junfeng_jiao2Abstract: The term “transit desert” is a new concept that looks at the gap between level of transit service (supply) and needs of a particular population (demand). These populations are often referred to as “transit dependent,” people that are too young, too old, or too poor or who are physically unable to drive. “Transit deserts” in this case are defined as areas that lack adequate public transit service given areas containing populations that are deemed transit-dependent. This study aims to analyze and establish a clear method for calculating and quantifying gaps between transit demand and supply using Geographic Information Systems (GIS). The study looks at eight major U.S. cities: Charlotte, NC; Chicago, IL; Cincinnati, OH; Portland, OR, Austin, Dallas, Houston and San Antonio, TX. Transit deserts often occur in neighborhoods surrounding historic downtowns; however, exceptions occur in very isolated rural areas.

Biographical Summary: Junfeng Jiao is an Assistant Professor in the Community and Regional Planning Program and director of the Urban Information Lab in the School of Architecture at the University of Texas at Austin. He received his PhD in Urban Design and Planning from the University of Washington and three Masters in Transportation Engineering, Geographic Information System (GIS), and Architecture from the University of Washington, University of Twente and Wuhan University, respectively.

Dr. Jiao’s research investigates the application of GIS and information technology to understand people’s access to transportation infrastructures and the related health impact. He uses a variety of GIS and information technologies to examine people’s access to food, biking, and transit facilities and the related health outcomes. His efforts have been supported by various funding agencies (USDOT, RWJF, NIH etc.). He has published over 25 academic papers and book chapters in different peer reviewed journals.
