To alleviate traffic congestion caused by excessive left-turning traffic at intersections during peak hours, this paper proposes a signal timing optimization method based on reverse variable lane intersections. First, the operation rules of the reverse variable lane are analyzed. Then a model of the intersection capacity, delay, and vehicle emission of the reverse variable lane is constructed. The intersection signal timing optimization model is developed and solved by genetic algorithm. The operational effect of setting up the reverse variable lane is analysed through the actual intersection. The results show that the intersection capacity is increased by 14.57%, the average vehicle delay and vehicle emissions are reduced by 21.13% and 13.43%, respectively. By setting up variable lanes in the reverse direction and optimizing the signal timing with multiple objectives, traffic congestion and pollutant emissions at the intersection can be largely alleviated and the traffic signal control effect is very good.
