- Abstract
In this paper, a variable speed limit control approach for improving the efficiency of signalized intersection is proposed from the cyber-physical view. In the proposed control scheme, vehicle-to-vehicle communication is being utilized fully such that the preceding vehicle’s optimal information is exploited for optimizing the motion of the current vehicle. To prepare the control scheme for dynamical optimization, nonlinear model predictive control technique is used to optimally control vehicle speed limit and a new traffic model is constructed by considering vehicle dynamics. Moreover, this paper evaluates the influence of communication distance on the traffic. The results show that extending communication distance in the vicinity of signalized intersection can improve vehicles’ average fuel economy.
