Abstract
In order to enable a driver in driving a vehicle to quickly and assuredly recognize a pedestrian having a collision risk with the vehicle even when it is difficult for the driver to recognize the pedestrian by eyes, such as during night time, an in-vehicle terminal device is configured to: determine a collision risk based on pedestrian position information and vehicle position information; generate turn-on instruction information which, when the pedestrian is determined to have the collision risk with the vehicle, causes an indicator light carried by the pedestrian to be turned on in a prescribed light color; and transmit the turn-on instruction information to a pedestrian terminal device via pedestrian-vehicle communication, and wherein the pedestrian terminal device is configured to: receive the turn-on instruction information transmitted from the in-vehicle terminal device; and turn on the indicator light based on the turn-on instruction information.
