    • PROBLEM TO BE SOLVED: To provide a route search system, a route search apparatus, a route search method, and a computer program, which enable a user to search a route more suitable for the user.SOLUTION: A route search method includes: specifying an area including a link for each of plural links constituting a route from a start point to a destination; acquiring an area cost calculation condition that correlates an element influencing a search cost for each area with a calculation condition of a search cost for a link including the element and predicting a clock-time of a vehicle arriving at the link; obtaining a traffic condition of the link at the arrival clock-time as an element influencing the search cost; and specifying a suitable route from the start point to the destination for each search condition by using the search cost calculated on the basis of the specified area, the area cost calculation condition correlated with the area and the element such as the traffic condition.
    • 要解决的问题:提供一种路由搜索系统,路径搜索装置,路径搜索方法和计算机程序,其使得用户能够搜索更适合于用户的路由。解决方案:路由搜索方法包括:指定 包括构成从起点到目的地的路线的多个链接中的每一个链接的区域; 获取将影响每个区域的搜索成本的元素与包括所述元素的链接的搜索成本的计算条件相关并且预测到达所述链接的车辆的时钟时间的区域成本计算条件; 在到达时钟时间获取链路的交通状况作为影响搜索成本的因素; 并且通过使用基于指定区域计算的搜索成本,与该区域相关的面积成本计算条件以及诸如交通状况的要素,为每个搜索条件指定从起始点到目的地的适当路线。

    • PROBLEM TO BE SOLVED: To reduce the time required for searching a route, while maintaining the quality of the route obtainable through route search.
      SOLUTION: A navigation apparatus for searching for a route from a departure place up to a destination includes: an information storage means (3) for storing map data of hierarchical structure; a route search means (4a) for reading the map data of hierarchical structure from the information storage means, searching for routes inside predetermined areas on the departure place side and on the destination side respectively, and obtaining a shortest cost route in the overlapping area of these search areas; and a control means (4b) for controlling the search by the route search means. The control means updates the cost of the shortest cost route, when the cost of a shortest cost route, obtained by searching up to a higher level of the hierarchy, is lower than the cost of the shortest cost route obtained.

    • PROBLEM TO BE SOLVED: To set up proper retrieval routes for readily making a vehicle run.
      SOLUTION: This route guide system has an entering lane acquisition processing means for acquiring one link, entering a crossing as an entering road and acquiring one lane of the entering road as an entering lane; an exiting lane acquisition processing means for sequentially acquiring one of the links, other than the entering road of each link connected to the crossing as an exiting road and sequentially acquiring each lane of the exiting road as an exiting lane; a lane movement determination processing means for determining whether there is any lane movement, when entering the crossing from the entering lane and exiting into the exiting lane; a road length determination processing means for determining whether the road length of the link at which the lane movement is performed is shorter than a threshold value, when there is lane movement; and a cost calculation processing means for adding costs of the lane move, when the road length is shorter than the threshold.
