Welcome to the website of the Urban Transportation & Behavior Research Group. We are based in the Department of Urban Planning and Policy at the University of Illinois at Chicago. The group is led by Dr. Nebiyou Tilahun. We are interested in researching issues surrounding travel behavior, the built environment and transportation systems, as well as the social and economic outcomes related to transportation. Our group is currently working on several projects in collaboration with colleagues at UIC and other institutions. We just released the Metropolitan Chicago Accessibility Explorer in February 2015. We are working on issues at the intersection of social exclusion and transport. Along with colleagues, we also organized and held the 2014 NSF sponsored Big Data and Urban Informatics workshop. Please browse through the site to see what we are working on.
