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

- Environmental Elements Affecting Drivers’ Driving Behavior Selection and Pedestrian Collision Risk -

Abstract

Towards prevention of traffic accidents involving pedestrians, the objective of this study is to construct a pedestrian collision risk assessment method of right-turns at intersections based on driving behavior indices related to drivers’ risk anticipation for driver-assistance systems. In this paper, first, environmental elements that affect driving behavior was selected based on naturalistic driving data. Next, the influence of the environmental elements was examined by a risk-scene reproducing experiment. Results showed that road width affects collision risk assessment and collision risk of different road width conditions could possibly be evaluated by additional consideration of vehicle position and direction.
