What is Reducing Conflict: Choosing an Auto Accessibility Catchment Radius Explicitly to Serve Low-Income Populations about?

An implicit choice in the project prioritization process is the extent to which candidate projects should be evaluated with respect to their ability to serve low-income populations. Thus, a conflict can arise regarding the percentage of a project's evaluation that should be earmarked for these groups. As jobs-based accessibility is also a component of project prioritization, this paper puts forth a method for reducing this conflict: judicious selection of the catchment radius. Mathematically, this radius (the spatial extent of a project's impacts on jobs access) substantially affects a project's forecast improvement on accessibility. This paper describes how to choose this radius such that the net accessibility benefit of a candidate project when all populations and all jobs are considered is similar to the net accessibility benefit when only low-income populations and associated employment are considered. Findings from five candidate projects studied indicated that the catchment radius may affect project evaluation when total and low-income populations are considered based on three proposed measures of consistency. With the first consistency measure (differences in accessibility s
