Abstract :
In this paper, a fuzzy traffic density homogenizer is proposed to alleviate or avoid the congestion by smoothing the traffic density distribution profile over the freeway. The proposed fuzzy traffic density homogenizer consists of two parts which are fuzzy mean speed controller and fuzzy on-ramp controller. The fuzzy mean speed controller is designed to determine the evolution rate of the mean speed in each section to achieve smooth traffic flow and the fuzzy on-ramp controller is designed to determine the maximum allowable on-ramp traffic volume in the sense that the on-ramp traffic flow does not lead to an amplification of the congestion of freeways
