Influences of a Safety Assistant Driving Strategy on Microscopic Traffic Characteristics

Abstract

In order to improve road traffic safety caused by driver's subjective factors, safety assistant driving system has become the focus of intelligent transportation research. However, there is little related work to consider safety assistant driving system in microscopic traffic flow to further study its influences. This paper introduces a safety assistant driving strategy into a car-following model to explore the impacts of the assistant driving strategy on microscopic traffic characteristics. The numerical results indicate that the join of safety assistant driving strategy will inhibit the emergence of congestion and reduce the amplitude of the oscillating phenomena, while it will also reduce the maximum traffic flow which affects the capacity of the road.
