摘要： Road traffic system is a complex system in which human participate directly. In this system, human factors play a very important role. In this paper, a kind of control signal has been designated at a given site (i.e., signal point) of the road. Under the effect of control signal, the drivers will decrease their velocities when their vehicles pass the signal point. Our aim is to transit the traffic flow states from disorder to order, and then improve the traffic safety. We have tested this technique for the two-lane traffic model that is based on the deterministic NaSch traffic model. The simulation results indicate that the traffic flow states can be transited from disorder to order. Different order states can be observed in the system, and these states are safer.
