The Influence of Traffic Environment on Collision Risk Assessment Based on Right-Turn Driving Behavior at Intersections

Abstract

In this study, the influence of traffic environment on collision risk assessed by driving behavior indices of right turns at intersections were investigated. A driving simulator (DS) experiment and a risk simulation using the data obtained in the DS experiment were performed to investigate the influence. As a result of the investigation, the influence of the traffic environment on the relationship between the driving behavior indices and collision risk was clarified. Moreover, factors related to the influence, and a solution to consider the influence in risk assessment methods were discussed.
