This paper reports on the results of the six-month pilot MARTA Reach, which aimed to demonstrate the potential value of On-Demand Multimodal Transit Systems (ODMTS) in the city of Atlanta, Georgia. ODMTS take a transit-centric view by integrating on-demand services and traditional fixed routes in order to address the first/last mile problem. ODMTS combine fixed routes and on-demand shuttle services by design (not as an after-thought) into a transit system that offers a door-to-door multimodal service with fully integrated operations and fare structure. The paper fills a knowledge gap, i.e., the understanding of the impact, benefits, and challenges of deploying an ODMTS in a city as complex as Atlanta, Georgia. The pilot was deployed in four different zones with limited transit options, and used on-demand shuttles integrated with the overall transit system to address the first/last mile problem. The paper describes the design and operations of the pilot, and presents the results in terms of ridership, quality of service, trip purposes, alternative modes of transportation, multimodal nature of trips, challenges encountered, and cost estimates. The main findings of the pilot are that Reach offered a highly valued service that performed a large number of trips that would have otherwise been served by ride-hailing companies, taxis, or personal cars. Moreover, the wide majority of Reach trips were multimodal, with connections to rail being most prominent

翻译：本文报告了为期六个月的MARTA Reach试点项目的结果，该项目旨在展示按需多模式公交系统（ODMTS）在佐治亚州亚特兰大市的潜在价值。ODMTS以公交为核心视角，通过整合按需服务与传统固定线路来解决"第一/最后一公里"问题。ODMTS将固定线路与按需班车服务进行系统性整合（而非事后补充），构建了提供门到门多模式服务且运营与票价体系完全一体化的公交系统。本文填补了关于在亚特兰大（佐治亚州）这类复杂城市部署ODMTS时的影响、效益及挑战等认知空白。该试点在四个公交选择有限的区域开展，采用与整体公交系统整合的按需班车来解决"第一/最后一公里"问题。本文阐述了试点的设计与运营，并呈现了乘客量、服务质量、出行目的、替代出行方式、出行多模式特征、面临挑战及成本估算等方面的结果。试点的主要发现是：Reach提供了一项高价值服务，完成了大量原本由网约车、出租车或私家车承担的出行。此外，绝大多数Reach出行具有多模式特征，其中与铁路的衔接最为显著。
