论文摘要
在Skip-Stop服务下运行的过境车辆仅访问沿着走廊的一部分停靠站。这是一种通常用于提高车辆速度并减少顾客旅行时间的策略。本文开发了一个连续的近似模型，以最佳设计Skip-Stop Service的精选形式，称为AB-Type服务。该模型解释了空间的需求模式。开发了一种有效的启发式方法来获得解决方案。对于各种数值示例，这些事实证明是几乎最佳的。结果还表明，在各种情况下，最佳的AB型设计优于优化的全站式服务。当旅行需求较高时，AB型服务被认为特别具有竞争力，旅行起源是沿着走廊分布不均的，并且顾客的时间价值相对较高。在这些情况下，发现AB型服务可将系统成本降低多达8％。
Transit vehicles operating under skip-stop service visit only a subset of the stops residing along a corridor. It is a strategy commonly used to increase vehicle speeds and reduce patron travel times. The present paper develops a continuous approximation model to optimally design a select form of skip-stop service, termed AB-type service. The model accounts for spatially-heterogeneous demand patterns. An efficient heuristic is developed to obtain solutions. These are shown to be near-optimal for a variety of numerical examples. Results also indicate that optimal AB-type designs outperform optimized all-stop service in a variety of cases. The AB-type service is found to be especially competitive when travel demands are high, trip origins are unevenly distributed along a corridor, and patrons have relatively high values of time. In these cases, AB-type service is found to reduce system costs by as much as 8%.
