High housing prices in areas close to ASU’s Tempe campus keep many students from living near the school. But that often means those students commute to the campus, where they’ve been hit with rising costs for parking. Various factors create this situation, explains civil engineer Steven Polzin, a research professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. The former the U.S. Department of Transportation senior advisor says one reason is the Phoenix area’s urban sprawl, which often results in low use of public transit and more automobile travel that leads to higher public parking costs.
