Improving reliability in the Montreal transit system

公共交通服务可靠性是指公共交通系统遵守时间表和/或保持定期间隔和一致旅行时间的能力。 换句话说，可靠性可以定义为系统性能测量在一段时间内的变化。从理论上讲，在准确的时间表下，公交服务可靠性的提高应该会导致服务生产率的提高。在这个研究项目中，我们详细调查了蒙特利尔地区的一条高频公交线路，并在试验中介绍了提高沿着公交服务可靠性的各种方案。此外，本计画亦详细探讨数种评估公交信号优先作为提高服务可靠性之有效性的方法。

Transit service reliability is the ability of transit system to adhere to schedule and/or maintain regular headways and a consistent travel time. In other words, reliability can be defined as the variability in the system performance measure over a period of time. In theory, an increase in transit service reliability should lead to an increase in service productivity, given accurate schedules. In this research project we investigate in detail one of the high frequency bus lines in the Montreal region in a trial to introduce various scenarios for increasing transit service reliability along this route. In addition this project also investigates in detail several methodological approaches for evaluating effectiveness of transit signal priority as a method for increasing service reliability as well.
