Abstract:

To reduce the delay of left-turning buses and improve the traffic efficiency at signalized intersections, a novel variable bus approach lane(VBAL)control method based on bus pre-signals is proposed. This method combines the variable lane with the bus priority pre-signal, and realizes the left-turning bus priority without causing great impact on other vehicles. To validate the effectiveness of the method, the VBAL scheme was compared with the single left-turn lane scheme(SLTL)and the double left-turn lane scheme(DLTL). On this basis, the delay change calculation model of left-turning buses and through vehicles were established by the cumulative curve graphic method. The influence of vehicle proportion and green split on the model was studied through sensitivity analysis. The results show that VBAL can reduce the delay of left-turning bus and the increase of through vehicle delay to the greatest extent. Finally, the scheme was applied to a real-world intersection, and the results demonstrate the effectiveness and advantage of the VBAL scheme.
