Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

As part of the Bureau of Justice Assistance’s Smart Policing Initiative, the Glendale Police Department and the Center for Violence Prevention and Community Safety at Arizona State University found that convenience stores -- particularly Circle K's -- disproportionately contributed to crime and disorder in the city of Glendale. The Center reached out to other law enforcement agencies in the Phoenix metropolitan area, and in June 2011, they authored a report based on 2010 data from four cities: Glendale, Mesa, Phoenix, and Tempe. The 2010 report revealed that, when compared to other convenience stores Circle K’s, were disproportionately responsible for crime and disorder, regardless of their neighborhood or city.
