Research Highlights

Developing Data, Models, and Tools to Enhance Transportation Equity

Amy Lubitow Julius McGee , Raoul Liévanos
Data from travel surveys are used to forecast demand, inform transportation investments, and craft urban policies. 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… Read More

Rapidly Expanding Mobile Apps for Crowd-sourcing Bike Data to New Cities

Sean Barbeau Nevine Georggi , Julie Bond
Cities such as San Francisco, Atlanta, and Portland are using novel methods of data collection to learn more about the use of their bicycle infrastructure. These data can help transportation planners better design or upgrade bicycle facilities. San Francisco created an open-source project, Cycle Tracks, a mobile app used to collect bike path data from bicyclists’ smartphones. These data then were used in the SF-CHAMP travel demand model to forecast how attractive Bike Facility A would be… Read More
