PROBLEM TO BE SOLVED: To provide a route guidance technique capable of heightening the possibility of taking a seat in a train.SOLUTION: A navigation system according to the present invention comprises a storage unit in which route information indicating the state of linkage of each station is stored, and a search unit for referring to the route information and searching for a route from one's station of embarkation to one's station of disembarkation. When the one's station of embarkation is a station where one has difficulty taking a seat in the train, the search unit specifies a seat-taking possible station where there is high possibility of taking a seat in the train, and searches for a route leading to the one's station of disembarkation from the one's station of embarkation via the seat-taking possible station.

    【課題】列車に着席できる可能性をより高めることのできる経路案内技術を提供する。【解決手段】ナビゲーションシステムは、各駅のつながり状態を表す路線情報が記録された記憶部と、路線情報を参照して、乗車駅から降車駅までの経路を探索する探索部と、を備える。探索部は、乗車駅が、列車の座席に着席することが困難な駅である場合に、列車の座席に着席できる可能性が高い駅である着席可能駅を特定し、乗車駅から着席可能駅を経由して降車駅に至る経路を探索する。【選択図】図1
