Abstract

Since the past year, Hanshin Expressway Company has been studying a method to evaluate the contact risk due to lane changes, targeting straight sections of the expressway without merging, using a wide range of vehicle trajectory data observed from certain positions. Now, as the next step, we propose a method to evaluate the contact risk during merging by probabilistic expression and classify them based on coordinated driving behavior, targeting the vicinity of merging.

阪神高速では、過年度より、定点観測した広範囲の車両軌跡データを用いて、高速道路本線の直線区間を対象に、車線変更等に伴う接触リスクを評価する手法を検討してきた。今般、次のステップとして、合流付近を対象に、合流に伴う接触リスクの評価手法を提案し、リスクの発生前後で採られている調整行動の傾向を整理した。
