摘要: 人行横道是一种重要的行人过街设施. 一体式人行横道适宜实施同步二次过街控制,分体式人行横道适宜实施独立二次过街控制. 文中对于单个分体式路段信号控制人行横道,根据行人的时间距离关系,建立了行人最大过街时间计算方法. 对于城市干道沿线的相邻分体式路段信号控制人行横道,根据机动车的时间距离关系,在保证机动车双向绿波效果的前提下,以最小化任意人行横道、任意步行方向的行人最大过街时间的最大值为目标,采用整数非线性规划方法,建立了协调信号配时优化模型. 算例分析结果表明,该模型具有良好的实用性和广泛的适用性.

Abstract: Crosswalks are a kind of important pedestrian crossing facility. It is proper to implement the simultaneous signalization at integrated crosswalks and the separate signalization at split crosswalks. Regarding isolated split midblock crosswalks,a method to calculate the maximum pedestrian-crossing time is proposed according to the time-space diagram of pedestrian movements. Regarding closely-spaced split midblock crosswalks along an arterial,a coordinated signal timing optimization model is constructed by means of the integer nonlinear programming method according to the time-space diagram of vehicular movements. In the constructed model,the maximum of the maximum pedestrian-crossing time in any crosswalk and in any movement direction is minimized without any negative effect on the two-way green waves for vehicular movements. Case studies indicate that the constructed model is of practical value and can be widely applied.

Key words: transportation engineering, midblock crosswalk, coordinated signal control, integer nonlinear programming
