Abstract

This paper addresses an existing methodological and empirical gap by presenting a framework for conducting a regional cumulative accessibility analysis of a transit network with an on-demand component and demonstrating its application to the context of a mid-sized Canadian city. We rely on the concept of accessibility as a performance metric and propose a methodological approach for inferring inputs for accessibility calculations from actual on-demand operations in Edmonton, Canada, to develop the tool for the accessibility assessment of a transit network with an on-demand component. Our empirical findings show that on-demand zones that were introduced with a redesigned bus network saw the largest gains in transit accessibility, and we identified that excluding on-demand transit from accessibility analysis underestimates the systemic effect of the bus network redesign. While the use of the accessibility framework for the assessment of a transit system with an on-demand component offers a meaningful and comprehensive measure of the success both for the planning purposes at the stage of design and for the post-implementation evaluation of either incremental or systemic changes, on-demand service standards must be developed to ensure consistent service provision of on-demand services throughout the day. On the other hand, informed by the findings of our study and publicly available information about the operational costs of service provision we identified that on-demand service provides operational savings over fixed routes if ridership in the area is less or equal to eight passengers an hour.
计算:按需交通可达性评估的方法框架
本文提出了一个框架,对一个按需组成的交通网络进行区域累积可达性分析,并展示了其在加拿大一个中型城市的应用,从而解决了现有方法和经验上的差距。我们将可达性概念作为一种绩效指标,并提出了一种方法方法,用于推断加拿大埃德蒙顿实际按需运营的可达性计算输入,以开发具有按需组件的交通网络可达性评估工具。我们的实证研究结果表明,引入重新设计的公交网络的按需区域在公交可达性方面获得了最大的收益,并且我们发现,将按需公交排除在可达性分析之外低估了公交网络重新设计的系统效应。虽然使用可达性框架来评估具有按需组件的交通系统,为设计阶段的规划目的和对增量或系统变化的实施后评估提供了一个有意义和全面的成功衡量标准,但必须制定按需服务标准,以确保全天按需服务的一致提供。另一方面,根据我们的研究结果和有关服务提供的运营成本的公开信息,我们确定,如果该地区的乘客少于或等于每小时8名乘客,按需服务将比固定路线节省运营成本。
