Project Summary:

This project has two main objectives. First, it is creating 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 is producing and publishing a series of annual reports describing accessibility to jobs by driving and by transit in metropolitan areas across America.

  • Accessibility Dataset
    This project is creating a national Census-block level dataset describing accessibility to jobs from locations across the country, updated annually. Accessibility calculations rely on detailed travel-time calculations for both driving and transit, which are implemented using commercially available, GPS-based speed measurements and published transit schedules. Each Access Across America partner has direct digital access to the accessibility datasets covering the jurisdictions of all partners. The data is formatted such that the dataset can be easily accessed using popular software available on office computers.
  • Annual Report
    The annual Access Across America report provides summaries of the detailed accessibility datasets for the 50 largest metropolitan areas across America. This report is provided to national and local media outlets and supported by publicity and communications efforts. Partners are recognized in the report for their sponsorship and support.
