Abstract

Using the cellular automata Nagel–Schreckenberg (NaSch) model, we numerically study the impact of traffic lights on the probability of car accidents (Pac) at the intersection of two roads. It is found that, the probability Pac is more stable with variation of the green light (T) when the symmetric lights are adopted. Moreover, simulation results show the existence of a critical time Tc, below which (TTc) the growing of α has for effect the decrease of Pac. Furthermore, the decrease of Pac is almost always accompanied by a loss of the flux, especially with asymmetrical lights. To overcome this problem, we proposed a strategy that can greatly increase the flux and keep the probability Pac as small as possible, especially for the low and high injection rates.
