National Accessibility Evaluation

This project has two main objectives. First, it will create a new, national Census block-level accessibility dataset that can be used by partners in local transportation system evaluation, performance management, planning, and research efforts. Second, it will produce and publish a series of annual reports describing accessibility to jobs by driving and by transit in metropolitan areas across America. This project will create a national Census-block level dataset describing accessibility to jobs from locations across the county, updated annually. Accessibility calculations will rely on detailed travel time calculations for both driving and transit, which will be implemented using commercially-available, global positioning system (GPS) based speed measurements and published transit schedules. Each Access Across America partner will have direct digital access to the accessibility datasets covering the jurisdictions of all partners. The annual Access Across America report will provide summaries of the detailed accessibility datasets for the 50 largest metropolitan areas across America. This report will be released to national and local media outlets and supported by publicity and communications efforts. Partners will be recognized in the report for their sponsorship and support.
