Description

また、第１１の発明は、歩行者が携帯する歩行者端末装置との間で歩車間通信を行う車両の車載端末装置において歩行者の軌跡を表示する軌跡表示方法であって、衛星測位により車両位置情報を取得し、前記歩行者端末装置から送信される無線信号から歩行者位置情報を取得し、前記車両位置情報と前記歩行者位置情報とに基づいて、前記車両の進行方向に対して横断する位置にいる歩行者の有無を判定し、横断する歩行者がいると判定された場合に、前記横断する歩行者の移動を軌跡として、前記車両の運転者の視認可能な位置に映し出すものとする。 An eleventh aspect of the invention is a trajectory display method for displaying a trajectory of a pedestrian in an in-vehicle terminal device of a vehicle that performs inter-pedal communication with a pedestrian terminal device carried by the pedestrian. Acquires position information, acquires pedestrian position information from a radio signal transmitted from the pedestrian terminal device, and crosses the vehicle in the traveling direction based on the vehicle position information and the pedestrian position information. The presence or absence of a pedestrian in the position to be determined , and when it is determined that there is a pedestrian crossing, the movement of the crossing pedestrian is taken as a trajectory and projected to a position visible to the driver of the vehicle; To do.
