Nonlinear Dynamical Characteristics of the City Main Road Traffic Flow under the Traffic Lights Delay Control


A traffic flow model for the city main road is established under the traffic light delay control, in which the dynamic behavior of the traffic flow is studied. The master expression of the arrival time is derived in terms of nonlinear maps with three dimensionless parameters: cycle time, offset time and acceleration. The impact of traffic lights delay control is investigated by analyzing the variation process of travel time. Utilizing the Matlab software, the nonlinear dynamic motion of a vehicle moving through the traffic lights is shown in the simulation. The results are explained reasonable in theoretically with real traffic flow.
