世界各地普遍存在机场和行动不便人士提供的拼车服务。与传统公共交通运营商不同，拼车运营商保持灵活的路线和时间表，用于提供门到门服务。这些路线和时间表通常是通过使用对未来旅行时间的完美预见的假设来创建的。然而，在实践中，车辆可能会遇到交通拥堵、因道路施工或事故而延误，甚至抛锚。因此，当假设条件完美时，路线和时刻表可能会遵守规划中的服务质量约束，但在操作上它们常常违反这些约束。本文研究了在确定性旅行时间假设下创建的路线和时刻表的有效性。本文评估了迫使时间表包含过多冗余的实际解决方案。最后，本文提出并评估了一种在实际操作中使用的追索方案，即为可能迟到的乘客分配出租车。该评估是在弗吉尼亚州里士满的真实案例研究中完成的。
Ridesharing services commonly offered at airports and to mobility-impaired persons exist worldwide. Unlike operators in conventional public transit, ridesharing operators maintain flexible routes and schedules that are used in providing door-to-door service. These routes and schedules are typically created by using the assumption of perfect foresight about future travel times. In practice, however, vehicles may encounter traffic congestion, be delayed because of road work or an accident, or even break down. Thus, the routes and schedules may adhere to quality-of-service constraints in planning when perfect conditions are assumed, but operationally they often violate such constraints. This paper investigates the effectiveness of routes and schedules created under a deterministic travel time assumption. The paper evaluates practical solutions that force the schedules to include excess slack. Finally, the paper proposes and assesses a recourse option for use in actual operations of assigning to taxis those passengers who are likely to be picked up late. The evaluation was completed on a real-world case study in Richmond, Virginia.
