Trajectory Optimization for Connected Automated Vehicles Borrowing Urban Dedicated Bus Lane
摘要
Abstract
Connected and automated vehicles(CAV)can reduce the mutual interference with human driving vehi-cles(HDV),thereby enhancing the utilization efficiency of bus lanes,which is one of the important ways to improve the operation efficiency of CAV in the current mixed traffic flow environment.The trajectory optimization model of CAV utilizing bus lanes is proposed,taking into account the constraints of bus lane trajectory,the physical character-istics of the bus lane,and the traffic signal timing scheme.This model incorporates the overtaking behavior of CAVs at harbor bus stops.The model is decomposed into sub-models and meshed in time and space to elucidate the specif-ic process of model solution.The solution method is established based on a greedy algorithm-like algorithm,and the model is solved using MATLAB and yalmip solving tools.To illustrate the efficacy of the proposed model,numeri-cal simulations are conducted for the bus lane on Moganshan Road in Hangzhouas a case study.These simulations analyzed the impact of various factors,including harbor-style bus stop,bus stop time,and traffic signal timing pa-rameters on the model results,and further verified the effectiveness of the model.The results show that the bus stop time will significantly affect the CAV travel speed,and with the increase of bus stopping time,the CAV travel speed will increase first and then decrease.The results show that a collaborative optimization of bus stop time and traffic signal timing can enhance the operational efficiency of CAV.Furthermore,the presence of harbor-style bus stops has been found to augment the CAV operation speed by 10%when compared to the absence of such infrastructure.关键词
