metro | cincinnati Diagram Map began in 2009 as an academic design project to develop an architectural master plan for a regional rapid transit system for the Greater Cincinnati and Northern Kentucky metropolitan area. Although periodic efforts have been made to introduce rail transit to the region, including the partial construction of a subway line in the 1920’s and the current efforts to re-introduce streetcar service to the downtown core, Greater Cincinnati remains one of the largest US urban areas without any form of rail-based public transit. This proposal is loosely based upon the 2002 Metro Moves light rail initiative developed by the Southwest Ohio Regional Transit Authority and the 2030 Regional Transportation Plan unanimously adopted in 2008 by the OKI Regional Council of Governments.

Issues regarding capital and operational funding, public transit policy, ridership projections, civil and structural engineering, and political feasibility were not included within the scope of the design project itself. However, these issues are touched upon in the background research and in the author’s commentary.

Since the conclusion of the academic aspect of the project in the spring of 2010, the focus of this site and its associated social media outlets have evolved. Aspects of the transit master plan have been periodically improved and clarified, while the blog portion of the site has become a platform for education, commentary, and advocacy regarding the future of public transit in Cincinnati and beyond.

Your comments, questions, and feedback are always appreciated.

The primary focus of the project concerns the physical design of a hypothetical transit system, with a particular emphasis on the following three aspects:

Routes, Transit Modes, and Station Locations
The 2002 Metro Moves plan envisioned a three-tier system comprised of streetcars, light rail, and commuter rail. Several of the proposed light rail corridors incorporate abandoned railroad rights-of-way and run on surface streets in the central business district. While this provided a cost-effective way to introduce rail transit to Cincinnati, it had a number of shortcomings that limited the system’s future capacity and public appeal. Using the OKI plan as a starting point, this project proposes a modified regional plan that better serves the long-term transit needs of the public.

Station Typologies
This project identifies typical transit station typologies (subway, elevated, surface, etc.) and establishes architectural design parameters to create a framework by which the design of these facilities can be further developed in the future.

Downtown Transit Hub
Finally, this project proposes a schematic design for the primary downtown transit hub, located at the site of the existing below-grade Fountain Square parking garage, which will provide the primary transfer point between most of the proposed transit lines.
