Abstract: The way in which the traffic signal operates has directly affected the capacity, the crossing delay and other aspects of the urban road intersections. In view of the setting of twice crossing in the intersections which use the all-in-one design for the nonmotorised transport, this paper analyzes the influence of the signal operating modes on mobile, bicycle and pedestrian crossing. By the research of the signal operating modes on transportation management , signal cycle length, vehicle delay, pedestrian delay and so on, together with the qualitative and quantitative analysis based on the intersection geometric characteristics and the traffic flow , we propose an improved intersection signal operating mode , which has more advantages at making full use of the intersection layout , reducing the crossing delay of the nonmotorised transport, and then provide the more rational proposal for the transportation manager and policy-maker .

Key words: Twice crossing, Crossing signal length, Crossing delay, Phase

摘要： 城市道路交叉口所采取的交通信号运行方式，直接影响着交叉口的通行能力、过街延误等诸多方面。本文针对采用慢行交通一体化设计的交叉口上设置二次过街，分析各种信号运行方式对机动车、自行车、行人过街的影响，通过对各种信号运行方式在交通组织管理、信号周期时长、车辆延误、行人延误等方面进行分析研究，结合现场交叉口几何结构及实际交通状况进行定性、定量分析，提出更有利于充分利用交叉口空间、更大限度减小慢行交通过街延误的交叉口信号运行方式，为交通管理者、决策者提出合理化建议。
