In addition, as a display method of a route map, it may be displayed there by jumping to another page, or another browser may be launched and displayed there. The route search condition specifies a departure station and a destination station on the displayed route map.

  Note that the method for inputting the conditions for route search is not limited to the above method, and a method for designating a point by inputting the POI name, address, and telephone number of the desired point as in a normal navigation system, and the desired point. Various methods such as a method of clicking the POI icon displayed on the map can be adopted.

  FIG. 3 is a diagram illustrating an example of a route map. Each route can be identified by different colors. When performing a route search, after specifying the departure date and time or arrival date and time, if necessary, the departure station and the destination station are designated by clicking on the station mark on the route network as shown in FIG. When the result thus input is edited as route search request data by the distribution request editing unit 16 and transmitted to the route information distribution server 20, the route search unit 24 of the route information distribution server 20 includes the search network database 26, the time An optimum route and a plurality of candidate routes are searched with reference to the table database 27 and the fare database 28.

  Note that whether to search for the optimum route or a plurality of candidate routes depends on the user's preference, and either one may be selected on the route search condition input screen. When a plurality of candidate routes are searched, the candidate route list is displayed in the order of, for example, the shortest required time or the lowest fare, and when the user selects one of the candidate routes, the corresponding candidate route is displayed. Is displayed on the route map. Also in this case, the user can select the sorting order of the candidate routes on the route search condition input screen.

  As a result, when the optimum route or the specific candidate route is determined, the distribution data creating means 23 deletes the route other than the optimum route or the specific candidate route from the original route map and puts the route on the optimum route or the specific candidate route. Image data as shown in FIG. 4 with only a certain route left is created, distributed to the terminal device 10, and displayed on the display screen of the terminal device 10. Here, only the route from the A station to the B line by taking the Q line and changing to the M line at the C station and the N line at the D station is displayed.

  At that time, a large free space is created in the map display area of the screen. Therefore, as shown in FIG. 5, fare information, information about the destination station, advertisements, etc. are displayed in the empty space. The fare information is calculated by the fare calculation means 25, and the station periphery information and advertisement data are extracted from the advertisement / station periphery information database 29 and used. By displaying information related to the route route such as the departure station, the destination station, the fare, the required time, and the transfer station, the user can easily grasp various information related to the route route.

  Next, the flow of processing in the route map display system of the present invention will be described with reference to the flowchart shown in FIG. First, the route information distribution server 20 is called from the terminal device 10, route map data is received and displayed on the screen of the terminal device 10 (step S1). And, for example, if you want to go from station A to station B, click on station A on the route map to determine the departure station (step S2), then click on station B to determine the destination station (step S2). S3).

  Next, a route search request is transmitted to the route information distribution server 20 by designating the departure station and destination station determined in steps S2 and S3, and the route search means 24 of the route information distribution server 20 searches for an optimum route (step) S4). When the optimum route is determined, the distribution data creation means 23 creates a route map in which routes other than the optimum route are deleted from the entire route map (step S5). In addition, display data is created by inserting station peripheral information, advertisements, and the like of the target station in the empty space of the route map created in step S5, distributed to the terminal device 10, and displayed on the display screen (step S6). . Thereafter, it is determined whether or not the “screen reset” button has been clicked (step S7), and if clicked, the process returns to step S1.

The route search by the route search means 24 is performed as follows. For example, when the road is composed of roads A, B, and C as shown in FIG. 7, the end points, intersections, and bending points of the roads A, B, and C are used as nodes, and the roads connecting the nodes are directed links. Link cost data with node data (node latitude / longitude), link data (link number) and link cost of each link (link distance or time required to travel the link) as data Composed.
That is, in FIG. 7, Nn (◯ mark) and Nm (◎ mark) indicate nodes, and Nm (◎ mark) indicates a road intersection. Directional links connecting the nodes are indicated by arrow lines (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the road, but in FIG. 7, only the links in the direction of the arrows are shown for the sake of simplicity.

  When performing route search using such road network data as a search database, follow links linked from the departure node to the destination node, accumulate the link cost, and minimize the accumulated link cost. Search for and guide. That is, in FIG. 7, when a route search is performed with the departure point as the node AX and the destination as the node CY, the road travels from the node AX along the road A, turns right at the second intersection, enters the road C, and reaches the node CY. The link cost is accumulated sequentially, and a route that minimizes the accumulated link cost is searched for and guided.

  Although other routes from the node AX to the node CY are not shown in FIG. 7, there are actually other such routes, so that a plurality of routes that can be reached from the node AX to the node CY are displayed. A search is performed in the same manner, and a route with the lowest link cost is determined as the optimum route. This method is performed by, for example, a known method called the Dijkstra method.

  On the other hand, the railway network data (traffic network data) for route search of transportation facilities is configured as follows. For example, as shown in FIG. 8, in the case of traffic routes A, B, and C, each station (each airport on an aircraft route) provided on each traffic route A, B, and C is a node, and the nodes are connected. A section is represented by a directional link, and node data (latitude / longitude) and link data (link number) are network data. In FIG. 8, Nn (○ mark) and Nm (◎ mark) indicate nodes, Nm (◎ mark) indicates a transit point (such as a transfer station) on a traffic route, and a directional link connecting each node. It is indicated by an arrow line (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the traffic route, but in FIG. 8, only the links in the direction of the arrows are shown for the sake of simplicity.

  However, the traffic network basically has a different link cost compared to the road network. In other words, in the road network, the link cost is fixed and static, but in the traffic network, as shown in FIG. 8, trains and airplanes (hereinafter referred to as individual trains and airplanes) that operate the traffic route. A plurality of means of transportation). The time of departure from one node and the time of arrival at the next node are determined for each means of transportation (specified by timetable data and operation data), and individual routes do not necessarily link to adjacent nodes. There is a case. This is the case, for example, with express trains and trains that stop at each station. In such a case, a plurality of different links exist on the same traffic route, and the required time between nodes may differ depending on the transportation means.

  In the transportation network illustrated in FIG. 8, a plurality of transportation means (routes) Aa to Ac... Exist on the same link of the transportation route A, and a plurality of transportation means (routes) Ca to Cc. Will do. Therefore, unlike a simple road network, the transportation network of a transportation facility has a data amount proportional to the total number of transportation means (routes such as individual airplanes and trains). For this reason, the data of the traffic network becomes a huge amount of data compared to the data amount of the road network. Accordingly, much time is required for route search accordingly.

In order to search for a route from a certain departure point to a certain destination using such traffic network data, all the means of transportation that can be used (ride) when arriving from the departure point to the destination are searched. It is necessary to specify the means of transportation that matches the search conditions.
For example, in FIG. 8, when a specific departure time is designated with the departure point as the node AX of the traffic route A and a route search is performed with the node CY of the traffic route C as the destination, the route operates on the traffic route A. Of the transportation means Aa to Ac..., All transportation means after the departure time are sequentially selected as the departure route. Based on the arrival time at the transit node on the transit route C, among all the transit means Ca to Cc... Operating on the transit route C, all combinations of transit means after the time that can be boarded at the transit node. The total time required for each route, the number of transfers, and the like are guided.

  In the above-described embodiment, an example in which data is exchanged between the terminal device 10 and the route information distribution server 20 via the network 1 has been described. However, a database such as a search network database, a timetable database, and the like is provided on the user terminal side. By providing functions such as route search means and drawing creation means, the route search and route map display can be performed only by the user terminal as the route map display device. In the above embodiment, the case of a train route has been described, but the present invention can also be applied to a route of other transportation such as a bus route.

  According to the present invention, it is possible to provide a visually easy-to-see route map and a route search result, so that it is possible to avoid wondering which route to use even in a region where the user has never been. In addition, it is easy for children and the elderly to see, so there is a possibility that they will not get lost, and the possibility of being involved in a crime inadvertently can be reduced. In the present invention, since an advertisement is also displayed, a new advertising business can be provided.
