As the uncertain characteristics of traffic flow in urban expressway, fuzzy control can be used as an effectual way to solve traffic problem. A fuzzy controller of signal intersection is designed for alleviating traffic congestion downstream off-ramp at the Surface Street. The overtime of green-light and the next time for green-light phase are optimized according to the queue lengths and the numbers of phase delay, and the method corresponds to a man’s decision-making process. Simulation research based on MATLAB program design is carried out and the results show that the methods are promising and the fuzzy controller have a better performance for congestion mitigation downstream off-ramp of urban expressway.
