Research on Traffic Signal Control Base on Neural Network

Traffic signal is a measure of traffic command, which distributes right of way to the triffic flow in time domain. Through comparative study between RBF network and BP network, this paper has selected RBF network to control the trffic single. Green Light Interval is decided by the measurement parameters of detector in the actuated signal control. In the usually, the time phase number of the system is set beforehand. When there is not demand for the vehicles passing in the direction of red light, the green light phase works continuly. The system starts the control model until there is demand for the vehicles passing in the direction of red light. The paper builds the model base on radial basis function, simulates in MATLAB and make an analysis of the simulated results.
