网约车服务城市的交通动力学与最优控制
Traffic dynamics and optimal control in a city served by ride-sourcing vehicles
摘要：
本文提出了一个交互式浴缸模型，用于描述非共享出租车和拼车车辆的交通动力学。假设一个城市的无差别的街道网络，仅由乘车外包服务，以促进建模，隔离的拥堵贡献，并相应地制定控制策略。所提出的模型是简约的，只有输入信息的总车道长度的网络，在流量的需求，和行程距离分布。然而，该模型的输出不仅捕获了车辆的交通动态，还捕获了拼车服务中乘客的动态状态，包括总数量、剩余行程距离以及任何系统时间的不匹配请求队列。可以利用有用的系统度量标准供当局监测、预测和控制交通，以及供跨国公司确定车队规模、调度车辆和衡量服务生产率。为了说明，我们提出了一个鲁棒控制规则，以有效地管理交通，避免交通堵塞，并提出了随时间变化的乘坐池大小，以消除队列不匹配的请求。数值算例验证了所提模型及控制策略和运行策略的有效性。
英文摘要：
This paper presents an interactive bathtub model for describing the traffic dynamics of ride-sourcing vehicles including non-shared taxis and ride-pooling cars. A city with a network of undifferentiated streets and solely served by ride-sourcing services is assumed to facilitate the modeling, isolate the congestion contribution, and accordingly develop control strategies. The proposed model is parsimonious with only input information of the total lane length of the network, the in-flux of demand, and the travel distance distributions. The output of the model, however, captures not only the traffic dynamics of vehicles but also the dynamic states of passengers in ride-pooling services in terms of the total number, the remaining travel distances, and the queue of unmatched requests at any system time. Useful system metrics can be exploited for use of the authorities to monitor, predict, and control the traffic, as well as for the TNCs to determine the fleet sizes, dispatch vehicles, and measure the service productivity. For illustration, we propose a robust control rule to manage the traffic efficiently and avoid gridlock, and also present time-varying ride-pooling sizes to eliminate the queue of unmatched requests. Numerical examples demonstrate the effectiveness of the proposed model and the control and operation strategies.
