Piloting On-Demand Multimodal Transit in Atlanta

How the system works

Mobility Patterns in Atlanta

This project will pilot an On-Demand Multimodal Public Transit System (ODMTS) in Atlanta to improve accessibility to jobs, healthcare, and healthy food. ODMTSs are a new generation of public transit systems that improve mobility for all population segments, and are convenient, economically sustainable, and environmental friendly. An ODMTS combines on-demand vehicles to serve the first/last miles, with high-frequency rail or bus routes to transport commuters on dense and congested corridors. They promise to transform public transit into a flexible, scalable, and affordable system that meets the needs of all residents regardless of where they live in the service area.As such, ODTMSs are particularly suited to fill in service gaps left by a fixed bus route.

This project takes the next critical step to demonstrate these potential benefits in the field, and, in particular, for communities that have been significantly disadvantaged in the past. It will take place in Atlanta, which presents a challenging environment for mobility: Atlanta is the 11th most congested city in the country and MARTA, its public transit agency, only serves about 10% of the commuting share. The pilot project will test the efficiency of an ODTMS and provide information on whether a large-scale version would work across MARTA’s service area as the agency is undertaking a comprehensive redesign of its bus network. The service will be tested in areas where there is a need for greater transit accessibility in DeKalb, Clayton, and Fulton counties and the City of Atlanta. It will connect to nearby fixed bus route transfer hubs, such as rail stations and Park & Rides, and use MARTA’s current fare of $2.50 with transfers included. 

To implement this pilot, the project brings together a truly multi-disciplinary team composed of MARTA, the 8th largest transit agency in the US, the Altanta Bicycle Coalition, a transit advocacy group, and researchers at Georgia Teach who have pioneered the concept of ODMTS and have significant experience in all aspects of the project. The pilot will be operated by MARTA using the software infrastructure provided by Georgia Tech. The community engagement will be driven by the researchers in symbiosis with MARTA’s Office of Stakeholder and Public Engagement, using advice from the Altanta Bicycle Coalition.

The transition from the ODMTS concept to a field pilot raises significant community challenges. The service should be accessible to all population segments and bridge the digital divide that exists for multiple population segments. This requires flexible payment options; flexible communication methods; and (3) multi-language mobile applications. The pilot cannot assume that riders will have credit cards, access to a cellular plan for a smart phone, or speak English. To evaluate success, the project will provide a counterfactual study comparing the baseline performance of the existing system and the proposed pilot, based on the following metrics: transit ridership, wait and in-vehicle travel time, accessibility, and  satisfaction. These metrics quantify accessibility, performance, and appeal of the ODMTS, and will provide invaluable information for future transit systems.
