Abstract(J) | TTCとTHWは追突リスク指標として一般的に用いられている.しかし,数式が簡単である分,使用できる走行条件が限られる.一方,衝突回避加速度ACAは数式が複雑な分,使用できる走行条件が多い. 走行車両の危険度を示すのに,TTCやTHW,ACAのいずれを用いるべきかを的確に判断するために,三者の統一的な見方を提案する. Translation |
Abstract(E) | TTC(Time to collision) and THW(Time headway) are commonly used as collision risk indicators. However, these formulas are simple, the driving conditions that can be used are limited. On the other hand, the acceleration for collision avoidance ACA has many driving conditions that can be used due to the complicated mathematical formula. We proposed a unified view of the three indicators in order to accurately determine whether TTC, THW, or ACA should be used to indicate the degree of risk of a moving vehicle. |
