论文摘要
共享经济和智能手机的出现使需求运输服务成为可能，从而创造了更多的机会，但对城市流动性也更加复杂。提供这些服务的公司由于其基于互联网的本性而称为运输网络公司（TNC）。尽管乘坐乘车是TNC提供的最臭名昭著的服务，但在更换其他运输模式的同时，或者当大量闲置车辆在乘客巡航时，其操作在多大程度上可以干扰在多大程度上。我们使用来自中国大型的出租车跳闸数据和具有基于旅行的MFD模型的基于代理的模拟来分析TNC的效率，以确定速度。我们调查了扩大TNC的车队规模的影响，乘客倾向于分享游乐设施的倾向以及减轻城市拥堵的战略。我们表明，TNC和社会之间缺乏目标的协调可以创造37％的旅行时间和大量交通拥堵。此外，允许共同的游乐设施无法减少由于行进较高的空旷公里的较高的总距离。优雅的停车管理策略可以防止闲置的车辆在没有指定的乘客的情况下巡航，而没有协调的影响降至7％。
The advent of shared-economy and smartphones made on-demand transportation services possible, which created additional opportunities, but also more complexity to urban mobility. Companies that offer these services are called Transportation Network Companies (TNCs) due to their internet-based nature. Although ride-sourcing is the most notorious service TNCs provide, little is known about to what degree its operations can interfere in traffic conditions, while replacing other transportation modes, or when a large number of idle vehicles is cruising for passengers. We experimentally analyze the efficiency of TNCs using taxi trip data from a Chinese megacity and a agent-based simulation with a trip-based MFD model for determining the speed. We investigate the effect of expanding fleet sizes for TNCs, passengers' inclination towards sharing rides, and strategies to alleviate urban congestion. We show that the lack of coordination of objectives between TNCs and society can create 37% longer travel times and significant congestion. Moreover, allowing shared rides is not capable of decreasing total distance traveled due to higher empty kilometers traveled. Elegant parking management strategies can prevent idle vehicles from cruising without assigned passengers and lower to 7% the impacts of the absence of coordination.
