  In order to solve the above problems, the road traffic optimization system of the present invention has the following features.

  A road traffic optimization system according to the present invention includes a first terminal mounted on a vehicle and operated by a user, a plurality of second terminals mounted on the vehicle traveling on the road and transmitting location information at predetermined intervals, and a network And a server connected to the first terminal and the plurality of second terminals via the first terminal, wherein the first terminal specifies current position information indicating a current position and the user Route information transmitting means for transmitting to the server route information including destination information indicating the destination, and a toll value indicating a toll for a section between the current position and the destination is received from the server. The toll fee value receiving means, a plurality of types of routes from the current position to the destination, and the toll fee value receiving means received in the section included in the plurality of types of routes. Display control means for controlling the display of a route selection screen for prompting selection of one of the plurality of types of routes on the display means, and the route selection operation by the user And an input means for transmitting the selected route information indicating the route selected in the selection operation received by the input means to the server, the server receiving from the first terminal Received from the plurality of second terminals mounted on the vehicle passing through the section between the current position and the destination indicated by the current position information and the destination information included in the route information. A traffic jam degree calculating means for calculating a traffic jam degree indicating a traffic jam status of the road in the section based on the position information for each predetermined interval; A toll value calculating means for calculating the toll value for the section according to the congestion degree calculated by the calculating means, and a toll for transmitting the toll value calculated by the toll value calculating means to the first terminal. Based on the charge value transmitting means, the selected route information received from the first terminal, the selected section specifying means for specifying the section included in the route indicated by the selected route information, and the selected section specifying means specified Charge amount calculating means for setting the toll value calculated by the toll fee value calculating means in the section to a charged amount value indicating a charged amount to be charged to the user.

  According to the above configuration, the first terminal mounted on the vehicle and operated by the user, the plurality of second terminals mounted on the vehicle traveling on the road and transmitting position information at predetermined intervals, and the first terminal via the network And a server connected to the terminal and the plurality of second terminals. The first terminal includes route information transmitting means, toll charge value receiving means, display control means, input means, and selected route transmitting means. The route information transmitting means transmits route information including current position information indicating the current position and destination information indicating the destination designated by the user to the server. The toll fee value receiving means receives a toll fee value indicating a toll for the section between the current position and the destination from the server. The display control means indicates a plurality of types of routes from the current position to the destination and a toll based on a toll value received by the toll value receiving means in a section included in the plurality of types of routes. Control is performed to display a route selection screen for prompting selection of any of the routes on the display means. The input means accepts a route selection operation by the user. The selected route transmission unit transmits selected route information indicating the route selected in the selection operation received by the input unit to the server. The server includes a traffic congestion degree calculating means, a toll fee value calculating means, a toll fee value transmitting means, a selected section specifying means, and a billing amount calculating means. The congestion degree calculating means includes a plurality of second terminals mounted on a vehicle passing through a section between the current position and the destination indicated by the current position information and the destination information included in the route information received from the first terminal. Based on the positional information received at predetermined intervals, the degree of congestion indicating the traffic congestion on the road in the section is calculated. The toll fee value calculating means calculates a toll value for the section according to the traffic jam degree calculated by the traffic jam degree calculating means. The toll fee value transmitting means transmits the toll fee value calculated by the toll fee value calculating means to the first terminal. The selected section specifying means specifies a section included in the route indicated by the selected route information based on the selected route information received from the first terminal. The billing amount calculation means sets the toll value calculated by the toll fee value calculation means in the section specified by the selection section specifying means to a billing amount value indicating the billing amount charged to the user.

  In this way, the server calculates a toll according to the degree of traffic congestion in the section between the current location of the first terminal and the destination designated by the user. This toll is displayed on the display means of the first terminal as a toll in a section included in a plurality of types of routes from the current position to the destination. Then, the user can be charged for the toll for the route selected from a plurality of types of routes. Thereby, the user can confirm the toll for each route displayed on the display means in advance before actually departing, and can select the route to the destination by an economical approach. Here, the user generally selects a route with a lower toll than a route with a higher toll. For this reason, for example, the higher the degree of congestion in a certain section (the more congested it is), the higher the toll is set, the section where the user is congested is prevented from being selected and used. Can alleviate traffic jams. Therefore, it is possible to provide a road traffic optimization system that can alleviate traffic congestion in consideration of a point that the user selects a road section to be used by an economical approach.

  In the road traffic optimization system according to the present invention, the toll value calculation means indicates a variable toll that varies according to the degree of congestion in a reference value indicating a reference toll set in advance for each section. The toll value is calculated by adding a fluctuation value.

  By doing in this way, in addition to the variable toll that fluctuates according to the degree of congestion, a toll value obtained by adding a standard toll set in advance for each section can be calculated. Here, for example, a standard toll for a section that passes through an area where vehicle traffic is not desirable, such as a residential area or an area where a landscape is desired to be protected, is set higher than a section that passes through another area. In addition, a standard toll for a section where traffic congestion is likely to occur, for example, a section convenient for accessing a concert venue or a stadium, a section with beautiful illumination, and the like is set higher than a section passing through another area. In addition, standard tolls for sections that you want to maintain vacant, such as sections that you want to prevent traffic jams in preparation for emergency vehicle travel, sections that you want to set on tourist roads that travelers can enjoy comfortably, etc. Set higher than the section that passes through other areas. This prevents the user from selecting and using sections that pass through areas where vehicle traffic is not desirable, sections where traffic congestion is likely to occur, or sections where it is desired to maintain vacancy, and traffic congestion occurs in those sections. Can be prevented in advance.

  The road traffic optimization system of the present invention further includes a reference toll storage unit that stores the reference value for each of a plurality of periods in association with the section, and the toll fee value calculating unit includes the reference Referring to the toll storage means, the toll value is calculated by adding the fluctuation value to the reference value of the period including the current time.

  By doing in this way, in addition to the variable toll that fluctuates according to the degree of congestion, a toll value that is obtained by adding a standard toll set in advance for each period can be calculated. Here, for example, in a section along the coast where a gorgeous summer scenery can be seen, congestion occurs in the summer. In addition, the section along the mountain where you can enjoy the snow scenery from autumn to autumn leaves a traffic jam from autumn to winter. Thus, there is a section where traffic jam occurs depending on the period. Therefore, for example, in a certain section, a reference toll for a period in which traffic congestion is likely to occur is set higher than in other periods. Thereby, in a certain section, it is possible to prevent the section from being selected and used by a user during a period in which the congestion is likely to occur, and to prevent the congestion from occurring in the section in advance.

  Further, in the road traffic optimization system according to the present invention, the congestion degree calculating means includes the section specified by the selected section specifying means and the position information received at the predetermined intervals from the plurality of second terminals. And calculating the degree of congestion in the section.

  Here, the section specified by the selected section specifying means is a section selected by the user and is a section scheduled to be used in the future. For example, at a certain point in time, the number of sections specified by the selected section specifying unit is more likely to be congested than other sections. Therefore, the section specified by the selected section specifying means is information suggesting the possibility of future traffic congestion. Therefore, according to the present invention, the degree of congestion can be calculated based on the position information received from the second terminal at predetermined intervals, that is, real-time information and information that suggests the possibility of future congestion. As a result, a toll according to the degree of congestion including future prediction in a certain section is shown, and a section that is highly likely to be congested by the user is selected and used, and the congestion in the section can be alleviated.

  Further, the present invention can be regarded as a road traffic optimization method as follows. A first terminal mounted on a vehicle and operated by a user, a plurality of second terminals mounted on the vehicle passing on a road and transmitting position information at predetermined intervals, the first terminal and the plurality of terminals via a network And a server connected to the second terminal of the road traffic optimizing method executed by the road traffic optimizing system, the current location information indicating the current location in the first terminal and designated by the user A route information transmission stage for transmitting route information including destination information indicating a destination to the server, and a passage for receiving a toll value indicating a toll for a section between the current position and the destination from the server.

In addition, when the route information transmission unit 101 receives the condition information, the display control unit 103 performs traffic in a plurality of types of routes that satisfy the conditions indicated by the received condition information and sections included in the plurality of types of routes. Control may be performed to display a route selection screen on the display unit 104 that indicates a toll based on the toll value received by the toll value receiving unit 102 and prompts the user to select one of the plurality of types of routes.

  FIG. 3 is a diagram showing an example of a route selection screen displayed on the display unit 104 according to the embodiment of the present invention. In the example of FIG. 3, the route selection screen includes a plurality of types of routes (route A, route B, and route C) from the current position (“S”) to the destination (“R”), and a plurality of types of routes. Tolls in the included sections (sections A1, A2 and A3, sections B1, B2, B3 and B4, sections C1 and C2) are shown, and multiple types of routes (route A, route B and route C) A character image that prompts the user to select one of the above is displayed.

  Returning to FIG. 2, the display means 104 displays a route selection screen. The input unit 105 receives a route selection operation by the user (touch operation of any one of the button A, the button B, and the button C in the example of FIG. 3). In the present embodiment, the display unit 104 and the input unit 105 are configured by a touch panel. However, the present invention is not limited thereto, and the display unit 104 may be configured by a display and the input unit 105 may be configured by an input key.

  The selected route transmission unit 106 transmits the selected route information indicating the route selected in the selection operation received by the input unit 105 to the server 20.

  The position information transmitting unit 111 of the second terminal 11 acquires position information at a predetermined interval (for example, 0.1 second interval), and transmits the acquired position information to the server 20. Specifically, the position information transmission unit 111 receives a GPS signal from a GPS satellite, calculates position information based on the received GPS signal, and transmits the position information to the server 20. Specifically, the position information transmission unit 111 of the second terminal 11 and the route information transmission unit 101 of the first terminal 10 described above complement the received GPS signal with (the vehicle speed pulse (= total travel distance) of the vehicle, The information is further corrected with map information (map matching) to calculate the current position information, and the position information transmission unit 111 and the route information transmission unit 101 can calculate based on the GPS signal if the current position information can be calculated. For example, a plurality of wireless LAN (Local Area Network) access points installed around the first terminal 10 or the second terminal 11 are detected, and radio wave information is received from the wireless LAN access point. Current position information may be calculated based on the radio wave information.

  The server 20 includes a congestion degree calculating unit 201, a toll fee value calculating unit 202, a toll fee value transmitting unit 203, a selection section specifying unit 204, a billed amount calculating unit 205, a toll fee requesting unit 206, a variable toll A fee database (hereinafter also referred to as a variable toll DB) 210 and a reference toll database (hereinafter also referred to as a reference toll DB) 220 serving as a reference toll storage means.

  The congestion degree calculation means 201 includes a plurality of second vehicles placed on a vehicle passing through a section between the current position and the destination indicated by the current position information and the destination information included in the route information received from the first terminal 10. Based on the positional information received from the two terminals 11 at predetermined intervals, the degree of traffic congestion on the road in the section is calculated. Specifically, the congestion degree calculation unit 201 calculates the travel distance of the second terminal 11 at a predetermined time based on the position information received from the second terminal 11 at predetermined intervals, and divides the travel distance by the predetermined time. Thus, the moving speed of each second terminal 11 is calculated. Then, the congestion degree calculation unit 201 refers to the variable toll fee DB 210 and determines the congestion degree according to the calculated moving speed.

  FIG. 4 is a diagram illustrating the variable toll DB 210 according to the embodiment of the present invention. In the variable toll DB 210, a moving speed and a fluctuation value are associated with a plurality of levels of congestion (for example, five levels 1 to 5). For example, if the calculated travel speed is 20 km / h or less, the traffic congestion degree calculation unit 201 refers to the variable toll DB 210 and determines the traffic congestion degree to “5”. On the other hand, if the calculated travel speed is 61 km / h or more, the traffic congestion degree calculation means 201 refers to the variable toll DB 210 and determines the traffic congestion degree to “1”. That is, in the present embodiment, the degree of traffic congestion is determined to be a high value by estimating that the traffic speed is slower as the moving speed is slower.

  Further, the congestion degree calculation unit 201 calculates the congestion degree in the section based on the section specified by the selection section specifying unit 204 described later and the position information received from the plurality of second terminals 11 at predetermined intervals. Specifically, the congestion degree calculating unit 201 upwardly corrects the congestion degree determined with reference to the variable toll DB 210 according to the number of times a selected section specifying unit 204 described later specifies a certain section. In addition, although mentioned later in detail, the frequency | count that the selection area specific | specification means 204 specified a certain area is the number of vehicles which plan to use the said certain area from now on. For example, if the number of times a selected section is specified by the selected section specifying unit 204 is “10”, it is estimated that 10 vehicles will use the certain section in the future. For example, when the number of times a certain section is specified by the selected section specifying means 204 is “10” to “20”, the congestion degree calculating means 201 sets the congestion degree determined by referring to the variable toll DB 210 to “1”. “Upward correction (for example, if the congestion level determined with reference to the variable toll DB 210 is“ 2 ”, the congestion level is set to“ 3 ”). Further, for example, when the number of times a certain section is specified by the selected section specifying means 204 is “21” to “30”, the congestion degree calculating means 201 uses the congestion degree determined with reference to the variable toll DB 210. “2” is corrected upward (for example, if the congestion level determined with reference to the variable toll DB 210 is “2”, the congestion level is set to “4”). That is, the congestion degree calculation means 201 changes the congestion degree of a certain section determined with reference to the variable toll DB 210 to a higher value as the number of times a certain section is identified by the selected section identification means 204 increases. .

  Returning to FIG. 2, the toll value calculation means 202 calculates the toll value for the section according to the congestion degree calculated by the congestion degree calculation means 201. Specifically, the toll fee value calculation means 202 adds a fluctuating value indicating a fluctuating toll depending on the degree of congestion to a reference value indicating a reference toll set in advance for each section, and obtains a toll value. calculate. More specifically, the toll fee value calculation unit 202 refers to the reference toll fee DB 220 and calculates a toll fee value by adding a fluctuation value to the reference value for the period including the current time. Specifically, the toll fee value calculating means 202 calculates the toll fee value by adding the fluctuation value determined with reference to the variable toll fee DB 210 to the reference value determined with reference to the toll fee value calculating means 202. To do.

  The reference toll DB 220 stores a reference value for each of a plurality of periods in association with a section. FIG. 5 is a diagram illustrating the standard toll DB 220 according to the embodiment of the present invention. The standard toll DB 220 includes a plurality of periods (for example, January to March, April for each section (for example, sections A1, A2 and A3, sections B1, B2, B3 and B4, and sections C1 and C2). -June, July-September, and October-December) are associated with each other. As shown in FIG. 5, the reference value is determined for each section in advance, and may vary depending on the period even in the same section. Further, as shown in FIG. 4, the fluctuation value is set to a higher value (higher price) as the congestion degree is higher (lower movement speed).

  Returning to FIG. 2, the toll fee value transmitting unit 203 transmits the toll value calculated by the toll fee value calculating unit 202 to the first terminal 10. The selected section specifying unit 204 specifies a section included in the route indicated by the selected route information based on the selected route information received from the first terminal 10. Further, the selected section specifying unit 204 stores the specified number of times for each section in a storage area on the memory during a predetermined time (for example, one hour). The congestion degree calculation unit 201 changes the congestion degree based on the value stored in the storage area.

  The billing amount calculation unit 205 sets the toll value calculated by the toll fee value calculation unit 202 in the section specified by the selection section specifying unit 204 to a billing amount value indicating the billing amount charged to the user. Note that the server 20 continuously receives current position information from the first terminal 10 of the vehicle traveling on the route, and verifies the route on which the vehicle actually traveled from the continuously received current position information. May be provided. In this case, the bill amount calculation means 205 calculates a difference value that is the difference between the toll value based on the section specified by the selected section specifying means 204 and the toll value based on the section included in the route verified by the verification means. Then, a value obtained by adding or subtracting the difference value to the toll value based on the section specified by the selected section specifying unit 204 may be set as the billing amount value.

  The toll fee billing unit 206 performs a process of billing the user for a toll fee based on the billed amount value set by the billed amount calculation unit 205. For example, the toll fee charging means 206 can charge a toll fee by a known technique such as ETC (Electronic Toll Collection: automatic collection system), a credit card settlement system, a bank automatic withdrawal system, or the like.

  Note that the functional blocks shown in FIG. 2 are merely examples, and one functional unit may be divided or a plurality of functional units may be configured as one functional unit. The server 20 is not limited to one, and a plurality of servers may be used. Each function has a computer (Central Processing Unit) built in the first terminal 10, the second terminal 11, and the server 20 stored in a storage device such as a ROM (Read Only Memory) or a storage unit such as a hard disk. A computer program that is read by the CPU and executed by the CPU reads and writes necessary data such as tables and map data from a database (DB) stored in a storage device or a storage area in a memory. It is realized by controlling related hardware (for example, input / output device, display device, communication interface device).
