建立了一个网络模型来描述空置和被占用的出租车如何在道路网络中巡航以寻找客户和提供交通服务。该模型可以确定多个均衡的系统性能指标，如给定路网的空置出租车流量和出租车利用率以及客户起点-目的地需求模式。明确考虑了出租车车队规模和不确定性对系统性能的影响。该模型对出租车服务均衡的本质提供了一些有趣的见解，并为决策提供了一些与政策相关的结果。研究结果显示，的士的平均使用率随着的士营运数目的增加而大幅下降，而的士使用率越高，乘客的平均轮候时间便越长。
A network model is developed to describe how vacant and occupied taxis will cruise in a road network to search for customers and provide transportation services. The model can determine a number of system performance measures at equilibrium, such as vacant taxi movements and taxi utilization for a given road network and the customer origin–destination demand pattern. The effects of the taxi fleet size and the uncertainty on the system performances are explicitly taken into account. The model offers some interesting insights into the nature of the equilibrium of taxi services, and offers some policy-relevant results for decision making. These include the findings that the average taxi utilization decreases sharply with the number of taxis operating, and that the higher the taxi utilization, the larger the average customer waiting time.
