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.

Through surveys and interviews, this publication reveals that parents – regardless of income, education levels and ethnic background – basically want the same things from their child care providers: a safe, nurturing learning environment. The study also reveals that many parents face challenges in finding information about child care options in their communities, care that meets all of their expectations, and resources to pay for early learning programs.

This report provides baseline report on the current state of parents’ knowledge about children’s early development and parents’ perceptions of the resources currently available for young children and their families in Arizona. The results help identify parents’ current knowledge about early development as well as the areas in which families need additional support to access needed services for their child/children.

For kids 5 and younger in early learning programs, success is largely determined by the knowledge and skills of their teachers, and by the quality of the interactions with those educators. This publication describes how Arizona continues to struggle in educational attainment, wages and retention of its early learning workforce. It also offers recommendations for parents, providers, policymakers and other stakeholders on how we can all better support those responsible for helping infants, toddlers and preschoolers get ready for school and set for life!

There are two distinct components to the economic development activities described in ADOH’s LIHTC program details. The first component is activity that strengthens the economy. This is the quantifiable activity that is the subject of this report. The second component is community building activity which can be both quantitative and qualitative. This is an area that should be considered in the debate but which is not addressed within this report.

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.
