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.

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.

Phoenix Early Head Start (EHS) is a program for first-time teen parents and their families. It is a family-centered program intended to provide early, continuous, intensive, and comprehensive child development and family support services for vulnerable families and their very young children. This report presents case studies of 12 families, all EHS participants, who agreed to be followed throughout their participation in the program so that their stories could be updated as they unfolded from one year to the next. The case study families were interviewed for the first time in August 1997 and again in August 1998. Common themes in the family's stories regarding EHS's role include: (1) assistance from caring staff; (2) reassurance from home visits and child development; (3) help in becoming good parents; (4) help with personal goals; (5) help with daily life; and (6) socialization opportunities for children and parents.

This publication updates the January 2004 study, New Returns on Investment in the Knowledge Economy: Proposition 301 at Arizona State University, FY 2003. Both works were launched by the report, Seeds of Prosperity: Public Investment in Science and Technology Research (2003), by Morrison Institute for Public Policy. Morrison Institute will periodically publish new material to keep you informed of the status of Proposition 301 investments at Arizona State University.

The Phoenix, Arizona Early Head Start program is a family-centered program providing early, continuous, intensive, and comprehensive child development and family support services for low-income pregnant women and families with children ages birth to three. Analyses were conducted of program and participant data and program processes from Year 3, the second full year of implementation. The program components evaluated were: (1) child development, promoted through weekly home visits, site-based socialization activities, and weekly play groups; (2) family development services, provided by family support specialists to develop effective, supportive relationships, especially with fathers; (3) staff development, incorporating a multi-disciplinary approach reinforced by a relationship-based supervision model; and (4) community building and collaboration, including connections with Phoenix's program for young fathers and other family-focused initiatives.

Evaluation findings suggest that the program is on the right track. Among the program's successes are the launch of all planned child development activities, increased services by and access to the child development/disabilities specialists, and progress made through the male involvement component. The program continues to face challenges, including increasing staff skills in child development and parent-child relationships, helping young parents adjust to dealing with toddlers, reducing disruptive effects of staff turnover, and making the program and participants visible and vital to other family-centered community endeavors and to policy makers. Recommendations for future operations were derived from the evaluation findings. (Contains 49 references.)

Amidst the numbers and statistics that comprise a program evaluation, it is easy to lose sight of the program participants themselves. That is one rationale for a case study--to tap into some of the rich background information that only participants can provide. To develop some of this background information for the five-year program evaluation of Phoenix Early Head Start(EHS), a case study was undertaken of 12 families who were representative of all EHS program participants. Each of the 12 families agreed to be followed throughout their participation in the program so that their "stories" can be updated as they unfold from one year to the next.
