Abstract: H-type crossroads in urban areas of narrow lanes place are very easy to see, this paper sets up N-S cellular automata model as the foundation, in the open boundary conditions, the traffic vehicle redirecting probability produces certain effect to interference with intersection, and so as to  build up the H-type cellular automata model. Through the research to redirecting probability and characteristics influence of traffic lights setting to traffic flow, it points out that among the influence of phase change point position and redirecting probability and the average velocity is closely related, traffic lights timing differences can reduce vehicle interference to increase traffic flow, at the same time, it analyzes the critical redirecting probability of traffic flow in controlling significance.

Key words: redirecting probability, H-type cellular automata, two-way traffic flow, green wave
