Development of a high-functionality tail lamp system in the second phase of the ASV program

A high-functionality tail lamp system aimed at reducing the risk of rear-end collision was developed and installed on the ASV-2, prototype vehicle produced in the second phase of the Advanced Safety Vehicle program promoted by the Ministry of Land, Infrastructure and Transport of Japan. This paper presents experimental findings concerning basic driver cognition and response behavior in connection with stop lamp illumination and approach to a preceding vehicle. It also describes the main functions of the system comprising an emergency braking advanced advisory and large high-mounted stop lamps.
