【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,建立了过饱和交叉口所有车辆第1次停车至通过停车线的平均能耗模型.为了验证模型的准确性,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,本文模型对过饱和信号交叉口的车辆能耗分析具有一定的合理性.同时,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]:In order to solve the problem of high energy consumption in over-saturated signalized intersections, the whole oversaturated traffic duration at signalized intersections is taken as the study period, and the queue length, parking times and traffic time of vehicles are analyzed by using the theory of fixed number. Determine the deceleration, idling, acceleration and uniform travel time of vehicles at signalized intersections, and further base on the energy consumption rates of vehicles in different driving states, In order to verify the accuracy of the model, an average energy consumption model for all vehicles at a supersaturated intersection is established. In order to verify the accuracy of the model, the vehicle energy consumption at a two-phase supersaturated intersection is calculated under different traffic flows. The results are compared with the results of VISSIM simulation. The results show that the model is reasonable for the analysis of vehicle energy consumption at supersaturated signalized intersections. According to this model, the influence of signal timing on vehicle energy consumption at supersaturated intersection is analyzed, and the importance of optimizing timing parameters for vehicle energy saving in supersaturated intersection is explained.
