信号交叉口第一辆车到达分布及影响因素分析
Analysis on the Arrival Distribution and Influencing Factors of the First Car Arrival at the Signalized Intersection
摘要
Abstract
Signalized intersection delay was one of the core parameters in intersection design and evaluation of service level, and analyzing the first vehicle′s arriving could help to analyze the intersection delay. Firstly, the features of the first vehicle were probed based on time difference between arriving time of the first vehicle and the start of the red time. Considering the factors that could impact the vehicle′s arriving, the orthogonal experi-ment was used to optimize the experiments′combination. Using the validated through lane of the signalized in-tersection to simulate the orthogonal experiments, it was proved that the order of the factors impacting the first vehicle arrival during red indication was the saturation, types of vehicles arrival, intersection spacing, the split, the saturated flow, and the bus ratio. Finally, for the interaction phenomenon of saturated flow and satu-ration, using transactional analysis to analyze, the results was: when the saturated flow was 1650 Passenger Car Unit/Hour ( pcu·h-1) , and the saturation was under 0.25, there was the highest level of impact on the first vehicle′s arriving.关键词
