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.

In spring 1998, 1,057 10th-grade students were surveyed as one component of a statewide evaluation of Arizona's school-to-work system designed by the Morrison Institute for Public Policy. This second survey measured attitudes toward and participation in career activities. Results were compared to baseline data collected from over 2,000 10th-grade students in 1997. Data indicated that, in both years, nearly all students had at least an idea of their career area of interest; gender differences were observed in students' selections of career interests. Student participation in activities increased. Statistically significant differences in participation by sex were evident: more girls reported learning about careers in class and participating in volunteer activities; and more boys participated in internships with pay, worked for pay in a job unrelated to their careers, and had business mentors. The share of students who had selected a career interest increased as participation rose. All 14 activities were at least "somewhat" helpful to students in making career selections. In both years, students ranked family, teachers, and friends most highly as influencing career interests. One-fourth of students in 1998 compared to one-third of students in 1997 indicated they never received career guidance at school. Less than one-half of students were aware of courses related to career interests; even fewer actually took a course related to their interests.

One component of a multi-faceted evaluation of the state's STW initiative involves surveying tenth grade students. Thus, the survey was designed to assess the extent to which Arizona tenth grade students have selected career majors, planned a course of study for high school and beyond, and received adult guidance related to careers. As part of the evaluation, the intent was to look at the extent to which career preparation and work experiences truly are system-wide and impact students. In contrast, the purpose was not to evaluate whether STW program participants are receiving school-based learning components.

Tenth-grade students in Arizona school to work (STW) regional partnerships were polled in 1997, 1998, and 1999, to determine whether systemic change was occurring across the state. Study results were mixed. Three activities increased significantly over the baseline year: class projects, computer use, and volunteerism. The use of career inventories declined over the same period. The role of adults in helping students explore career choices remained relatively stable. Further, the number of students who had some idea of their career interests had not changed significantly. Gender differences still existed and were largely unchanged. Fewer students reported taking courses related to their career interests. The relationship of participation in career-related activities to an ability to state a career interest continued to be strong. Students felt job shadowing, business mentors, and internships would be most helpful. However, fewer students participated in these activities. The participating students were better able to articulate their career interests and, in general, had more frequent and positive attitudes about participation in STW. Statewide programs reported positive student outcomes as a result of STW activities. Evidence of systemic change was beginning to be seen. Most significantly, class projects, computer use, and volunteer projects showed consistent gains over the three years.

One component of a multi-faceted evaluation of the state's STW initiative involves surveying seventh grade students regarding career awareness and career exploration and counseling in order to help students who may be interested to identify, and select or reconsider, their interests, goals and career majors, including those options that may not be traditional for their gender, race, or ethnicity.

In spring 1998, 1,020 seventh-grade students were surveyed as one component of a statewide evaluation of Arizona's school-to-work system designed by the Morrison Institute for Public Policy. This second survey measured attitudes toward and participation in career activities. Results were compared to baseline data collected from over 2,000 seventh-grade students in 1997. Data showed that student participation in activities increased. Top-ranked activities were the same in both years: classroom speakers, discussions with adults, class projects, field trips, and job shadowing. In both years, more than 60 percent said at least one activity helped them think about choosing a career; roughly 35 percent indicated having a definite idea of what they want to do in the future; and student participation in various activities was positively related to their ability to define a career interest. In both years, mentoring by other adults was up, whereas mentoring by school personnel had decreased. Students who talked to adults about their careers were significantly more likely to have identified a career interest. In both years, fewer boys were apt to report any adult talked to them about careers. The number of students who planned to take classes in high school that teach job skills showed a statistically significant decrease. Girls were more certain they would take classes. In both years, about one-third of students agreed some jobs are best for women, and some for men; boys agreed most often.
