vehicle other than the selected vehicle.

  More specifically, the communication processing unit 25 further selects, from the target vehicles excluding the selected vehicles, the number of target vehicles obtained by subtracting the target number from 60, which is the median of the target Tgt.

  Then, the communication processing unit 25 transmits the alternative link use request information, the public transport use request information and the time difference travel request information, and the time zone information and the area information, with the terminal ID corresponding to the selected target vehicle as the destination.

  On the other hand, when the counted number is equal to or more than the lower limit of the target Tgt, that is, 50 or more, the communication processing unit 25 determines not to transmit the request information to the terminal device 202 corresponding to the target vehicle other than the selected vehicle.

  The communication processing unit 25 outputs the positive response information, the negative response information or the neutral response information, the time zone information and the area information, the terminal ID and the vehicle ID to the result processing unit 28, and outputs the positive response information, the negative response information or the neutral response information. The response information and the terminal ID are output to the calculation unit 26.

  The calculation unit 26 calculates a price based on the contents of the response information acquired by the communication processing unit 25, for example.

  Specifically, upon receiving the acknowledgment information and the terminal ID from the communication processing unit 25, the calculation unit 26 calculates a price according to the content of the acknowledgment information.

  More specifically, when receiving the acknowledgment information PR1, PR2, PR3 and the terminal ID from the communication processing unit 25, the calculation unit 26 calculates the incentives P1, P2, and P3 as compensation.

  Here, the incentives P1, P2, and P3 are coupons or the like that can receive a discount on the cost of continuous inspection of automobiles, a discount on tolls on toll roads, or a discount on merchandise prices at stores.

  On the other hand, when receiving the negative response information or the neutral response information and the terminal ID from the communication processing unit 25, the calculation unit 26 calculates zero as a price.

  The calculation unit 26 outputs the calculated price and the terminal ID to the result processing unit 28.

  When the result processing unit 28 receives the neutral response information, the time zone information and the area information, and the terminal ID and the vehicle ID from the communication processing unit 25, as shown in FIG. The received response information is stored in the received response information database 127 in association with the ID and the vehicle ID.

  Further, when the result processing unit 28 receives the negative response information, the time zone information and the area information, and the terminal ID and the vehicle ID from the communication processing unit 25, as shown in FIG. In the received response information database 127 in association with the terminal ID and the vehicle ID.

  Further, when the result processing unit 28 receives the acknowledgment information, the time zone information and the area information, and the terminal ID and the vehicle ID from the communication processing unit 25, the suppressed time zone CP indicated by the received time zone information or the suppressed time The result of the driver corresponding to the terminal ID in the time period based on the band CP is acquired, and it is confirmed whether or not the acquired result and the content of the acknowledgment information are consistent.

  Then, the result processing unit 28 creates result information indicating the confirmation result, and accumulates the created result information, the positive response information, and the time zone information in the received response information database 127 in association with the terminal ID and the vehicle ID.

  More specifically, upon receiving the acknowledgment information PR1, the time zone information and the area information, the terminal ID and the vehicle ID from the communication processing unit 25, the performance processing unit 28 waits until the suppression time zone CP elapses.

  Then, when the suppression time zone CP elapses, the performance processing unit 28 acquires probe data of the target vehicle having the vehicle ID in the suppression time zone CP from the trajectory information database 123.

  The performance processing unit 28 confirms whether or not the driver has traveled on the alternative route in the suppression time zone CP based on the acquired probe data and the area information.

  When the result processing unit 28 confirms that the driver has traveled the alternative route in the suppression time zone CP, the result processing unit 28 creates result information indicating that there is consistency, and as shown in FIG. PR1 and time zone information are stored in the received response information database 127 in association with the terminal ID and the vehicle ID.

  In this case, the performance processing unit 28 gives the incentive P1 calculated by the calculation unit 26 to the corresponding driver.

  On the other hand, when confirming that the driver did not travel on the alternative route during the suppression time zone CP, the performance processing unit 28 creates performance information indicating that there is no consistency, and as illustrated in FIG. The affirmative response information PR1 and the time zone information are stored in the received response information database 127 in association with the terminal ID and the vehicle ID.

  In this case, the result processing unit 28 does not give the incentive P1 to the corresponding driver. The performance processing unit 28 may give a penalty to the corresponding driver. The content of the penalty is, for example, stopping delivery of request information to a driver who has performed a predetermined number of actions against the request after responding positively to the request.

  Further, upon receiving the acknowledgment information PR2, the time zone information and the area information, the terminal ID and the vehicle ID from the communication processing unit 25, the performance processing unit 28 waits until the suppression time zone CP elapses.

  Then, at the timing after the suppression time zone CP elapses, the result processing unit 28 receives, for example, the provision of the history information indicating the history using the public transportation period recorded on the IC card from the driver. Based on the history information, it is confirmed whether or not the driver used the public transportation period in the suppression time zone CP.

  Note that when the terminal device 202 can acquire its own coordinates based on radio waves transmitted from GPS satellites, the result processing unit 28 transmits, for example, coordinate information indicating the coordinates of the terminal device 202 in the suppression time zone CP. It may be obtained from the terminal device 202 and, based on the obtained coordinate information, determine whether or not the driver has used the public transportation period in the suppression time zone CP.

  When confirming that the driver has used the public transportation period in the suppression time zone CP, the result processing unit 28 creates result information indicating that there is consistency, and as shown in FIG. The information PR2 and the time zone information are stored in the received response information database 127 in association with the terminal ID and the vehicle ID.

  In this case, the performance processing unit 28 gives the incentive P2 calculated by the calculation unit 26 to the corresponding driver.

  On the other hand, when the result processing unit 28 confirms that the driver did not use the public transportation period in the suppression time zone CP, the result processing unit 28 creates result information indicating that there is no consistency, and as shown in FIG. The information, the positive response information PR2, and the time zone information are stored in the received response information database 127 in association with the terminal ID and the vehicle ID.

  In this case, the result processing unit 28 does not give the incentive P2 to the corresponding driver. Note that the performance processing unit 28 may give the above driver a penalty.

  Further, upon receiving the acknowledgment information PR3, the time zone information and the area information, the terminal ID and the vehicle ID from the communication processing unit 25, the performance processing unit 28 performs a predetermined time, for example, three hours before the start timing of the suppression time zone CP. A timing ts is set for a predetermined time, for example, 3 hours after the timing ts and the end timing of the suppression time zone CP.

  Then, when the set timing te elapses, the performance processing unit 28 acquires probe data from the locus information database 123 after the timing ts of the target vehicle having the vehicle ID and before the timing te.

  The performance processing unit 28 confirms a time zone during which the driver has traveled in the target area A1, based on the acquired probe data and the area information.

  The performance processing unit 28 determines the specified time that is a timing after the timing ts and before the start timing of the suppression time zone CP, or a timing after the end timing of the suppression time zone CP and before the timing te. When it is confirmed that the driver has traveled in the target area A1 in the belt, the following processing is performed.

  That is, the performance processing unit 28 generates performance information indicating that there is consistency, and receives the generated performance information, the acknowledgment information PR3, and the time zone information in association with the terminal ID and the vehicle ID, as shown in FIG. Is stored in the completed response information database 127.

  In this case, the performance processing unit 28 gives the incentive P3 calculated by the calculation unit 26 to the corresponding driver.

  On the other hand, when confirming that the driver did not travel in the target area A1 in the designated time zone, or when confirming that the driver ran in the target area A1 in the suppression time zone CP, Perform processing.

  That is, the performance processing unit 28 generates performance information indicating that there is no consistency, and receives the generated performance information, acknowledgment information PR3, and time zone information in association with the terminal ID and the vehicle ID, as shown in FIG. Is stored in the completed response information database 127.

  In this case, the result processing unit 28 does not give the incentive P3 to the corresponding driver. Note that the performance processing unit 28 may give the above-mentioned penalty to the corresponding driver.

Each device in the traffic flow control system 301 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads out a program including a part or all of each step of the following sequence diagram or flowchart from a memory (not shown). Execute. Each of the programs of the plurality of devices can be externally installed. The programs of the plurality of devices are distributed while being stored in a recording medium.

  FIG. 10 is a flowchart that defines an operation procedure when the traffic flow control device according to the first embodiment of the present invention processes traffic regulation information.

  Referring to FIG. 10, first, traffic flow control device 101 determines whether the transmission timing of the alternative link use request information, the public transport use request information and the time difference travel request information, the time zone information and the area information has arrived, or The process waits until the timing of collecting the regulation information comes (NO in step S102 and NO in step S106).

  Next, when the traffic regulation information collection timing comes (YES in step S106), the traffic flow control device 101 acquires one or more types of traffic regulation information from the distribution server 151 via the Internet 10 (step S108).

  Next, when the content of the acquired traffic regulation information has been acquired in the past (NO in step S110), the traffic flow control device 101 arrives at the transmission timing or newly collects the traffic regulation information. It waits until it arrives (NO in step S102 and NO in step S106).

  On the other hand, when the content of the acquired traffic regulation information is new (YES in step S110), the traffic flow control device 101 determines the target area A1 and acquires the suppression time zone CP based on the new traffic regulation information. (Step S112).

  Next, when it is determined that traffic congestion occurs in the suppression area CA in the suppression time zone CP (YES in step S114), the traffic flow control device 101 recognizes that it is necessary to perform traffic flow control, and determines the target area A1. The vehicle ID of the target vehicle which is the vehicle 1 predicted to run during the suppression time zone CP is extracted (step S116).

  Next, the traffic flow control device 101 creates and stores alternative link use request information, public transport use request information, and time difference travel request information (step S118).

  Next, the traffic flow control device 101 sets the target area A1 in the suppression time zone CP based on the number TN of vehicles running when traffic suppression is not performed in the suppression area CA and the content of the planned traffic suppression. A target Tgt of the number of vehicles to be reduced is set (step S120).

  Next, the traffic flow control device 101 checks whether or not there is unprocessed traffic regulation information among the traffic regulation information having new contents (step S122).

  On the other hand, when the traffic flow control device 101 determines that there is no traffic congestion in the suppression area CA in the suppression time zone CP (NO in step S114), the traffic flow control device 101 recognizes that there is no need to perform the traffic flow control, and renews the contents. It is checked whether there is unprocessed traffic regulation information among the traffic regulation information (step S122).

  If the traffic flow control device 101 determines that there is unprocessed traffic regulation information (YES in step S122), the traffic flow control device 101 determines the corresponding target area A1 based on the unprocessed traffic regulation information and sets the corresponding suppression time zone. A CP is acquired (Step S112).

  On the other hand, when it is confirmed that there is no unprocessed traffic regulation information (NO in step S122), the traffic flow control device 101 selects a number of vehicle IDs corresponding to the target Tgt from the extracted vehicle IDs (step S124). ).

  Next, the traffic flow control device 101 acquires a terminal ID corresponding to the selected vehicle ID (step S126).

  Next, the traffic flow control device 101 waits until the transmission timing has arrived or the traffic regulation information collection timing has newly arrived (NO in step S102 and NO in step S106).

  On the other hand, when the transmission timing comes (YES in step S102), the traffic flow control device 101 sets the obtained terminal ID as a destination, and uses the alternative link use request information, the public transport use request information, the time difference travel request information, and the time zone information. And the area information is transmitted to the terminal device 202 (step S104).

  Next, the traffic flow control device 101 waits until the transmission timing has arrived or the traffic regulation information collection timing has newly arrived (NO in step S102 and NO in step S106).

  Note that the order of steps S116 and S118 and S120 is not limited to the above, and the order may be changed.

  FIG. 11 is a flowchart that defines an operation procedure when the terminal device according to the first embodiment of the present invention processes request information.

  Referring to FIG. 11, first, terminal device 202 waits until alternative link use request information, public transport use request information and time difference travel request information, and time zone information and area information are received from traffic flow control device 101. (NO in step S202).

  Next, when receiving the alternative link use request information, the public transportation use request information and the time difference travel request information, and the time zone information and the area information from the traffic flow control device 101 (YES in step S202), the terminal device 202 receives the information. A screen Scr1 shown in FIG. 7 is displayed on the display unit 44 based on these pieces of information (step S204).

  Next, the terminal device 202 waits until the button Bt1 is tapped by the driver (NO in step S206).

  Next, when button Bt1 is tapped by the driver (YES in step S206), terminal device 202 creates response information including content corresponding to the selection result of radio buttons Rb1 to Rb5 (step S208).

  FIG. 12 is a flowchart that defines an operation procedure when the traffic flow control device according to the first embodiment of the present invention determines whether to transmit request information to another terminal device.

  Referring to FIG. 12, first, traffic flow control device 101 initializes count value Cnt indicating the number of acknowledgment information to zero (step S302).

  Next, the traffic flow control device 101 waits until acknowledgment information is received until a predetermined time elapses after transmitting the request information (NO in step S304 and NO in step S306).

  Next, when the traffic flow control device 101 receives the acknowledgment information until a predetermined time elapses after transmitting the request information (NO in step S304 and YES in step S306), it increments the count value Cnt (step S306). S308).

  On the other hand, when a predetermined time has elapsed after transmitting the request information (YES in step S304), traffic flow control device 101 compares count value Cnt with lower limit value Min, which is the lower limit of target Tgt (step S310).

  When the count value Cnt is less than the lower limit value Min (YES in step S310), the traffic flow control device 101 calculates an additional value Red by subtracting the count value Cnt from the median value Med of the target Tgt (step S312).

  Next, the traffic flow control device 101 further selects the number of target vehicles corresponding to the additional value Red from the target vehicles excluding the selected vehicle (step S314).

  Next, the traffic flow control device 101 transmits the request information with the terminal ID corresponding to the selected target vehicle as a destination (step S316).

  Next, the traffic flow control device 101 waits until acknowledgment information is received until a predetermined time elapses after transmitting the request information (NO in step S304 and NO in step S306).

  On the other hand, when the count value Cnt is equal to or greater than the lower limit value Min (NO in step S310), the traffic flow control device 101 recognizes that the number of terminal devices 202 that have transmitted the acknowledgment information satisfies the target Tgt. The information transmission process ends.

  FIG. 13 is a flowchart that defines an operation procedure when the traffic flow control device according to the first embodiment of the present invention performs a process according to the content of the response information.

  Referring to FIG. 13, first, traffic flow control device 101 receives acknowledgment information and terminal ID from terminal device 202, or receives negative acknowledgment information or neutral response information and terminal ID from terminal device 202. (NO in step S402 and NO in step S418).

  Next, when the traffic flow control device 101 receives the acknowledgment information and the terminal ID from the terminal device 202 (YES in step S402), the traffic flow control device 101 corresponds to the terminal ID in the suppression time zone CP or the time zone based on the suppression time zone CP. The result of the driver to be executed is obtained (step S404).

  Next, the traffic flow control device 101 checks whether or not the acquired result and the content of the acknowledgment information are consistent (step S406).

  Next, the traffic flow control device 101 creates performance information indicating the confirmation result, and accumulates the created performance information, positive response information, and time zone information in the received response information database 127 in association with the terminal ID and the vehicle ID. (Step S408).

  Next, the traffic flow control device 101 calculates an incentive according to the content of the acknowledgment information (step S410).

  Next, when the record information indicates that there is consistency (YES in step S412), the traffic flow control device 101 gives the calculated incentive to the driver (step S414).

  On the other hand, when the record information indicates that there is no consistency (NO in step S412), the traffic flow control device 101 does not give the calculated incentive to the driver (step S416).

  Next, after determining whether or not to give the calculated incentive to the driver (step S414 or step S416), the traffic flow control device 101 receives the acknowledgment information and the terminal ID from the terminal device 202, or denies it. The process waits until response information or neutral response information and the terminal ID are received from the terminal device 202 (NO in step S402 and NO in step S418).

  Further, when the traffic flow control device 101 receives the negative response information or the neutral response information and the terminal ID from the terminal device 202 (NO in step S402 and YES in step S418), the received negative response information or neutral response information, and the time The band information is stored in the received response information database 127 in association with the terminal ID and the vehicle ID (step S420).

  Next, the traffic flow control device 101 calculates zero as a price (step S422).

  Next, the traffic flow control device 101 waits until the acknowledgment information and the terminal ID are received from the terminal device 202 or the negative acknowledgment information or the neutral response information and the terminal ID are received from the terminal device 202 (step S402). NO at step S418 and NO at step S418).

  Note that the order of steps S404, S406, and S408 and S410 is not limited to the above, and the order may be changed.

  The order of steps S420 and S422 is not limited to the above, and the order may be changed.

  In the traffic flow control device according to the first embodiment of the present invention, the traffic regulation information processing unit 22 is configured to set the suppression time zone CP in which the traffic suppression is scheduled. It does not do. The traffic regulation information processing unit 22 may have any configuration as a time zone acquisition unit, for example, to acquire the suppression time zone CP set in a device other than the traffic flow control device 101.

  In addition, in the traffic flow control device according to the first embodiment of the present invention, the traffic regulation information processing unit 22 is configured to determine the target area A1, but is not limited to this. The traffic regulation information processing unit 22 may be configured to acquire the target area A1 determined by an apparatus other than the traffic flow control apparatus 101, for example, as the area acquisition unit.

  In addition, the traffic flow control device according to the first embodiment of the present invention is configured to include the function of the response acquisition unit, and the calculation unit 26 and the setting unit 23, but is not limited thereto. A device other than the traffic flow control device 101 may be configured to include the function of the response acquisition unit and the calculation unit 26 and the setting unit 23.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the target area A1 is an area including the suppression area CA, but is not limited to this. The target area A1 may be the suppression area CA itself, or may be an area that does not include the suppression area CA.

  In the traffic flow control device according to the first embodiment of the present invention, the target area A1 is a road section connected to the suppression area CA and an area including the suppression area CA, but is not limited thereto. Not something. The target area A1 may be an area that includes a road section that is not connected to the suppression area CA, and may be an area that does not include the suppression area CA.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the request information indicates that public transportation is used and that the vehicle passes through the target area A1 in a time zone different from the suppression time zone CP. Although shown, it is not limited to this. The request information may indicate either use of public transportation or passing through the target area A1 in a time zone different from the suppression time zone CP.

  In the traffic flow control device according to the first embodiment of the present invention, the extraction unit 24 travels in the target area A1 during the suppression time zone CP based on the trajectory information indicating the past travel route of the vehicle 1. Although the target vehicle is predicted, the present invention is not limited to this. The extraction unit 24 may predict a target vehicle that travels in the target area A1 during the suppression time zone CP based on the trajectory information FT indicating a future travel route of the vehicle 1. More specifically, the future travel route of the vehicle 1 is obtained by, for example, statistically processing the past or current travel route of the vehicle 1. The extraction unit 24 acquires, for example, the travel route of the vehicle 1 in the suppression time zone CP from the trajectory information FT, and predicts a target vehicle that travels the target area A1 in the suppression time zone CP based on the acquired travel route. Is also good.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the extraction unit 24 selects the target area A1 from the vehicles 1 traveling from the upstream area UA to the downstream area LA based on the trajectory information. Although the configuration is such that the target vehicle traveling in the suppression time zone CP is extracted, the present invention is not limited to this. The extraction unit 24 may be configured to extract a target vehicle that travels in the target area A1 in the suppression time zone CP based on the trajectory information regardless of the traveling direction of the vehicle 1.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the setting unit 23 is configured to set the target Tgt related to the reduced number of vehicles traveling in the target area A1 in the suppression time zone CP. However, the present invention is not limited to this. The setting unit 23 may be configured to set a target related to the number of vehicles that travel in the target area A1 during the suppression time zone CP, or to set the target number of vehicles that travel in the target area A1 during the suppression time zone CP. A configuration in which targets relating to both the number of units to be reduced may be set.

  Further, in the first embodiment of the present invention, the suppression area CA in which traffic suppression is to be performed is the restricted lane section indicated by the traffic regulation information, but is not limited to this. The suppression area CA where the traffic suppression is scheduled to be performed may be a road section or an area that is specified in advance and does not want to cause traffic congestion.

  By the way, the traffic congestion mitigation device described in Patent Literature 1 is configured to create congestion mitigation information from a measurement result of a vehicle traveling on an upstream side by a sensor and transmit the created congestion mitigation information to a vehicle on a downstream side. For example, when traffic regulation is performed on the downstream side, it is difficult to transmit information for alleviating congestion due to the traffic regulation to vehicles on the upstream side.

  On the other hand, in the traffic flow control device according to the first embodiment of the present invention, the traffic regulation information processing unit 22 sets the target area A1 which is an area based on the suppression area CA where the traffic suppression is to be performed. The area information indicating the time zone information and the time zone information indicating the suppression time zone CP in which the traffic suppression is scheduled are acquired. The extraction unit 24 extracts a target vehicle that is the vehicle 1 predicted to travel in the target area A1 during the suppression time period CP. Then, the communication processing unit 25 notifies the terminal device 202 corresponding to the target vehicle of request information indicating requesting not to travel in the target area A1 during the suppression time zone CP.

  With such a configuration, the driver of the target vehicle can recognize the target area A1 in which the traffic congestion is likely to occur and the suppression time zone CP in which the traffic congestion is likely to occur from the notification content to the terminal device 202. Therefore, traveling in the target area A1 during the suppression time zone CP can be avoided. Thus, the number of vehicles 1 traveling in the target area A1 during the suppression time zone CP can be reduced, so that the possibility of congestion can be reduced. Therefore, traffic congestion in the target area can be reduced.

  In the traffic flow control device according to the first embodiment of the present invention, the target area A1 is an area including a road section connected to the suppression area CA and the suppression area CA.

  With such a configuration, it is possible to prevent the vehicle 1 from traveling in the suppression time zone CP not only in the suppression area CA but also in a road section where traffic congestion is likely to occur due to traffic suppression. Further, since the range of the target area A1 can be specified using the road section connected to the suppression area CA, the driver of the target vehicle can easily recognize the target area A1.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the traffic regulation information processing unit 22 determines the target area A1 and determines the probability that the vehicle 1 traveling on the road section travels in the suppression area CA. Based on the plurality of road sections, a road section to be included in the target area A1 is selected.

  With such a configuration, it is possible to accurately select a road section in which traffic congestion is likely to occur due to traffic suppression, so that the range of the target area A1 can be appropriately determined.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the extraction unit 24 specifies the upstream area UA and the downstream area LA based on the suppression area CA, and specifies the downstream area from the specified upstream area UA. From the vehicles 1 traveling to LA, target vehicles predicted to travel in the target area A1 during the suppression time zone CP are extracted.

  As described above, with the configuration in which the target vehicle is extracted from the vehicles 1 traveling in the traffic suppression direction, a more appropriate vehicle 1 can be extracted as the target vehicle.

  In the traffic flow control device according to the first embodiment of the present invention, the extraction unit 24 sets the target area A1 to the suppression time zone CP based on the trajectory information indicating the past or future travel route of the vehicle 1. The running target vehicle is extracted.

  With such a configuration, for example, a past or future traveling pattern of each vehicle 1 can be obtained from the trajectory information, so that the target vehicle can be accurately extracted.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the request information indicates that the public transportation is used and that the request information passes through the target area A1 in a time zone different from the suppression time zone CP. Indicates at least one of them.

  As described above, the configuration that presents an effective method for reducing the number of vehicles 1 traveling in the target area A1 during the suppression time period CP can further reduce the possibility of occurrence of congestion in the target area A1.

  In the traffic flow control device according to the first embodiment of the present invention, the communication processing unit 25 acquires response information from the terminal device 202 to the request information. Then, the calculation unit 26 calculates a price based on the content of the response information acquired by the communication processing unit 25.

  With such a configuration, it is possible to calculate an appropriate price according to the content of the response information, and thus it is possible to enhance the driver's satisfaction. This makes it easier for the driver to cooperate, thereby reducing the possibility of congestion in the target area A1.

  Further, in the traffic flow control device according to the first embodiment of the present invention, the setting unit 23 sets the number of the vehicles 1 traveling when traffic suppression is not performed in the suppression area CA, and the planned traffic suppression. Based on the content, a target Tgt is set for at least one of the number of vehicles 1 and the number of vehicles 1 that are traveling in the target area A1 during the suppression period CP. The communication processing unit 25 acquires response information from the terminal device 202 to the request information. Then, the communication processing unit 25 determines whether to notify the other terminal device 202 of the request information based on the target Tgt set by the setting unit 23 and the response information acquired by the communication processing unit 25. .

  With such a configuration, it is possible to set an appropriate target Tgt for preventing the occurrence of traffic congestion in the target area A1, and to obtain the achievement status of the number of target vehicles participating in traffic suppression with respect to the set target Tgt. can do. Then, for example, by notifying the request information to the other terminal devices 202 when the target Tgt has not been reached, the possibility of achieving the target can be increased, so that the possibility of occurrence of traffic congestion in the target area A1 is further reduced. Can be lowered.

  Further, in the terminal device according to the first embodiment of the present invention, the reception unit 41 sets the target area A1, which is an area based on the suppression area CA where the traffic suppression is scheduled to be performed, in the suppression time in which the traffic suppression is scheduled. Request information indicating that the belt CP is requested not to travel by vehicle is received. Then, the transmitting unit 45 transmits response information to the request information.

  With such a configuration, the user of the terminal device 202 recognizes the target area A1 in which the traffic congestion is likely to occur and the suppression time zone CP in which the traffic congestion is likely to occur from the notification contents to the terminal device 202. Therefore, traveling in the target area A1 during the suppression time zone CP can be avoided. Thus, the number of vehicles traveling in the target area A1 during the suppression time zone CP can be reduced, so that the possibility of occurrence of congestion can be reduced. Therefore, traffic congestion in the target area can be reduced.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions have the same reference characters allotted, and description thereof will not be repeated.

<Second embodiment>
The present embodiment relates to a traffic flow control system that takes into account the driver's contribution to traffic suppression in extracting a target vehicle as compared with the traffic flow control system according to the first embodiment. The contents other than those described below are the same as those of the traffic flow control system according to the first embodiment.

[Task]
For example, when the number of vehicles participating in traffic suppression is small, it may be difficult to reduce traffic congestion in the target area A1. On the other hand, when the number of vehicles participating in traffic suppression is large, congestion may occur in an area located outside the target area A1 even if the congestion in the target area A1 is reduced.

  As described above, since it is important to accurately estimate the number of participating vehicles in traffic suppression, there is a need for a technology capable of more accurately estimating the number of participating vehicles.

  Therefore, the traffic flow control system according to the second embodiment of the present invention solves such a problem by the following configuration and operation.

[Configuration of traffic flow control device]
FIG. 14 is a diagram showing a configuration of the traffic flow control device in the traffic flow control system according to the second embodiment of the present invention.

  Referring to FIG. 14, the traffic flow control device 102 in the traffic flow control system 301 according to the second embodiment of the present invention includes a traffic regulation information acquisition unit 21 and a traffic regulation information processing unit (a time zone acquisition unit, It includes an area acquisition unit and a determination unit 22, a setting unit 23, a calculation unit 26, a performance processing unit 28, an extraction unit 34, and a communication processing unit (notification unit and response acquisition unit) 35.

  The operation of the traffic regulation information acquisition unit 21, the traffic regulation information processing unit 22, the setting unit 23, the calculation unit 26, and the performance processing unit 28 in the traffic flow control device 102 is the same as that of the traffic flow control device 101 shown in FIG. The same as the section 21, the traffic regulation information processing section 22, the setting section 23, the calculating section 26, and the result processing section 28, respectively.

  For example, the extraction unit 34 determines the target vehicle based on the response content that is the content of past response information from the terminal device 202 to the request information, the target vehicle's action performance with respect to the request information, and the target Tgt set by the setting unit 23. Is extracted.

  More specifically, the extraction unit 34 calculates an evaluation value based on at least one of the response content and the action result, for example.

  FIG. 15 is a diagram illustrating an example of the reactivity list created by the extraction unit in the traffic flow control device according to the second embodiment of the present invention.

  Referring to FIG. 15, extraction unit 34 creates, for example, a list indicating the correspondence between terminal device 202 and the evaluation value for each time zone. More specifically, the extraction unit 34 creates a reactivity list Rlst1 indicating the correspondence between the terminal ID of the terminal device 202 and the evaluation value for each time zone, for example, the reactivity. The extraction unit 34 creates the reactivity list Rlst1 for a predetermined time, for example, every day.

  FIG. 16 is a flowchart that defines an operation procedure when the extraction unit in the traffic flow control device according to the second embodiment of the present invention performs a process of creating a reactivity list.

  Referring to FIGS. 15 and 16, extraction unit 34 determines the response of 24 types of time zones of three days from 0:00 to 24:00 for each day type and for terminal devices 202 with terminal IDs 1 to 500. Assume that you want the degree.

  First, the extraction unit 34 initializes an index “kid” indicating a terminal ID to 1 (Step S502).

  Next, the extraction unit 34 initializes an index kdt for identifying 24 types of time zones to 1 (step S504).

  Next, the extraction unit 34 sets a day type and a time zone corresponding to the index kdt. For example, when the value of the index kdt is 1, the day type and the time zone are “weekdays” and “00:00 to 3:00”, respectively (step S506).

  Next, the extraction unit 34 calculates the number Nreq of transmitted request information that satisfies the following condition Cd1 based on the transmitted request information in the transmitted request information database 126 (Step S508).

  Here, the condition Cd1 is that the transmitted request information corresponds to the terminal ID having the same value as the index kid, and is a suppression time zone CP in the same day type as the set day type, and is included in the set time zone. This is whether or not time zone information indicating the suppression time zone CP is included.

  Next, when the number Nreq is greater than zero (YES in step S510), the extraction unit 34 acquires response information that satisfies the following condition Cd2 based on the response information in the received response information database 127, and acquires the acquired response. The number Nres of information is calculated (step S512).

  Here, the condition Cd2 is that the response information corresponds to the terminal ID having the same value as the index “kid”, and is the suppression time zone CP in the same day type as the set day type, and the suppression time included in the set time zone. Whether or not time zone information indicating the zone CP is included.

  Next, using the calculated number Nres, the extraction unit 34 performs a reactivity calculation process for calculating a reactivity Re, which will be described later, and writes the calculated reactivity Re in a corresponding column of the reactivity list Rlst1 ( Step S514).

  On the other hand, when the number Nreq is zero (NO in step S510), the extraction unit 34 does not assign the reactivity and writes “NA” in the corresponding column of the reactivity list Rlst1 (step S516).

  Next, when performing the reactivity calculation processing (step S514) or writing “NA” in the corresponding column of the reactivity list Rlst1 (step S516), the extraction unit 34 increments the index kdt (step S518). .

  Next, when the index kdt is equal to or smaller than 24 (NO in step S520), the extraction unit 34 sets a day type and a time zone corresponding to the index kdt. For example, when the value of the index kdt is 2, the day type and time zone are “weekdays” and “3:00 to 6:00”, respectively (step S506).

  On the other hand, when the index kdt is larger than 24 (YES in step S520), the extraction unit 34 increments the index kit (step S522).

  Next, when the index kid is equal to or less than the maximum value Maxid of the number of terminal IDs, that is, 500 (NO in step S524), the extraction unit 34 initializes the index kdt to 1 again (step S504).

  On the other hand, when the index “kid” is larger than the maximum value “Maxid” (YES in step S524), the extraction unit 34 ends the process of creating the reactivity list Rlst1. At this timing, the reactivity list Rlst1 shown in FIG. 15 is completed.

  FIG. 17 is a flowchart that defines an operation procedure when the extraction unit in the traffic flow control device according to the second embodiment of the present invention performs the reactivity calculation process.

  Referring to FIG. 17, first, extraction unit 34 initializes index kr for identifying Nres pieces of response information satisfying condition Cd2 to 1 (step S602).

  Next, the extraction unit 34 sets zero as an initial value of the reactivity Re (Step S604).

  Next, when the kr-th response information is not the positive response information (NO in step S606), the extraction unit 34 subtracts the depolarization level a1 from the reactivity Re (step S608).

  On the other hand, when the kr-th response information is the positive response information and the result information corresponding to the positive response information indicates that there is no consistency (YES in step S606 and YES in step S610), the extraction unit 34 performs the reaction. The depolarization level a2 is subtracted from the degree Re (step S612).

  In addition, the extraction unit 34 determines that the kr-th response information is positive response information, that the result information corresponding to the positive response information indicates consistency, and that the positive response information is positive response information PR2 ( (YES in step S606, NO in step S610 and YES in step S614), and adds positive level a4 to reactivity Re (step S618).

  On the other hand, the extraction unit 34 determines that the kr-th response information is positive response information, that the result information corresponding to the positive response information indicates consistency, and that the positive response information is not positive response information PR2 (step (YES in S606, NO in step S610 and NO in step S614), and adds positive level a3 to reactivity Re (step S616).

  Next, the extracting unit 34 subtracts the depolarization level a1 from the reactivity Re (Step S608), subtracts the depolarization level a2 from the reactivity Re (Step S612), or adds the positive level a4 to the reactivity Re (Step S612). If the positive level a3 is added to the reactivity Re (S618) or the reactivity Re (Step S616), the index kr is incremented (Step S620).

  Next, when the index kr is equal to or smaller than Nres (NO in step S622), the extraction unit 34 determines whether or not the kr-th response information is positive response information (step S606).

  On the other hand, when the index kr is greater than Nres (YES in step S622), the extraction unit 34 determines whether the reactivity Re is greater than 1 (step S624).

  When determining that the reactivity Re is greater than 1 (YES in step S624), the extraction unit 34 sets the reactivity Re to 1.0 (step S626).

  On the other hand, when determining that the reactivity Re is 1 or less (NO in step S624), the extracting unit 34 determines whether the reactivity Re is smaller than zero (step S628).

  When determining that the reactivity Re is smaller than zero (YES in step S628), the extraction unit 34 sets the reactivity Re to 0.0 (step S630).

  On the other hand, when determining that the reactivity Re is equal to or greater than zero (NO in step S628), the extraction unit 34 maintains the reactivity Re.

  Referring again to FIG. 14, for example, the extraction unit 34 acquires the positive response information in comparison with the evaluation value obtained when the negative response information is acquired, and the corresponding target vehicle sets the target area A1 in the suppression time zone. The evaluation value when traveling to the CP is calculated so as to be disadvantageous for extracting the target vehicle.

  Specifically, in this example, as described later, the target vehicle having a large evaluation value is preferentially extracted, so that the extracting unit 34 compares the positive response information with the negative response information, for example, when acquiring the negative response information. The evaluation value obtained when the acquired target vehicle travels in the target area A1 during the suppression time zone CP is calculated to be low.

  More specifically, the extraction unit 34 sets the depolarization levels a1 and a2 used in the reactivity calculation processing so that the relationship of 0 <= a1 <a2 <1 is satisfied.

  When the negative response information is to be processed in the reactivity calculation processing, the extraction unit 34 subtracts the depolarization level a1 from the current reactivity Re.

  On the other hand, when the acknowledgment information is to be processed in the reactivity calculation processing, the extraction unit 34 acquires the performance information (see FIG. 2) corresponding to the acknowledgment processing from the received response information database 127 and acquires the acquired information. When the performance information indicates no consistency, the depolarization level a2 is subtracted from the current reactivity Re.

  In addition, the extraction unit 34 compares the target vehicle with the target area A1 by using public transportation compared with the evaluation value when the target vehicle does not travel in the target area A1 during the suppression time zone CP by using the alternative route. Is calculated so as to be advantageous for extracting the target vehicle when the vehicle is not driven during the suppression time zone CP.

  More specifically, as described above, in this example, a target vehicle having a large evaluation value is preferentially extracted. Therefore, the extraction unit 34 suppresses the target area A1 by using, for example, an alternative route. As compared with the case where the vehicle does not travel in the time zone CP, the evaluation value when the target vehicle does not travel in the target area A1 in the suppression time zone CP by using public transportation is calculated to be higher.

  More specifically, the extraction unit 34 sets the positive levels a3 and a4 used in the reactivity calculation processing so that the relationship of 0 <= a3 <a4 <1 is satisfied.

  When the affirmative response information PR2 is to be processed in the reactivity calculation process, the extraction unit 34 adds the positive level a4 to the current reactivity Re.

  On the other hand, when the acknowledgment information PR1 or PR3 is to be processed in the reactivity calculation process, the extraction unit 34 adds the positive level a3 to the current reactivity Re.

  Further, as shown in FIG. 5, the extraction unit 34 determines that the vehicle IDs passing through the trajectories Tr1, Tr2, Tr3, Tr4, and Tr5 are respectively 1 to 100, 101 to 200, 201 to 300, 301 to 400, and 401 to 500 vehicles 1 are specified as approach vehicles.

  Then, the extraction unit 34 extracts, as the target vehicle, the vehicle 1 that has traveled in the target area A1 in the same day type and the same time period as the suppression time zone CP among the specified approach vehicles.

  In this example, as illustrated in FIG. 5, the extraction unit 34 specifies the vehicles 1 having vehicle IDs of 1 to 100, 101 to 200, and 201 to 300 that have passed the trajectories Tr1, Tr2, and Tr3 as target vehicles. .

  Further, the extraction unit 34 acquires the target Tgt set by the setting unit 23, for example, 50 to 70 units from the setting unit 23.

  The extraction unit 34 extracts a target vehicle based on the calculated evaluation value, for example. Specifically, the extraction unit 34 extracts a target vehicle based on the reactivity list Rlst1.

  More specifically, for example, when the day type and the time zone of the suppression time zone CP are “weekdays” and “10:00 to 11:00”, the extraction unit 34 includes 1 to 300 in the reactivity list Rlst1. And the respective reactivity in the region R1 corresponding to “weekdays” and “10:00 to 11:00”.

  The extracting unit 34 preferentially extracts, for example, a target vehicle having a large evaluation value. Specifically, the extraction unit 34 sequentially obtains the reactivity from the reactivity in the region R1 in descending order. Then, when the total of the obtained degrees of reactivity exceeds, for example, 60 which is the median of the target Tgt, the extraction unit 34 specifies the terminal ID corresponding to each of the obtained degrees of reactivity as the transmission destination of the request information.

  Note that the extraction unit 34 may preferentially extract a target vehicle having a small evaluation value. In this case, as compared with the case where the negative response information is obtained, the extraction unit 34 obtains the positive response information and calculates a higher evaluation value when the corresponding target vehicle travels in the target area A1 during the suppression time zone CP. I do. In addition, the extraction unit 34 uses the public transportation to reduce the target area A1 in the target area A1 in comparison with the case where the target vehicle does not travel in the target area A1 during the restriction time zone CP by using the alternative route. The evaluation value when the vehicle does not travel in the zone CP is calculated to be low.

  In addition, the extraction unit 34 assigns, for example, about several percent of the terminal IDs specified as the transmission destinations of the request information to the terminal IDs corresponding to “NA” and the small reactivity so that the specified terminal IDs are not biased. At least one of the corresponding terminal IDs may be randomly selected and replaced with the selected terminal ID.

  The extraction unit 34 may screen each terminal ID in the reactivity list Rlst1.

  More specifically, for example, based on the transmitted request information in the transmitted request information database 126, the extraction unit 34 determines, among the terminal IDs in the reactivity list Rlst1, the destination of the request information as a destination of the request information for a predetermined number of times or more. A terminal ID is acquired, and a terminal ID to which the request information is transmitted is specified from the acquired terminal IDs.

  The extraction unit 34 outputs the vehicle ID corresponding to the specified terminal ID, the trajectory corresponding to the vehicle ID, the time zone information, and the area information to the communication processing unit 35.

  When receiving the vehicle ID of the target vehicle, the trajectory corresponding to the vehicle ID, and the time zone information and the area information from the extraction unit 34, the communication processing unit 35 performs the suppression time zone based on the received time zone information and the area information. The CP, the restriction link L1 in which the suppression area CA is located, the restriction direction CD, and the range of the target area A1 are recognized.

  Further, when receiving the target information from the setting unit 23, the communication processing unit 35 recognizes from the received target information that the lower limit and the median of the target Tgt are 50 and 60, respectively.

  Further, the communication processing unit 35 acquires the driver information from the driver information database 124 and, based on the acquired driver information and the vehicle ID received from the extraction unit 34, determines the terminal ID of the terminal device 202 corresponding to the vehicle ID. get.

  In addition, the communication processing unit 35 creates the alternative link use request information, the public transport use request information, and the time difference travel request information, and creates the alternative link use request information, public The traffic use request information, the time difference travel request information, the time zone information, and the area information are transmitted to the terminal device 202 with the obtained terminal ID as a destination. At this time, the communication processing unit 35 transmits the substitute link use request information and the public transport use request information of the vehicle ID corresponding to the acquired terminal ID.

  When receiving the response information to the request information and the terminal ID from the terminal device 202, the communication processing unit 35 acquires the vehicle ID corresponding to the terminal ID based on the received terminal ID and the held ID information.

  The communication processing unit 35 confirms the content of each response information received before the predetermined time has elapsed since the transmission of the request information, and thereby determines the number of acknowledgment information PR1, PR2, PR3 included in each response information. Count.

  If the counted number is less than the lower limit of the target Tgt of 50, the communication processing unit 35 determines to transmit the request information to another terminal device 202.

  More specifically, the communication processing unit 35 notifies the extraction unit 34 of an additional value obtained by subtracting the number from 60, which is the median of the target Tgt.

  Upon receiving the notification of the additional value from the communication processing unit 35, the extraction unit 34 sequentially obtains the reactivity in the descending order of the reactivity not obtained in the region R1. Then, when the sum of the obtained degrees of reactivity exceeds, for example, the additional value, the extraction unit 34 specifies the terminal ID corresponding to each obtained degree of reactivity as a transmission destination of the request information.

  The extraction unit 34 outputs the vehicle ID corresponding to the specified terminal ID, the trajectory corresponding to the vehicle ID, the time zone information, and the area information to the communication processing unit 35.

Create for each type.

  Specifically, the extraction unit 34 creates a reactivity list Tlst2 indicating the correspondence between the terminal ID of the terminal device 202 and the reactivity for each price, that is, for each incentive level.
