- voice guide data (for example, a voice message such as “This is a 300m intersection. Turn left! / ⁇ ”) will be added to the guidance route data distributed from the route search server 30. In this case, the user is guided by reproducing and outputting a voice message through a speaker.
- FIG. 5 is a diagram showing a case where there are multiple entrances A1 to A5 at the station ST1 on the departure side.
- the route search server refers to the POI attribute information DB 40 of the station ST1 and determines whether there are a plurality of entrances. As shown in FIG. 6, when there are a plurality of entrances A1 to A5 at station ST1, virtual node PNs connected by links having a link cost value of “0” are set from the node positions of entrances A1 to A5. This virtual node PN is temporarily connected to the route search network for route search, and it is not necessary to have location information such as latitude and longitude.
- the route search server searches for the optimum route GR from the virtual node PN to the destination (GO AL).
- the link cost of the link connecting each of the virtual node PN force gateways A1 to A5 is “0” regardless of the actual distance, so the distance between the virtual node PN and the gateways A1 to A5 is virtually equidistant. It is.
- the navigation terminal device 20 can be provided with the route to the destination (GOAL) closest to the destination (GOAL) and the route to the destination (GOAL) among a plurality of entrances A1 to A5 in one route search. .
- FIG. 7 is an explanatory diagram for explaining the concept of such route search.
- Figure 7 shows a route search request from the navigation terminal device 20, where there are multiple entrances A1 to A5 in the POI of the nearest station on the departure side, and multiple entrances and exits G1 on the POI of the destination theme park etc. Shows when G5 is present! /
- the route search server 30 When such a route search request is requested from the navigation terminal device 20 to the route search server 30, the route search server 30 first has a plurality of doorways at the departure side and the destination side. Or by referring to the POI attribute information DB40. If there are multiple doorways, extract each doorway A1-A5, G1-G5. Next, the virtual node setting means 39 sets a virtual node PN1 connected by a link with a link cost of “0” from each of the departure side entrances A1 to A5, and the destination side entrances G1 to G5 also have respective forces. Rin Set virtual node PN2 connected by a link with a cost of “0”.
- the network data editing means 38 temporarily adds the virtual nodes PN 1 and PN 2 to the search network data 35.
- the dotted lines schematically represent the search network, and virtual nodes PN1 and PN2 are added.
- the route search means 33 uses this search network data 35 to search for an optimum route from the virtual node PN1 to the virtual node PN2.
- This search can be performed by a method used in general route search such as Dijkstra method.
- the actual route search range is on the actual search network, but by placing the virtual node PN1 (departure side) and the virtual node PN2 (destination side), the optimum obtained between them
- the route is characterized in that it also specifies the starting point and destination at the same time
- the link costs between virtual node PN1 and each of the entrances A1 to A5 are all equal to "0".
- the link costs between virtual node PN2 and each of the entrances G1 to G5 are all equal to "0".
- the route search the shortest route RT1 from the virtual node PN1 to the virtual node PN2 is obtained, and the departure side entrance A5 and the destination side entrance G1 via the shortest route RT1 are respectively obtained. It is the best entrance / exit on the departure side and destination side.
- route RT1 is centered on the route route of transportation.
- a guide route including the nearest station of the destination G1 entrance / exit G1 is searched, and a walking route is searched until the nearest station force entrance G1 to find a comprehensive guide route RT1.
- Departure power The nearest station entrance / exit on the departure point side, in this case, the route between A5 is searched as a walking section
- the route search server 30 receives route search conditions from the navigation terminal device 20.
- the route search server 30 Upon receiving the route search conditions, the route search server 30 first checks the conditions at the departure side by V in the process of step S11, and by referring to the POI attribute information DB40 for the process of step S12, Judgment of force with multiple POIs on the side. Multiple POIs on the departure side If not, the process proceeds to step S14, and the departure place is determined as the departure place node.
- step S 12 if there are a plurality of POIs on the departure side, the virtual node setting means 39 is connected to each node power of the plurality of POIs with a link having a link cost of “0”. (Departure side) is set and the process proceeds to step S15.
- the route search server 30 checks the conditions on the destination side, refers to the POI attribute information DB40 in the process of step S16, and has the ability to have multiple POIs on the destination side. to decide. If a plurality of POIs do not exist on the destination side, the process proceeds to step S17 and the destination is determined as the destination node.
- step S16 if there are multiple POIs on the destination side, in the process of step S18, virtual node setting means 39 is connected from each node of the multiple POIs with a link of link cost "0"
- the virtual node (destination side) to be set is set, and the process proceeds to step S19.
- the network data editing means 38 temporarily adds the departure-side virtual node and the destination-side virtual node set by the virtual node setting means 39 to the search network data, and the route search means 33 searches for the optimum route from the virtual node on the departure side to the virtual node on the destination side using the search network data to which the virtual node is added.
- step S14 or step S17 the departure point or destination is determined as the departure node or destination node. If it is, the node in the process of step S19 is naturally not the virtual node but the departure node or the destination node is used.
- the route search server 30 distributes the searched guide route data to the navigation terminal device 20 in the process of step S20 and ends the process. .
- the navigation terminal device 20 that has received the guide route data temporarily stores the guide route data in the guide route data storage means 25 and displays a map, a guide route, etc. on the display means 24.
- the configuration has been described in which the virtual node is set with reference to the POI attribute information DB 40 for the theme park having a plurality of doorways.
- the virtual node data is stored in the POI attribute information DB 40.
- the virtual node setting means 39 is stored in the POI It can also be configured to acquire virtual node data from the sex information DB40.
- the route search method according to the present invention described above can be used for various searches where a plurality of destinations or a plurality of departure points are assumed. This is effective when searching for a gas station using car navigation or searching for a combination using pedestrian navigation.
- the search itself can be performed using a conventional algorithm, so even a stand-alone device such as a car navigation system can be implemented without significantly modifying the program.
