为了评估网联自动驾驶汽车(CAV)的自主停车行为对交通系统效率的影响,建立了CAV通勤流、人工驾驶汽车(HDV)通勤流、CAV自主停车流3类交通流混行下的交通均衡配流模型.通过引入CAV停车需求内生变量,考虑CAV对路段通行能力的提升效应,从而定量描述CAV停车需求分布以及3类交通流在路段上混行的拥挤效应.分别采用用户均衡、随机用户均衡原则描述CAV、HDV出行者的路径选择行为,采用Logit离散选择模型描述自主停车CAV的停车场选择行为,由此建立多用户混合交通均衡条件以及等价的变分不等式(VI)模型.由于模型中CAV自主停车需求为未知的内生变量,提出一种改进的相继加权平均法求解该模型.最后,通过算例验证了混合交通均衡配流模型及求解算法的有效性.
Mixed traffic equilibrium assignment model considering automated parking behaviors of CAV
In order to evaluate the impacts of automated parking behaviors of connected and autonomous vehi-cle(CAV)on the traffic system efficiency,a traffic equilibrium assignment model is established in the context of the mixed traffic flows consisting of the commuter flows of CAV and human-driven vehicle(HDV)and au-tomated parking flows of CAV.By introducing the endogenous variables of CAV parking demands and consid-ering the improvement effect of CAV on road capacity,the demand distribution of CAV parking flows and the congestion effects of three types of mixed traffic flows on a road section are described quantitatively.The user equilibrium(UE)and stochastic user equilibrium(SUE)principles are adopted to describe the route choice behaviors of CAV and HDV travelers,respectively.Meanwhile,the Logit-based discrete choice model is adopted to describe the parking facility choice behaviors of the parking CAV.Based on them,the multi-class mixed traffic equilibrium conditions and the equivalent variational inequality(VI)model are established.Since the CAV parking demands are unknown endogenous variables in the model,the modified method of suc-cessive weighted averaging(MSWA)is developed to solve the model.Finally,numerical examples are pro-vided to validate the effectiveness of the mixed traffic equilibrium assignment model and its solution algorithm.
