| Abstract: | According to the theory of cellular automata(CA),the urban traffic flows at 4 intersections were investigated and a set of discrete equations were proposed to describe the traffic dynamics.The effect of two signal control strategies,i.e.,synchronous timing control and actuated control,on traffic flow were discussed.Simulation results show that(1) the effect of signal control strategies is related to the density of traffic flow;(2) and there exists a certain range of actuated control parameters in which the ... |
