Pedestrian terminal device that can save power consumption. The pedestrian terminal device carried by a pedestrian is provided with an operation mode selector for selecting one of a principal terminal operation mode wherein a pedestrian-vehicle communication with an in-vehicle terminal device is performed representing other pedestrian terminal devices, and an in-group terminal operation mode wherein a short-range wireless communication of a shorter range and a smaller power output than the pedestrian-vehicle communication is performed with another pedestrian terminal device operating in the principal terminal operation mode. Because the pedestrian terminal device in which the principal terminal operation mode is selected communicates with other pedestrian terminal devices operating in the in-group terminal operation mode via the short-range wireless communication of a shorter-range and a smaller power output than the pedestrian-vehicle communication, the power consumption of the pedestrian terminal device can be saved.
