论文摘要
本文提出了一种方法来分析多模式公共交通（PT）的影响，结合了传统的固定式跑车运输和需求响应性运输（DRT）对运输可及性分布的平等性。我们基于一般过境饲料规范（GTFS）数据，在NEO4J中构建了多模式PT的图模型，分析（使用连续近似）对DRT进行建模。我们使用可访问性措施在任何位置量化了服务质量，表明可以轻松地达到其他位置或机会。我们量化可访问性分布的不平等。我们指出了分配DRT机队以最大程度地减少不平等并显示其NP完整性的问题。我们在法国小镇Royan的运输网络上展示了我们的方法。
This paper proposes an approach to analyze the impact of multimodal Public Transit (PT), combining conventional fixed-route transit and Demand-Responsive Transit (DRT), on equality in transport accessibility distribution. We construct a graph model of multimodal PT in Neo4j, based on General Transit Feed Specification (GTFS) data, modeling DRT analytically (using continuous approximation). We quantify service quality on any location using an accessibility measure, indicating how easily other places or opportunities can be reached. We quantify inequality of accessibility distribution. We state the problem of allocating a DRT fleet to minimize inequality and show its NP-completeness. We showcase our approach on the transportation network of the French town of Royan.
