Pedestrian Collision Risk Assessment Method of Right Turn at Intersections Considering Drivers’ Risk Anticipation of Traffic Environment Transition (First Report)

- Typical Pattern Classification of Pedestrian Collision Scenes and a Case Study on Car-following Right Turn Scenes -

Abstract

Towards prevention of traffic accidents involving pedestrians, the objective of this study is to construct a pedestrian collision risk assessment method of right turn at intersections for driver assistance systems based on driving behavior indices related to drivers’ risk anticipation. In this paper, we first clarified traffic environment elements affecting right turn driving behavior and classified typical patterns of pedestrian collision scenes. Next, we focused on car-following right turn scenes as a case study and examined driving behavior indices regarding drivers’ risk anticipation and validated the indices through a risk scene reproducing experiment using the JARI-ARV.
