Dynamic signal control strategy for intersection near a highway-railway at-grade crossing

摘要

To decrease the influence of train passage on the efficiency of the intersection near a highway-railway at-grade crossing, this paper proposes a signal control strategy that dynamically applies two fixed signal timings and a priority phase based on the different scenarios, including two rules for judging different scenarios and two signal timings. The rule for judging whether a train is crossing a highway-railway at-grade crossing or not is established by using detected information. The rule for judging whether the influence of train passage is eliminated is designed according to train passage time and signal cycle length with the influence of train passage. Signal timing parameters for traffic flow, with and without the influence of train passage are respectively optimized by the ARRB method. The simulation results indicated that the performance of the dynamic strategy is superior to the performance of the two fixed signal schemes.
