Abstract:

Aging public transit systems will require significant investment into state of good repair (SGR) over the coming decades, while at the same time many metropolitan areas in the United States seek to expand existing services and infrastructure. The prioritization of limited funding is a challenging process, particularly when choosing between new transit infrastructure and SGR for existing assets. Furthermore, this process rarely takes user benefits into consideration in a rigorous quantitative way. While asset management professionals have made significant progress in age-based and condition- based methodologies to prioritize transit asset replacement, it is more difficult to assess the impact of these SGR investments on users. This paper develops a new methodology to estimate user benefits across a metropolitan region resulting from transit SGR funding. The method builds on existing age-based models of asset failure and the San Francisco Bay Area’s regional activity-based travel model. The method is applied to the transit asset inventory of the entire Bay Area to compare two regional funding scenarios to a baseline scenario reflecting current funding levels. The results indicate that the benefits from regional funding for transit SGR in the Bay Area far exceed expenditures. Further research using this method could assist planners in determining the optimal level of funding for transit SGR and assist in prioritizing specific SGR projects in a consistent manner to expansion investments.
