This research study addresses the collection, preparation, and use of traffic data required for pavement design by the Arizona Department of Transportation, focusing on data required as inputs for the American Association of State Highway and Transportation Officials "Mechanistic-Empirical Pavement Design Guide" design procedures. ADOT’s current traffic data collection and preparation processes are not adequate to meet the needs of the MEPDG procedure, and improvements are needed. These improvements include enhanced volume, classification, and weight data collection for vehicles, processing data and performing quality assurance checks, and the preparation/analysis of the data for use in the MEPDG. Use of the MEPDG in Arizona will require (1) an annual flow of updated key traffic data and (2) the ability to collect on-site (MEPDG Level 1) data in a timely manner for key projects.

The Arizona Department of Transportation, in coordination with Apache County District II and the Fort Defiance Chapter of the Navajo Nation, analyzed the traffic circulation conditions of Navajo Routes 7, 12, 54, 110, and 112 within the Fort Defiance Industrial Area which is designated as a major growth area on the Navajo Nation. The study was funded by the Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division's Planning Assistance for Rural Areas (PARA) program. The study was initiated to develop a planning strategy to improve the mobility and safety within the Fort Defiance Industrial Area.

The San Xavier District of the Tohono O’odham Nation is home to approximately 2,000 people. Numerous others come to the District to visit the San Xavier del Bac Mission Church. The San Xavier District Pedestrian Access and Safety Study is being prepared to improve the walking and bicycling environment on the San Xavier District for Community members and visitors alike. The study is being funded by the Arizona Department of Transportation Multimodal Planning Division’s Planning Assistance for Rural Areas program.

The collaborative process for developing the Tusayan Community Wildfire Protection Plan began May 5, 2004 at a Tusayan/Grand Canyon Chamber of Commerce Board meeting in Tusayan. A CWPP is developed to assist local fire districts, local governmental agencies and residents in the identification of lands—including federal lands—at risk from severe wildfire threat and to identify strategies for reducing fuels on wildlands while improving forest health, supporting local economies, and improving firefighting response capabilities.

The wild land/urban interface is a concern in Coconino County because of the potential for wild land fuels to ignite combustible structures and vice-versa. Destroying homes, property, and trees is just one way that wildfire harms an area. Wildfires can destroy habitat, soils, and forest health, disrupting economic stability, transportation corridors, recreation opportunities, water supplies, and scenery, as well as undermining a community’s emotional and spiritual well-being. Reducing the threat of catastrophic wildfire is a priority in the wild land/urban interface. This plan outlines actions needed to prepare and equip the greater Flagstaff community to live and thrive within our fire-adapted ponderosa pine forests.

19 members of the Granite Mountain Interagency Hotshot Crew died after being entrapped and burned over on the Yarnell Hill Fire in Yarnell, Arizona. The purpose of this document is to provide:
* A timeline of events that occurred between the time of ignition on June 28 and the entrapment and burnover on June 30;
* An analysis of the fire behavior and fire weather on June 30;
* A discussion of overhead management, strategies and tactics used on the fire, and documentation of decision points leading up to the entrapment and burnover that claimed the lives of the firefighters.

Following the completion of the 2005 report, an Act was passed that contained a number of important new and continued funding sources for safety related projects, programs, and initiatives. This required every state to develop a Strategic Highway Safety Plan. This 2007 report represents Phase 1, Development Plan and is a comprehensive, collaborative, high level, statewide safety strategy that will guide Arizona's safety change initiative. The Arizona Department of Transportation was assigned the role of project manager for this SHSP phase by the Governor's Traffic Safety Advisory Council.

The historical advantages of Grand Avenue and the railroad that led to the development of the West Valley cities have become a detriment to the further development or redevelopment in the past few decades. There is general agreement that significant improvements are needed for the Grand Avenue Corridor. Identified transportation funds provide an opportunity to develop a more modern transportation corridor along Grand Avenue. This study addresses these concerns by developing, evaluating, and recommending transportation investment options.

For a community to take full advantage of the opportunities provided in the Healthy Forests Restoration Act of 2003, it must first prepare a Community Wildfire Protection Plan. Maricopa County, partner agencies, and participating communities wish to adopt a Plan to better protect their communities from wildfire risk, to better prepare citizens, and to become eligible to apply for and receive federal and other grant monies to implement wildland fire mitigation and programs.

This study focuses in the area surrounding the municipalities of: Town of Pima, City of Thatcher and City of Safford. The junction of the two major state routes, US 191 and US 70 is located in the heart of these communities and serves as major arterials for local travelers. Parsons Brinckerhoff has been commissioned by ADOT to perform this preliminary assessment for the development of an alternate route through the Thatcher/Safford/Pima area.
