The Arizona State Rail Plan (SRP) is the first comprehensive assessment of the stateís rail needs and was initiated in response to the increasing involvement by ADOT in freight and passenger rail issues. The SRP serves to identify the current rail system, to determine infrastructure needs, and to have rail projects included in the state's long-range planning processes to improve regional and statewide safety mobility. The principle purpose is to convey the magnitude of the rail needs in the state and set forth a policy framework through which strategic actions can be taken to realize the full potential of passenger and freight rail transportation.

In 2006, the Bureau of Justice Statistics awarded a State Justice Statistics grant to the Arizona Criminal Justice Commission’s Statistical Analysis Center to conduct research on homicide in Arizona. The Center, with assistance from local law enforcement officials, and researchers from the School of Criminology and Criminal Justice at Arizona State University, collected homicide data from the following sources: Supplemental Homicide Reports, law enforcement homicide case files, and autopsy reports. The purpose of this report is to provide a general description of the scope and nature of the homicide problem in Arizona. Specifically, this report examines the general characteristics of victims and offenders, the circumstances surrounding homicide incidents, temporal patterns when homicides occur, and the geographic characteristics where homicides took place.

This inventory includes emissions of coarse particulate matter <10 µm in diameter (PM10), fine particulate matter < 2.5 µm (PM2.5), nitrogen oxides, sulfur oxides, and ammonia. Emissions are calculated for both Maricopa County and the PM10 nonattaiment area. Annual totals as well as typical daily emissions are provided for all source categories.
