Developing Data, Models, and Tools to Enhance Transportation Equity

Because these data are so essential to shaping our transportation system, it is critical that hard-to-reach populations—such as low-income, minority, and transit-dependent people—have their travel behavior accurately reflected. The limited survey coverage may lead to inaccurate estimation of their transportation access and behavior, impede policy changes related to transportation...

The preference for these separated facilities appears to be greater amongst cyclists who ride primarily for recreation (as opposed to for transportation) and among those who c...
