Description

A primary objective of the plan is to help local governments, fire departments, and residents identify at-risk public and private lands to better protect those lands from severe wildfire threat. Additional functions of the plan are to improve fire prevention and suppression activities, as well as to identify funding needs

A primary objective of the plan is to help local governments, fire departments, and residents identify at-risk public and private lands to better protect those lands from severe wildfire threat. Additional functions of the plan are to improve fire prevention and suppression activities, as well as to identify funding needs and opportunities to reduce the risk of wildland fire and enhance public and firefighter safety.

The Southern Gila County Community Wildfire Protection Plan was developed in response to the Healthy Forests Restoration Act of 2003 for the at-risk communities and unincorporated areas in southern Gila County, Arizona, located south of the Rim Country CWPP area and the San Carlos Apache Indian Reservation. Public lands within the CWPP analysis area are administered by the US Department of the Interior Bureau of Land Management Gila District Office, Tucson Field Office; the Tonto National Forest; and the National Park Service Tonto National Monument.

A comprehensive research program for the characterization of storm water runoff from an Arizona highway was conducted from January through December 2007. The study area covered a portion of the Loop 202 freeway west of Mesa Drive to a retention basin east of Lindsay Road in Mesa, Arizona. Storm water samples were collected from two storm water detention basins and a discharge point to the Salt River. The study was conducted by manually collecting storm water samples with passive automatic samplers and analyzing them for various roadway constituents. A primary objective of this research effort was to establish baseline values of constituents in ADOT highway runoff, aiding in the evaluation of related best management practices. A total of 16 storm water samples was collected from the research area between January 2007 and December 2007.

This project required the completion of Construction Data Forms for the Strategic Highway Research Program's (SHRP's) Specific Pavement Studies (SPS) Experiment Number 5, The Rehabilitation of Asphalt Concrete Pavements, and Experiment Number 6, The Rehabilitation of Jointed Portland Cement Concrete Pavements. In Arizona, the SPS-5 experiment construction was done in the eastbound travel lane of Interstate Highway 8, between mileposts 159 and 161 in southwestern Arizona. Eleven test sections were constructed for the experiment, with eight as set forth in SHRP guidelines. In addition, two additional sections were constructed, and one designated as the control section, for a grand total of eleven sections.

Description

This project was undertaken to compare operational and safety characteristics of leading versus lagging protected left turn operation. The measures of effectiveness included field measured intersection delay with leading and with lagging left turns.

This project was undertaken to compare operational and safety characteristics of leading versus lagging protected left turn operation. The measures of effectiveness included field measured intersection delay with leading and with lagging left turns. Intersections in Pima County, Glendale, Tempe and Mesa, Arizona were studied with both leading and lagging operation. Intersection delay studies were also done with first car versus third car actuation of leading protected left turn phases. Signal progression was studied with leading, lagging and combination of leading and lagging left turns which provided the best progression. This evaluation was accomplished with an instrumented vehicle and travel time runs throughout a grid. Accident studies were conducted in Tucson, Pima County and Scottsdale, Arizona. These studies compared accident frequency before and after the conversion from leading to lagging left turns. A public opinion survey was conducted to obtain motorists' preference of leading or lagging left turns.

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).
