  • FIG. 11 is a flowchart showing an information utilization example (route search processing example) of the entry information utilization terminal device according to the embodiment of the present invention.
  • the information utilization unit 50 sets the entry number N to 1 (step S51), and searches for a route to the POI using the first entry (step S52). If the starting point is set, the route to the POI is searched for the starting point force, and if the starting point is set, the route at the PO point is also searched if the starting point is set.
  • the POI position is set as the final destination, and the route search to reach the destination is performed in consideration of the starting point, the current position, and the traveling direction.
  • it is checked whether or not the route search has been completed for all the incoming routes (step S53). If it is not finished, the route number N is incremented by 1 (step S54), and the processing returns to step S52.
  • the route search is completed for all the incoming routes (YES in step S53)
  • the evaluation value of each searched route is obtained, and the route with the good evaluation value is selected as the recommended route (recommended route).
  • the approach direction and approach route are displayed on the screen with lines, figures, characters, etc. along with a map, or are guided by voice.
  • a route evaluation criterion for example, a criterion such as selecting a route with a low link cost as a route having a high evaluation value is used.
  • This link cost includes the distance on the route along the PO, the time to reach POI (predicted value), the type of road used (whether or not an expressway is used, etc.), and the number of turns.
  • the overall evaluation value may be obtained by weighting the distance and time.
  • the route with the best evaluation value may be set as the first route and presented. Alternatively, multiple routes with different entry routes It may be displayed on a graphic screen so that a user can select a desired route.
  • the present embodiment it is possible to generate appropriate entry information including the POI position and information on how to enter the POI, and provide POI related information that is useful and convenient for the user.
  • the information user can search for a route (route) suitable for entering the POI based on the entrance information, display the route, and guide how to enter the POI. .
  • the terminal device on the information use side it is not necessary for the terminal device on the information use side to store a large amount of information related to the POI entrance location, traffic restrictions (one-way traffic, right turn or left turn prohibition, etc.), etc. It is possible to reduce the scale of the apparatus configuration and the processing amount.
  • the present invention has an effect that it can provide and use appropriate entry information related to the entry to the POI, and provides an entry information providing apparatus that provides entry information related to the POI, and this This is useful for terminal information use terminal devices that use route guidance and route search based on the route information provided by the route information providing device.

Abstract

Dispositif de communication d'informations de routes d’accès et dispositif utilisant des informations de routes d’accès qui peuvent communiquer et utiliser les informations de routes d’accès appropriées sur une route d’accès à un POI. Le dispositif de communication d'informations de routes d’accès (10) du côté de la communication des informations crée des informations de référence de position qui comprennent des informations pour la spécification d’une route contigüe à une entrée d’un POI comme les places de parking, les informations de spécification de la position de l’entrée d’une route, et les informations représentant la direction d’accès au POI depuis la route, et ensuite le dispositif de communication d’informations sur les routes d’accès (10) transmet les informations créées au côté de réception des informations. Sur la base des informations de routes d’accès, le dispositif utilisant des informations de routes d’accès du côté de la réception des information spécifie une entrée de trajet dans le POI, entraînant l'affichage de la route d'accès sur un écran cartographique ou recherchant un trajet approprié à la route d'accès.
