National Access Evaluation Pooled Fund - Phase III

The National Access Evaluation project has two main objectives. The first is to calculate national Census block-level Access datasets that can be used by partners in state and local transportation system evaluation, performance management, planning, and research efforts. The second is to add value to these datasets through research into questions of interest to Minnesota Department of Transportation (MnDOT) and the pooled fund Technical Advisory Panel (TAP), including research into the variability and change in access, as well as exploring access data in combination with other datasets. Access conditions will be described for 2025, 2026, 2027, 2028, and 2029. Accessibility evaluation has applications in a variety of areas: Strengthening Cost-Benefit Analysis - Understanding the impacts of transportation investments requires quantification of benefits. These benefits include economic opportunities, such as increased access to jobs, healthcare facilities, recreational activities, commercial activity, or other ways to participate fully in the economy. Access measures these opportunities in a way that can be applied in the context of a given project, or used to prioritize among transportation investments based on the expected benefits to different groups. Transportation and Land Use Research - Access calculations can provide a valuable data source for transportation and land use research. Researchers have employed access in models of mode choice and other aspects of travel behavior, linked access to residential property values, and used access to explore the spatial relationship between jobs and worker locations. Study partners can share the datasets produced by this study with consultants and researchers as a component of contracted projects. Performance Management [AD1] - By tracking access over time, transportation agencies at all levels of government can better understand how well their transportation networks support the goal of providing opportunity. Access evaluation can be applied to federal, state, and local performance goals. The reports produced by this study will track access performance each year, and over time as the study progresses. Study partners can share the datasets produced by this study without restriction, including (for example) with municipal and county transportation departments.
