PROBLEM TO BE SOLVED: To search a route while stop time at signal intersections is considered sufficiently.SOLUTION: A server 3 compensates for stop time information on signal intersections for which stop time is insufficiently collected and the stop time information is not created since probe cars do not actually pass through the signal intersections or the number of probe cars passing through the signal intersections is relatively small, on the basis of stop time information on the other signal intersections for which the stop time information is created since the number of probe cars actually passing through the signal intersections is relatively large, and transmits traffic information containing the stop time information to a navigation device 4. The navigation device 4 searches a route from a departure to a destination using the traffic information received from the server 3.

    【課題】信号交差点での停止時間を十分に考慮した経路を探索する。【解決手段】サーバ3は、プローブカーが実際に通過せずに又は通過した台数が比較的少なく、停止時間の収集が不十分で停止時間情報が作成されていない信号交差点の停止時間情報を、比較的多くの台数のプローブカーが実際に通過して作成された他の信号交差点の停止時間情報に基づいて補完し、停止時間情報を格納した交通情報をナビゲーション装置4に送信する。ナビゲーション装置4は、出発地から目的地までの経路を、サーバ3から受信した交通情報を用いて探索する。【選択図】図1
