【摘要】：針對過飽和信號交叉口車輛高能耗問題,以信號交叉口整個過飽和交通狀態(tài)持續(xù)時間作為研究時段,利用定數理論分析車輛排隊長度、停車次數和通行時間,確定車輛在信號交叉口的減速、怠速、加速和勻速行駛時間,進一步依據車輛在不同行駛狀態(tài)下的能源消耗率,建立了過飽和交叉口所有車輛第1次停車至通過停車線的平均能耗模型.為了驗證模型的準確性,以某個兩相位過飽和交叉口為例,對不同交通流量下的車輛能耗進行計算,并將計算結果與VISSIM仿真結果對比分析,結果表明,本文模型對過飽和信號交叉口的車輛能耗分析具有一定的合理性.同時,依據此模型分析了信號配時對過飽和交叉口車輛能耗的影響,說明了優(yōu)化配時參數對于過飽和交叉口車輛節(jié)能具有重要意義.
[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.
