公交优先信号交叉口延误计算与配时优化方法

设置公交优先感应信号控制可减少公交车辆在信号交叉口的延误．其最终目的是减少乘客的延误．分析了公交优先感应信号控制交叉口车辆延误的计算方法．探讨了公交优先感应信号控制以车总延误最小为配时优化目标的传统方法的不足，提出了以交叉口减少的人总延误最大为优化目标，以保障交叉口其余相位车辆能正常通行为约束条件的公交优先感应信号控制配时优化方法，其目的是在保障交叉口交通顺畅的前提下体现公交优先，并进行了实例应用分析．

Study of Vehicle Delay Calculation and Optimal Signal-planning Method for Intersections with Induced Signal Based on Bus Priority

The purpose of installing induction signal based on bus priority is to reduce the delay of buses and passengers in a signalized intersection. The delay calculation method of induction signal control based on bus priority is analyzed, the defect of the traditional induction signal control method based on bus priority with total vehicle delay minimum is discussed. A new induction signal control method based on bus priority with total passengers delay minimum and other phase vehicles passing intersection normally for restraint condition is suggested, and an application example is analyzed also. The purpose of this signal-planning method is to provide priority for buses and is to reduce the delay of buses on the premise of ensuring smooth traffic.
