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.

This special topic report examines the prevalence and characteristics of co-occurring substance abuse and mental health problems among juvenile detainees in Maricopa County. The findings come from the Co-occurring Disorder Addendum used during 2007. The findings reveal that almost 30 percent of juvenile detainees were at risk for a co-occurring disorder, and face significantly greater difficulties across a number of critical factors, including incarceration, homelessness, and victimization.
