The acquisition unit 131 stores the acquired operation information in the operation information recording unit 122. In addition, for example, when the acquisition unit 131 is instructed to start acquisition of operation information from each vehicle 5 by an administrator of the server device 100, the acquisition unit 131 continues to acquire operation information until an instruction to stop acquisition is given, The storage of the acquired operation information in the operation information recording unit 122 is continued.

  The generation unit 132 refers to the vehicle master 121 and the operation information storage unit 122 to generate OD data and route data. Here, a case where the generation unit 132 generates OD data and route data for the vehicle 5 with the vehicle ID “0001” will be described as an example. The generation unit 132 extracts the operation information of the vehicle 5 with the vehicle ID “0001” from the operation information read from the operation information storage unit 122. When the speed of the operation information is 0 km / h, that is, when the time when the vehicle 5 is stopped is, for example, 5 minutes or longer, the generation unit 132 sets the date and time when the vehicle 5 stops as the previous trip end date and time. Next, the generation unit 132 sets the speed of the operation information to be greater than 0 km / h, that is, the date and time when the vehicle 5 starts to move, for example, “2013/09/20 13:00:31” as the next trip start date and time. . Furthermore, the generation unit 132 next sets the time when the speed of the operation information is 0 km / h, for example, 5 minutes or more, and the date and time when the vehicle 5 stops, for example, “2013/09/20 13:37:11” Trip end date and time. In addition, the stop time of the vehicle 5 for determining the switching of a trip can be made into arbitrary time.

The shape of the vehicle 5 can be designated as, for example, a trailer, a dump truck, or a tow truck. For example, the vehicle size can be designated as light, normal, medium, large, or extra large. The average speed of the vehicle 5 can be specified as, for example, 20 km / h, 20 to 25 km / h, 25 to 30 km / h, 30 km / h or more.

  The reception unit 133 may receive a specific point on the road. FIG. 7 is a diagram illustrating another example of the selection screen. As illustrated in FIG. 7, for example, the reception unit 133 generates a selection screen 23 including a map and transmits the selection screen 23 to the terminal device 10. The terminal device 10 displays the received selection screen 23 on a display unit (not shown). For example, when the point 24 is designated by the analyst, the terminal device 10 transmits the selected point 24 as selection information to the server device 100. The reception unit 133 of the server device 100 receives the selection of the spot 24 when receiving the selection information.

Thereby, the map display system 1 can display in an easy-to-see manner which zone each vehicle 5 passing through the designated point 26 has as a departure place or an arrival place. Examples of zones with a large amount of generated concentration include, for example, industrial parks where a plurality of factories are located, and harbors where luggage is accumulated.

  In addition, the display control unit 135 may generate a display screen including a moving route of each vehicle 5 passing through a specific point or range on the road received by the receiving unit 133. FIG. 9 is a diagram illustrating another example of the display screen. As shown in FIG. 9, for example, the display control unit 135 displays, on a map divided by zones (B zone boundaries), the top 10 zones with the highest number of trips and the top 10 zones with the highest number of trips. A display screen 27 is generated for displaying the color by color. Further, the display control unit 135 displays, for example, the secondary mesh No or road link ID corresponding to the specific point or range on the accepted road as the designated point 28 on the display screen 27. The display control unit 135 displays the movement route of each vehicle 5 passing through the designated point 28 as, for example, the thickness of a line corresponding to the number of vehicles 5. As a result, the map display system 1 can easily display for each vehicle 5 passing through the designated point 28 which zone is often used as a departure or arrival place and which road is often passed. it can. In other words, the display screen 27 can determine at a glance what route the vehicle 5 that passes through the designated point 28 is carrying a load from which zone to which zone.

  In addition, the display control unit 135 may display, for example, for each departure place or arrival place on the display screen 25 or 27, that is, display only the departure place or only the arrival place. Further, the display control unit 135 may display on the display screen 25 or 27 the departure point, the arrival point, the movement route, and the like of the vehicle 5 that match the conditions received by the reception unit 133.

The terminal device 10 displays the received selection screen on a display unit (not shown), and transmits the survey point or range selected by the analyst, that is, a specific point or range on the road to the server device 100 as selection information. When receiving the selection information, the reception unit 133 of the server device 100 receives a selection of a specific point or range on the road (step S1). The receiving unit 133 outputs the road link ID on the digital map of the position information of the specific point on the received road or the secondary mesh No of the received range to the specifying unit 134.

  When the secondary mesh No or the road link ID is input from the accepting unit 133, the specifying unit 134 refers to the route data storage unit 124 and extracts the corresponding trip No (Step S2). Further, when each condition is input from the accepting unit 133, the specifying unit 134 refers to the vehicle master 122 and the route data storage unit 124, and extracts a trip number reflecting each condition.

  The identification unit 134 refers to the OD data storage unit 123 based on the extracted trip No., and identifies the trip start zone and the trip end zone (step S3). The specifying unit 134 outputs the specified trip start zone and trip end zone to the display control unit 135.

  When the specified trip start zone and trip end zone are input, the display control unit 135 counts the number for each zone. The display control unit 135 generates a display screen in which, for example, zones on the map are color-coded according to the number of cases (step S4). The display control unit 135 transmits the generated display screen to the terminal device 10 via the communication unit 110 or the like, and displays the display screen on a display unit (not shown) of the terminal device 10 (step S5).
