Research on Automated Driving Traffic Flow Based on the Cellular Automata Model

In this paper, a cellular automaton traffic flow model based on automatic driving of a single lane is proposed, which is based on the Arnab Bose automatic driving model and combined with the classic NS model. The running situation of automatic driving vehicle was analyzed by simulation with MATLAB. The study found that the character of the traffic flow in the automatic driving environment is present. The study also found that setting different headway in the automatic driving has a great impact on the road traffic capacity. The headway of 0.5s capacity is about 4 times the headway of 3S capacity, when the headway is reduced from 4S to 1s when the traffic congestion can be reduced by about 95%, which can be used as an important strategy of traffic congestion mitigation.
