PROBLEM TO BE SOLVED: To provide a pedestrian terminal device that enables power saving in the pedestrian terminal device.SOLUTION: A pedestrian terminal device 2 carried by a pedestrian 1 includes an operation mode selection unit 25b that selects from: a representative terminal operation mode for performing vehicle-pedestrian communication with a vehicle-mounted terminal device 4 on behalf of other pedestrian terminal devices 2; and an intra-group terminal operation mode for performing short-range wireless communication, which has a shorter range and lower electric power than the vehicle-pedestrian communication, with a pedestrian terminal device 2 operating in the representative terminal operation mode. The pedestrian terminal device 2 in which the representative terminal operation mode is selected performs the short-range wireless communication, which has the shorter range and lower electric power than the vehicle-pedestrian communication, with the pedestrian terminal devices 2 operating in the intra-group terminal operation mode, thereby capable of saving power of the pedestrian terminal device itself.SELECTED DRAWING: Figure 2
【課題】歩行者端末装置の省電力化を可能とする歩行者端末装置を提供する。【解決手段】歩行者1が携帯する歩行者端末装置2は、他の歩行者端末装置2を代表して車載端末装置4との間で歩車間通信を行う代表端末動作モード、または代表端末動作モードで動作する歩行者端末装置2との間で、歩車間通信よりも短距離かつ小電力の短距離無線通信を行うグループ内端末動作モードのいずれかを選択する動作モード選択部25bを含む。代表端末動作モードが選択された歩行者端末装置2は、グループ内端末動作モードで動作する歩行者端末装置2との間で、歩車間通信よりも短距離かつ小電力の短距離無線通信で通信するので、自身の歩行者端末装置の省電力化を図ることができる。【選択図】図2
