摘　　要：全向行人过街交叉口这种行人过街形式的关键是有1个行人专属相位,此时4个方向的车辆相位都为红灯,行人不但可在传统四方向穿行并且可在新设计的对角斜向方向自由行走.全向干线协调,即是道路干线中包含全向交叉口的干线协调.本文研究了全向干线协调成本模型,讨论了评价指标选取及目标函数构建时的具体思路,结合全向行人过街交叉口特性和实际情况,对传统设计干线协调控制方案进行改进,结合传统韦伯斯特公式,提出1种新的周期时长计算方法;构建干线协调控制适用性模型,用约束条件设限,确定了全向干线协调最小成本前提下的最优信号配时.利用VISSIM软件仿真对比,对得到的仿真评价数据进行分析,验证了模型的有效性.Exclusive pedestrian phasing allows pedestrians to cross the intersection in all directions while vehicular traffic is stopped.The arterial coordination of exclusive pedestrian phasing is the arterial coordination for intersections with exclusive pedestrian phasing.In order to study the coordination cost model for these intersections,this paper discusses the specific ideas for the selection of evaluation indicators and the construction of the objective function.Combined with the characteristics of exclusive pedestrian phasing and the actual situation,the traditional design trunk line coordination control scheme is improved;combining with traditional Webers Special formula,this paper proposes a new calculation method of cycle duration.It constructs the applicability model of trunk line coordination control,sets limits with constraint conditions,and determines the optimal signal timing under the premise of the minimum cost of trunk line coordination.Using VISSIM software simulation comparison,the simulation evaluation data obtained is analyzed,and the validity of the model is verified.
