Sadegh Sabouri is a doctoral student in the department of City and Metropolitan Planning and research assistant at the Metropolitan Research Center. He has traveled to many cities and countries around the world, from crowded Shanghai and Beijing in China to Moscow to smaller cities like Minsk and Vilnius in Belarus and Lithuania, respectively. He has found each place has its merits and demerits and he was always drawn to solving city problems like traffic and pollution. This ambition led him to pursue bachelor’s and master’s degrees from the University of Tehran in urban planning. During that time, he contributed to projects at Iran’s Ministry of Road and Urban Development and at private engineering firms. His current research interests are integrating land-use and transportation planning, mobility systems planning, and technology’s impact on urban forms and developments. Now at the University of Utah, he is continuing his study of Transit Oriented Development (TOD), which was the topic of his master’s thesis. More specifically, he wants to know why after more than thirty years since the introduction of TOD, this approach has failed to completely solve urban sprawl as one of the biggest problems of our cities and metropolises. Despite the numerous benefits, why is it that in 2014 more than 80% of U.S. citizens still prefer to live in single-family detached houses? And why don’t they want to live in mixed-use areas with proper access to public transport? He hopes his research will identify the deficiencies and shortcomings of TODs, and ways in which planners might address those challenges.
