Abstract Utilizes the fuzzy control concept to design a highway on-ramp control (HORC) such that the traffic light in the on-ramp works well to maintain the smoothness of the traffic flow on the highway. The HORC includes a fuzzy decision base (FDB) to estimate the probability of the light change and a decision function to decide the change making of the light. In this HORC, we only need one sensor to measure the speed and the speed change rate of the vehicles on the highway. Our simulation shows that the HORC has a good performance
