摘　　要：为提高公交优先的运行效率,研究具有锯齿形公交专用道的公交优先自适应控制策略。对信号交叉口设置预信号,以自适应控制基本原理及逻辑规则为理论基础,根据交叉口各进口道的车辆实时到达率,实时确定各相位绿灯时间及相序,提出一种基于逻辑规则的锯齿形公交优先自适应控制策略,从而更好地实现公交车辆的"时间"与"空间"优先。并通过建立VISSIM仿真模型,对基于逻辑规则的锯齿形公交优先自适应控制策略进行验证分析,结果表明:该策略实施后,公交车车均延误可减少25.05%,社会车辆车均延误可减少5.58%,公交优先效果明显,同时对社会车辆的运行并未造成负面影响。In order to improve the operation efficiency of bus priority,adaptive control strategy for jagged bus priority was studied.In order to realize ＇time＇ and ＇space＇ priority for buses,the advanced signal timing was set for the signalized intersection,and on the basis of adaptive control principle and logical rules,the green time and phase order was determined by the vehicles arrival rates of each entrances.And adaptive control strategy for jagged bus priority was proposed.The bus priority control strategy was validated through the establishment of VISSIM simulation model.The results show that average delay of buses reduces 25.05%,social vehicles average delay reduces 5.58%.The effect of bus priority is obvious,and has no adverse impact on other social vehicles.
