摘　　要：本文在自动驾驶环境下,考虑交通网络中自动驾驶车辆(autonomous vehicles,AVs)的载人和空载状态在路段上相互影响,研究AVs路径选择和停车选择的组合均衡问题。首先,提出自动驾驶环境下考虑停车需求的交通均衡条件,建立网络均衡模型,证明模型的等价性以及解的唯一性;其次,采用网络变换法,将原问题变换为经典的用户均衡问题,使用相继平均法求解模型;最后,通过算例分析停车场费用对均衡的影响。结果表明:随着中心停车场费用的降低,个人总出行成本总体呈下降趋势,且局部路段流量变化幅度大;当中心停车场费用在一定范围内降低时,该停车场的需求量显著上升,其余停车场需求量总体上均有不同程度的下降;当中心停车场费用超出这个范围时,停车费的降低不影响停车选择结果。We considered the interaction between the human-occupied state and the empty state of autonomous vehicles(AVs)in the traffic network,and studied the combined equilibrium problem of AVs route choice and parking choice.Firstly,we proposed traffic equilibrium conditions considering parking demand in the autonomous driving environment,developed a network equilibrium programming model,and proved the equivalence of the model and the uniqueness of the solution.Then,the network transformation method was used to solve the model and the original problem was transformed into a simple user equilibrium problem,then the method of successive average was used to solve the model.Finally,the influence of parking cost on equilibrium was analyzed by an example.The results show that with the cost of the central parking lot decreases,the total personal travel cost decreases and the flows of some roads vary greatly.When the central parking fee decreases within a certain range,the parking demand increases significantly and the demand of other parking lots decreases to different extent on the whole.When the central parking fee exceeds this range,the decrease of parking fee does not affect the parking choice result.
