Traffic Guiding Method Based on Actuated Control and Phase Jump

Abstract

In the process of conventional traffic control, it often occurs that no vehicles run on a lane when the lane gets a right of way, which lengthens the vehicles waiting time and brings down the guiding efficiency. To get rid of this drawback, this paper proposes a traffic guiding method based on actuated control and phase jump. Time to make a phase jump is decided by the obtained knowledge of queued vehicles. For a light traffic, this paper has deduced the dynamic green time, designed a detector and achieved signal timing by the actuated guiding algorithm; For an almost saturated traffic, the maximum green time and cycle length are restricted by Webster-Monte Carlo Simulation. From the comparison of principles and applications of different guiding strategies, it is found that the method proposed in this paper has a better performance in guiding traffic flow than the existing actuated guiding strategy and the adaptive guiding strategy.
