Compared with the time zone of the departure point S determined by 34, the neighboring nodes belonging to the same time zone as the time zone of the departure point S are extracted. In this example, since the time zone of the departure point S is determined to be GMT-8, neighboring nodes Ns0 to Ns4 belonging to the same time zone are extracted as search starting nodes.

- the route searching means 38 reads the reference timetable data and Using the traffic network data, for each combination of the start node and the end node, a route between both nodes is searched for a plurality of candidate routes. Since the searched time information of the route is naturally expressed in the reference time, the time conversion means 40 determines the route time information based on the time zone to which the departure point S or the destination point G belongs. This is converted into the local time of the time zone and provided to the terminal device 20.
- the route search server 30 normally selects the optimum route between the departure point S or the destination point G and the neighboring node (starting node or ending node of the route section using the traffic network) extracted by the node extracting unit 36. If it has the road network data, it is possible to search using the road network data, so that the walking route between the departure point S and each neighboring node and the destination point G and each neighboring node is searched. Thus, a total route search between two points from the departure point S to the destination point G is possible.

Time required to reach the node (station) at the other end of the link.
- individual links may not necessarily link to adjacent nodes. 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 link cost between nodes may differ depending on the transportation means.
- 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.

- the route search is performed using the time / timetable data) (step S102). Since the arrival time at the destination point obtained at this time is the reference time, it is converted to the local time using the time zone information of the destination point (S103).
- the neighboring nodes are a predetermined number of nodes in the order of the distance from the starting point or the destination point, but the method for determining the neighboring nodes is not limited to this.
