论文摘要
本文提出了一种交互式浴缸模型，用于描述包括非共享出租车和乘车汽车在内的乘车车辆的交通动态。假定一个拥有未分化的街道和仅由乘车服务服务的城市，可以促进建模，隔离拥塞的贡献并因此制定控制策略。所提出的模型仅具有网络总车道长度，需求中的通用和旅行距离分布的输入信息。但是，该模型的输出不仅捕获了车辆的交通动态，而且还捕获了乘车服务中乘客的动态状态，以总数，剩余的旅行距离以及任何系统时间的无与伦比请求的队列。可以利用有用的系统指标来使用当局来监视，预测和控制流量以及TNC，以确定车队尺寸，调度车辆并衡量服务生产率。为了插图，我们提出了一项强大的控制规则，以有效地管理流量并避免僵局，还提出了时间变化的乘车大小，以消除无与伦比的请求的队列。数值示例证明了所提出的模型以及控制和操作策略的有效性。
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.
