The goal of integrating accessibility into transportation planning is to ensure that congestion mitigation measures encourage transportation equity and urban space livability. Traditional methods of estimating travel time, travel time reliability, and trip length information to power accessibility measures have largely focused on modeling and/or estimation procedures, displaying a hypothetical universe of access — not where travel actually occurs. This research project will develop a suite of measures to assess accessibility, taking advantage of available crowdsourced origin-destination data to identify accessibility from real data rather than a modeled approach. The measures (e.g., travel time to/from destinations, trip length, access to jobs, etc.) will be estimated for cities of varying size and U.S. geographic distribution to inform congestion-mitigation decision-making based on actual travel behaviors. The results of this work will help transportation planners and policy makers understand locations where access is (or is not) adequately provided to identify appropriate and innovative solutions for shifting travel behavior to more sustainable approaches.
The 2021 Urban Mobility Report website will include the results of the accessibility analysis and new performance measures. In subsequent years, the methods will be honed with feedback from academic and practitioner peer review, after the release of the information on the UMR website, and with the availability of more data. NICR will be shown as a 2021 Urban Mobility Report sponsor on the UMR website. |
