以信号交叉口行人相位配时为研究对象,针对信号交叉口行人和机动车对配时要求不一致以及我国行人相位清空时间不足的问题,借鉴HCM中行人绿灯最小时间和行人闪时间的计算公式,利用交通流理论,分析了行人相位和机动车相位关系,并建立了不同情况下行人信号配时方法,尤其是行人绿灯时间的调整方法.讨论了不同中央分隔带形式和宽度的行人过街方式,对计算参数的取值进行了研究,在此基础上,给出了不同情况下建议的行人配时计算模型.
Considering pedestrians and vehicles at signalized intersections have different requirements on the timing of pedestrians and pedestrians in our country have not enough time to clear the pedestrians, this paper uses the formula of pedestrian green time and pedestrian blink time in HCM, Based on the theory of traffic flow, the relationship between pedestrian phase and motor vehicle phase is analyzed and the pedestrian signal timing method, especially the pedestrian green time adjustment method, is established under different conditions.The pedestrian crossing modes with different form and width of central divider are discussed, On the basis of this, the proposed pedestrian timing calculation model under different conditions is given.
