A direct vehicle-to-pedestrian communication system that can alert pedestrians or drivers in appropriate situations and with suitable timing to reduce traffic accidents involving pedestrians is being developed through the contract research and development scheme of the Ministry of Internal Affairs and Communications at the Cross-ministerial Strategic Innovation Promotion Program. Based on past pedestrian accident analysis results, we focused on scenes that should be handled preferentially. Development of a safety support application with a target of a normal operation rate of safety support function of 80% or more and unnecessary support function of unnecessary operation rate of 20% or less is conducted. We developed prototypes of rucksack type terminals. For the large-scale demonstration experiment of 2018, we conducted a preliminary verification in a public road at Odaiba and was able to confirm that the safety support application operation rate for pedestrians and drivers achieves the target rate. We examined safety support technology that can provide appropriate support and confirmed its effectiveness.
