- Abstract
Using the cellular automata Nagel–Schreckenberg (NaSch) model, we numerically study the impact of traffic lights on the probability of car accidents ( P ac ) at the intersection of two roads. It is found that, the probability P ac 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 T c , below which (T < T c ) P ac increases as the injection rate (α) increases, however, above which (T > T c ) the growing of α has for effect the decrease of P ac . Furthermore, the decrease of P ac 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 P ac as small as possible, especially for the low and high injection rates.
