Even so, it is related to a route map display device, a route map display system, a route map display method, and a route information distribution server that display a currently operating route portion in real time so that a departure station and a destination station can be designated. It is.

  2. Description of the Related Art Conventionally, navigation devices and navigation systems that guide a user by searching for a route from a desired departure point to a destination using map data and road data are known. Such navigation devices and navigation systems are known. As a car navigation device that is installed in an automobile and guides the route to the driver, a communication type that uses a mobile phone as a navigation terminal to send a route search request to the route search server, receives the result, and receives route guidance Navigation systems have been put to practical use.

  In particular, the communication-type navigation system is a system that uses a mobile terminal such as a mobile phone as a navigation terminal, and is also used as a navigation system for pedestrians. As a navigation system for pedestrians, it is preferable to add a route guidance function including transportation, and in addition to searching and guidance for walking routes, the route search server accumulates routes and operation time data of transportation, There is also a navigation system having a function of guiding a route from a desired departure station to a desired destination station (boarding candidate train) in addition to searching for a walking route and guidance. There is also a traffic guidance system that receives and displays information such as routes, timetables of transportation facilities, and trains that can be boarded from an information distribution server without searching for walking routes.

  A general navigation device, a route search device and a route search method used in a communication navigation system are disclosed in, for example, the following Patent Document 1 (Japanese Patent Laid-Open No. 2001-165681). This navigation system is configured to send information on a departure point and a destination from a portable navigation terminal to an information distribution server, and the information distribution server searches and guides a route that matches a search condition from road network and traffic network data. Has been. As the search condition, there are means for moving from the departure place to the destination, for example, walking, automobile, combined use of railroad and walking, and the route is searched as one of the search conditions.

  The information distribution server has roads (routes) of map data as nodes and nodes as the positions of inflection points, links connecting the nodes as links, and cost information (distance and required time) of all links as a database. ing. Then, the information distribution server sequentially searches for a link from the departure node to the destination node with reference to the database, and traces the node and link with the smallest cost information of the link as a guide route. The shortest route can be guided to the portable navigation terminal. As such a route search method, a method called label determination method or Dijkstra method is used. Patent Document 1 also discloses a route search method using this Dijkstra method.

  A route search system that searches for routes that use transportation is a database of operation time data of each transportation based on route search conditions such as departure date, departure location, destination, arrival time specified by the user. It has a time database and data that makes the traffic network a database based on this. Then, referring to these databases, each available means of transportation (individual trains and route buses) connecting the departure point and destination, including connections (transfers), is sequentially traced to meet the route search conditions. It is configured to present one or a plurality of candidates for a guide route (departure station, destination station, route, train, etc.). As route search conditions, it is generally possible to specify conditions such as required time, number of transfers, and fares.

  In addition, as a system for conducting searches and guidance related to transportation facilities, a terminal device such as a mobile phone is connected to an information distribution server for guiding route information and timetable information of transportation facilities, and a desired departure station, departure time, destination station, etc. There is also provided a guidance system that can specify information, receive information on routes, trains, trains and other transportation means that can be boarded, and display them on a terminal device. In general, when such use is performed from a terminal device, address information such as a URL (Uniform Resource Locator) or a domain name for specifying a location where information to be downloaded exists is input to the terminal device and specified by the address. The information distribution server (information site) is accessed to download desired information.

  The route search data in the navigation system for route search and route guidance using the transportation system is the same as the road network data in the in-vehicle navigation system and the pedestrian navigation system. In addition to data networked as a two-way link, the operation time and required time of each link are added as link cost data for each means of transportation operated on each traffic route. Furthermore, there is a system in which fare data is added and the fare of the searched guide route is guided together.

  Therefore, the guidance route data distributed to the terminal device includes a route search condition specified by the user, such as a route route from the departure point to the destination, and buses, trains, trains, and times that guide the ride, and the operation. A timetable or a so-called station pasted timetable posted at a station is processed as it is or into a format such as display data that can be displayed on a necessary part, and distributed to the terminal device. The terminal device can check the route and the transportation means to be boarded by displaying the guidance route data, the operation timetable, or the station pasted timetable.

  A route search method for performing a route search using a transportation facility is disclosed as a traffic network route search method in, for example, the following Patent Document 2 (Japanese Patent Laid-Open No. 2000-258184). The traffic network route search method disclosed in Patent Document 2 expresses a traffic network from a starting point to a destination point by using a node as a point and a link between points as a link. It is a traffic network route search method that searches under conditions.

  In this method, as the route from the departure point and destination point to the transportation station to be used, the straight distance from the departure point and destination point to the transportation station to be used, and from the destination point to the transportation station to be used. The average distance is calculated using latitude and longitude information as a variable, the average cost is calculated using the linear distance as a variable, the stations of all the transportation facilities included in the cost range specified by the average cost are determined, and the walking route The total walking network is expressed by incorporating the obtained walking route into the traffic network route of the transportation system, and the search is performed under the cost condition obtained by the label determination method using a computer.

  Patent Document 3 below (Japanese Patent Laid-Open No. 9-198530) discloses a route search system that searches for and displays an optimal route using a pen computer. In the route exploration system, a route map is displayed on a display, and a starting point and a destination are designated by touching the map with an electronic pen. In response to this, the computer searches the database storing route information, fares, required time, etc., calculates the optimum route route that can be reached in the shortest time and at the lowest price, and uses the route in that route. The station is displayed on the display.

  Non-Patent Document 1 (Station Search Club, “Station Search Lab Station Map”) provides a route search service on the Internet homepage. In the route search service, a route map is displayed, and a starting point and a destination are designated by clicking on the map with a mouse. Based on this information, a database that stores route information, fares, required time, etc. is searched to calculate the optimum route route that can be reached in the shortest time and at the lowest cost, and the route and transfer station used in that route. Is displayed on the display, as well as a map around the transfer station and destination station, station area information, and advertisements for stores near the station.

  Next, drawing processing in the route map display system of the present invention will be described with reference to the flowchart shown in FIG. First, as an initial screen, as shown in FIG. 4, all the route displays between stations are deleted from the route map of FIG. 3, and a route map in which only the station is left is drawn (step S1). This screen shows that there is no route that is currently in operation in the time zone before the first power train departs after the last train ends.

  Next, based on the timetable data in the timetable database 27, it is determined whether or not the operation of the first power generation vehicle has started on any route (step S2). If the operation of the first power generation vehicle has not yet started, step S1 is performed. Return to, and continue drawing the route map that leaves only the station.

  On the other hand, when the operation of the first power generation vehicle is started in step S2, as shown in FIG. 5, the drawing of the route is sequentially started from the first departure station, and is gradually extended according to the timetable data in an animated manner as time passes ( Step S3). Finally, an entire route map as shown in FIG. 3 is drawn (step S4).

  After that, it is determined whether or not the last train on the service line has departed and the service has been completed (step S5). When the service has been completed, the route of the service line is deleted and the train on the timetable is displayed. Erasing is sequentially performed according to the progress (step S6).

  Next, it is determined whether or not the last train has started on each route and the operation of the last train has been started (step S7). When the last train operation has started, the routes are sequentially erased in an animated manner according to the progress of the last train. (Step S8). Finally, as shown in FIG. 4, all the route displays between the stations are erased, and a route map in which only the stations are left is drawn.

  In addition to the basic drawing process as described above, the route drawing means 25 stores the current train congestion status of each route, the suspension status of trains due to accidents, breakdowns, etc. By using the operation status data, it is possible to draw a section where the train is congested or a section where the train is suspended due to an accident, a failure, or the like, or a section where the operation is troubled so as to be distinguishable from other sections. For example, in FIG. 6, the section between J and K stations is thickened to indicate that the section is congested, or the bulge is added between L and M stations, and the train stops in that section. Or, it can indicate that there is a traffic obstruction.

  In each figure, the up and down routes are displayed simultaneously, but two up and down routes may be displayed separately. Further, a station frequently used by the user or any other station may be displayed as a base point. In that case, the base station may be set by display setting or the like.

  The route map drawn by the route drawing unit 25 in this way is edited as distribution data by the distribution data creation unit 23, distributed to the terminal device 10 via the distribution data creation unit 22, and displayed on the screen. Then, the user designates the departure station and the destination station on the route map.

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. 9, 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. 9, 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. 9, 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. 9, 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. 9, 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. 10, 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. 10, Nn (◯ mark) and Nm (◎ mark) indicate nodes, Nm (◎ mark) indicates a transit point (such as a transfer station) of 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. 10, 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. However, in the traffic network, as shown in FIG. 10, trains and airplanes (hereinafter referred to as individual trains and airplanes) that operate traffic routes are used. 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. 10, 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. Therefore, 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. 10, 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 route drawing means, route search and route map display can be performed only by the user terminal as a 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.

  As described above in detail, according to the present invention, since a route map showing a route in service at that time is displayed in real time according to the time, which section of which route can be found in the early morning or late at night. You can see at a glance whether it is currently in service. For this reason, it is possible to provide a route map that is easy to see and understand for everyone, and it is possible to appropriately select the starting point and destination for route search.
