摘    要:
针对过饱和信号交叉口车辆高能耗问题, 以信号交叉口整个过饱和交通状态持续时间作为研究时段, 利用定数理论分析车辆排队长度、停车次数和通行时间, 确定车辆在信号交叉口的减速、怠速、加速和匀速行驶时间, 进一步依据车辆在不同行驶状态下的能源消耗率, , 以某个两相位过饱和交叉口为例, 对不同交通流量下的车辆能耗进行计算, 并将计算结果与VISSIM仿真结果对比分析, 结果表明, , 依据此模型分析了信号配时对过饱和交叉口车辆能耗的影响, 说明了优化配时参数对于过饱和交叉口车辆节能具有重要意义.

Abstract:
Aiming at the problem of high energy consumption of vehicles at oversaturated signalized intersection, taking oversaturated traffic state of signalized intersection as the research period, the queue length, the number of stops and the time of pass through are analyzed by using the fixed number theory. It is determined that the vehicle travel time of deceleration, idle speed, acceleration and constant speed at signalized intersections. According to the vehicle energy consumption rate under different working conditions, the average energy consumption model for all vehicles at oversaturated intersec
