Synthesis of Information Related to Transit Practices. Topic SA-52. Assessing Equity and Identifying Impacts Associated with Bus Network Redesigns

Total and per-capita public transit ridership in the US have been in decline after a recent peak in the mid-2010s. The causes of this decline are numerous: relatively low gas prices, easily available automobile loans, the advent of ride hailing companies, urban forms hostile to walking and bicycling, and job growth beyond the jurisdiction of transit agencies, among others. Highlighting public transit’s susceptibility to external factors, the worldwide COVID-19 outbreak is pushing transit ridership further downward. Such widespread and rapid ridership changes require creative solutions and direct action--notwithstanding global public health crises, and anticipating an eventual return to normalcy, individual transit agencies can make operational decisions to encourage ridership. Agencies across the country are realizing that a frequent bus network can support sustained ridership growth. Many agencies are undertaking “bus network redesigns” to focus resources in a manner that increases ridership and improves efficiency.  Relying on the fact that bus routes  can be shifted with relative ease and frequencies ramped up as needed, these efforts reallocate service from more peripheral areas to others where land use and demographic fundamentals indicate high ridership potential. Using redesigns and related changes, locations as diverse as Phoenix, Houston, Seattle, and Austin have recently seen ridership increases in the midst of national declines. The common denominator in each of these areas is the understanding that public transit level of service matters even in the face of broader macroeconomic trends that do not favor transit ridership. However, despite obvious success in growing ridership, the equity and justice impacts of bus network redesigns are poorly understood and often contentious. A recent research effort focused on bus network redesigns, TCRP Synthesis 140, addressed a host of general issues related to redesigns, but did not engage deeply with equity-related questions. Instead, the report limited its equity investigation to the basic federally required processes, noting that Title VI analyses were the favored method for assessing impacts on people of color and low-income people. But, Title VI analyses often rely on census data to understand who would be affected by a service change, even though ridership data often show different results. Title VI analyses can also be conducted in many different ways, including via methods that may minimize evidence of negative outcomes for Title VI protected populations. There is little standardization across transit agencies when evaluating the impacts of their network redesigns. This TCRP synthesis will document the current practice of how transit agencies are assessing and addressing the equity impacts of bus network redesigns, including and beyond Title VI analyses.  Information gathered will include an inventory of all available equity-related documents produced by agencies that have undertaken bus network redesigns in the US. Information will be gathered by a literature review, a survey on a broad range of North American transit agencies and a minimum of 5 case examples that will gather information on the state-of-the-practice, emphasizing lessons learned, challenges and successes. The needs for future research should also be discussed. The products of the synthesis will serve as a resource to inform transit agencies considering bus network redesigns of strategies to understand the true impacts of major service changes on the communities that they serve.
