Chain collision accident: Causes and avoidance techniques

Abstract

This chapter reports on the chain of collisions that occur in case of emergency deceleration in a platoon of vehicles driving in a convoy. Chain Collision Avoidance applications are a new emerging means of reducing the number of chain accidents on the road by providing cars with collaborative communication capabilities, thus allowing them to react against the real risk of accident which may occur in different traffic circumstances. This chapter evaluates the Chain Collision Avoidance application under a wide range of parameters (time headway, reaction time, and recommendation speed) and measures the impact of each parameter on the number of collisions under different market penetration rates. In this chapter, an analytical model combined with extensive simulations is developed to investigate the impacts of low market penetration rate on the number of collisions.
