Description
The Arizona Department of Transportation (ADOT) Roadway Departure Safety Implementation Plan (RDSIP) has identified tree removal as a feasible countermeasure to reduce roadway departure crash frequency or severity. Previous ADOT work has identified locations for tree removal, and activities to conduct this work are underway. To test the safety effectiveness of removing the trees, ADOT intends to conduct statistically rigorous before-after safety effectiveness analysis to estimate state-specific crash modification factors (CMFs).

Description
Windblown dust events occur in Arizona, and blowing dust has been considered a contributing factor to serious crashes on ... Arizona roadways.... [T]he Arizona Department of Transportation (ADOT) acquires information about predicted or in-progress dust events through National Weather Service forecasts and advisories and through field reports from motorists and ADOT personnel. ADOT then communicates this information to the public.... During this project, researchers developed a set of recommendations that ADOT can implement to identify the most effective means for acquiring data about windblown dust events, communicating ... to the public, and influencing driver behavior....--Page v.

Description
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.
