Abstract :
We propose a safe traffic speed control based on safe headway distances in AHS: advanced cruise-assist highway systems. Our proposed method is composed of two layers: calculation of reference speed based on safe headway distances and speed control by a closed loop control system in each vehicle. We show some numerical examples on safe headway distances and speed and this control system can almost control the same traffic capacity as that on conventional highways in Japan. Furthermore, we have designed a safe speed controller so that the closed loop of the system is stable and the step response does not overshoot and we show the effectiveness of our proposed control with “anti reset wind up” by MELROSE, which is a microscopic traffic simulator
