摘　　要：共享自动驾驶电动汽车是未来城市道路智能交通的重要出行方式。传统的单一快车直达模式无法充分利用车辆,导致订单满足率和经济效益较低,因此本文提出在共享自动驾驶电动汽车动态运营决策问题中开放拼车模式并引入转运策略。该问题首先以时间、空间、电池量和载客量这4个维度的信息构建四维单商品流时空网络,然后通过弧的合并简化至三维单商品流时空网络。在此基础上,建立以运营利润最大化为目标的纯整数线性规划数学模型。最后采取滚动优化方法,设置多个前视时间窗匹配快车、拼车、转运等异质类服务,以GUROBI为优化引擎对前视期子问题进行快速求解,满足实际动态运营场景。算例结果表明:车队规模与出行需求量匹配时,在较为均匀与不均匀的两种需求分布情境下,拼车模式下引入转运策略使系统运营利润较单一快车直达模式分别提高11.60%和13.85%。Autonomous electric shared vehicle is an important intelligent mode for future urban transportation.The traditional single ride-hailing model fails to fully utilize vehicles,resulting in low order fulfillment rates and economic benefits.Therefore,this paper proposes a ride-splitting model and adopts relay strategies for the dynamic operational decision-making of autonomous electric shared vehicles system.The study first constructs a four-dimensional spatiotemporal network based on time,space,battery level,and passengers,which is then simplified to a three-dimensional network through arc merging.Based on this topological network,a pure integer linear programming model is developed to maximize operational profit.A rolling optimization method is introduced with multiple Forward-looking time windows matching heterogeneous services like single ride-hailing,ride-splitting,and relay service.Using GUROBI as the optimization engine,the subproblems for the Forward-looking period are solved quickly to meet practical dynamic operating scenario.A case study demonstrates that,under moderate travel demand,the introduction of ride-splitting and relay strategy increases operational profit by respectively 11.60%and 13.85%under the uniform and non-uniform demand distributions.
