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.

In the mid‐1990s, the Arizona Department of Transportation initiated the Maintenance Cost Effectiveness study (SPR 371) with the development of plans and an experiment design to evaluate the effectiveness of a variety of asphalt pavement maintenance treatments. During 1999 and 2001, ADOT oversaw the construction of hundreds of experimental sections throughout the state under the Phase I, Wearing Course Experiment (nine treatments and 82 sections at three sites), and the Phase II, Preventive Maintenance Experiment (24 treatments and 137 sections at four sites). Work continued in 2006 and 2007 under the Evaluation of Maintenance Strategies study (SPR 628) for ADOT with a yearlong program of pavement performance monitoring involving manual pavement distress surveys and automated skid, friction, and surface texture measurements at all the experimental sites. The project culminated with a detailed analysis of key pavement performance data to compare the performance of the individual treatments and determine their overall effectiveness. This report documents the independent findings of both the Phase I and II experiments.

RTI International is working on behalf of the Arizona Department of Health Services’ Bureau of Tobacco and Chronic Disease to identify existing tobacco-related data and data needs. RTI interviewed ADHS-BTCD’s partnering organizations by telephone and conducted an environmental scan of existing public use datasets. This report describes the results obtained from the environmental scan and the partner telephone interviews, and it discusses recommendations for addressing the identified data gaps.

The Maricopa County Department of Public Health and the Southwest Interdisciplinary Research Center at Arizona State University initiated an evaluation of ASU’s Tobacco-Free Campus policy, which went into effect on August 1, 2013. The purpose of this evaluation is to assess the impacts of this policy on the ASU community and environment. This report summarizes tobacco consumption patterns, norms and perceptions surrounding tobacco use, tobacco litter on campus, and overall benefits of a tobacco-free campus both before and after policy implementation.

In 2006, the Smoke-Free Arizona Act outlawed smoking within most enclosed public spaces and places of employment primarily to reduce the exposure of individuals to harmful secondhand smoke. The purpose of the Maricopa County Smoke-Free Parks Policy Assessment is three-fold: 1) to evaluate the extent and health impact of tobacco usage in public parks; 2) analyze smoke-free parks policies that have been proposed in cities, counties, and states nationwide; and 3) to assess the feasibility of introducing and implementing similar policies in Arizona, and in Maricopa County in particular.

The Arizona Department of Environmental Quality asked the Arizona Department of Health Services to evaluate the health threat to residents from exposures to ash fallout from a fire at an asphalt plant located on the Salt River Indian Reservation in Mesa, Arizona. The facility has recently been bought by Vulcan, Inc. The site is located just north of the Salt River between Dobson and Alma School Roads. April 13, 1999.

This public health assessment evaluates the potential public health hazard from exposure to contaminated groundwater in the vicinity of the Tucson International Airport. The Tucson International Airport Area superfund site consists of a main plume of contaminated groundwater and three smaller areas of groundwater contamination east of the main plume. This report focuses on one of these areas of contamination called Plume B and evaluates the public health hazard posed by Plume B to residents of the area of south Tucson bounded by Valencia Road, Campbell Avenue, Irvington Road, and 6th Avenue.

The United States Environmental Protection Agency asked the Arizona Department of Health Services, Office of Environmental Health, to provide an evaluation of the health hazards that may result from exposure to soil and soil gas contaminants present on the West-Cap site, located just north of the Tucson International Airport. Improper waste disposal practices from previous industrial activities at the site have resulted in contamination of on-site soil and soil gas. The objective of this health assessment is to assess the potential adverse health impact to on-site workers from exposure to the on-site contaminated soil and soil gas. Community exposures are not presented in this public health assessment.

The Agency for Toxic Substances and Disease Registry has asked the Arizona Department of Health Services, Office of Environmental Health, to conduct a health assessment for the off-site residential area located adjacent to the Tucson Industrial Center, also known as the 3 Hangars site, within the larger Tucson International Airport Area Superfund site, in Tucson, Arizona. Previous investigations found that elevated levels of polychlorinated biphenyls (PCBs) in the drainage areas at the TIC site had migrated off-site into residential areas presenting a health threat to residents. The purpose of this Public Health Assessment is to evaluate if a public health hazard still exists since the remediation activities have been conducted at the off-site El Vado residential area. ADHS concludes that no current public health hazard exists as a result of ingestion, dermal, or inhalation exposures by residents, children, or transients to the post remediated soil in the residential areas on El Vado Road. Replacement of the top soil with certified clean soil has removed all contact with the soil containing PCBs eliminating any future public health hazard.

The Arizona Department of Health Services prepared this report to evaluate whether a public health hazard exists as a result of potential environmental exposures from the contamination at the Phoenix Goodyear Airport North site. Another objective of this report was to investigate and address the health concerns of the residents in the Goodyear area, including former Unidynamics workers. This report uses available environmental data from the site and information collected from members of the community regarding their health concerns. There were many concerns, including health concerns, of residents and former Unidynamics workers that were related to living near the PGA North site or previous employment at the former Unidynamics facility. These community concerns are identified and addressed in the public
health assessment.
