Improving the Applicability of Vehicle Trajectory Data Observed from a Certain Position for Risk Assessment

Abstract

It is possible to evaluate the risk of side contact between vehicles by the all vehicle trajectory data generated from a certain point and adding vehicle shape and direction information to analyze and evaluate driving behavior. The driving environment information that can be acquired by the driver was digitized, and risk avoidance behavior was evaluated using these. This paper reports on a method of preparing additional information improved the applicability of the vehicle trajectory data for risk assessment.
