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 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 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.

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.

Compiles information on plants and animals that are already recognized by the federal government as imperiled species, species which have been extirpated, and a much larger number of species that are in decline either locally or nationally. Descriptions of status, location, distribution, and habitat needs are presented for each species proposed. The report also considers vegetative communities, their history of decline and modification, and recommends priorities for their protection.

If one species had to be chosen to preserve and restore, perhaps it should be cottonwood. Cottonwood-willow forests, where they exist and are healthy, indicated the presence of a viable riparian area, which is in turn the key to conserving great proportions of our native species. A reflection of the dire status of our riparian systems is that the Sonoran cottonwood-willow and Sonoran mesquite-cottonwood forests.

Chronicles how the intention to conserve a relic population of Gila topminnow under current resource conditions is generally insufficient. We have let the resource base degrade too far to expect project and site specific responses to stem losses, much less lead to recovery. The Gila topminnow was considered to be among the most common of fishes in the Santa Cruz River system in the early 1940s. Three decades later is was considered endangered; and in another three decades time, its recovery is not foreseeable, given the piecemeal approach to protection efforts.
