Effect Evaluation of Vehicle-Infrastructure Cooperative Right-Turn Collision Prevention System

Abstract

Right-turn accidents have occurred most often in the signalized intersection accidents. For preventing these right-turn accidents, we are working on research and development of a right-turn collision prevention system using the 700MHz band infrastructure-to-vehicle communication. In order to put into practical use the system, the effect evaluation is important. Therefore, we carried out a 101-person field operation test, and analyzed the obtained data, and quantified the effect of the system. In this paper, we will report about evaluation method we've considered for quantification.
