Provision of information support by pedestrian-to-vehicle communication system

We propose a prototype of pedestrian-to-vehicle communication system using both 3G wireless network and wireless LAN for improving pedestrian safety. The system can exchange information between pedestrians and vehicles and give information support to drivers and pedestrians by estimating the collision risk between each pedestrian and vehicle. The effectiveness of information support was verified by a sensory test. The result of an experiment in an intersection where visibility is bad showed that the optimal timing for information provision differs between the pedestrian and the driver and depends largely on the traveling direction of the vehicle and the pedestrian at the intersection.
