To properly determine whether an unblocked section connecting with a blocked section can be passed through and to utilize the determination result for an actual route search.SOLUTION: A blocking information acquisition part 111 of a determination server 1 acquires blocking information, and a specifying part 112 for section etc., specifies, based upon this, a blocked section and an unblocked section connecting therewith. A probe information acquisition part 113 acquires probe information transmitted from a vehicle in the unblocked section within a time range of blocking. A propriety determination part 114 for crossing etc., determines, based upon the acquired probe information, whether it is possible to move from each blocked section to another unblocked section. The determination result is provided by providing means to a terminal device.SELECTED DRAWING: Figure 1
【課題】 当該通行止め区間に接続された非通行止め区間が通行可能か否かを適切に判別し、この判別結果を実際のルート探索に利用できるようにする。【解決手段】 判別サーバ1の通行止め情報取得部111が通行止め情報を取得し、これに基づき区間等特定部112が通行止め区間と、これに接続された非通行止め区間を特定する。プローブ情報取得部113は、通行止めとなる時間範囲において、非通行止め区間上の車両から送信されたプローブ情報を取得する。横断等可否判別部114は、取得されたプローブ情報に基づいて、非通行止め区間ごとに他の非通行止め区間への移動の可否を判別する。この判別結果が、提供手段により、端末装置に提供される。【選択図】図1
