摘要：	Nationally, work zone fatalities peaked at over 800 per year during the 1990’s. Arizona tallied 82 fatal and 5,009 injury accidents in work zones during a five year period. In response to this problem, the objectives of this project included:- Characterizing the nature of work zone accidents in Arizona Reviewing countermeasures used throughout the country, and the effectiveness of those countermeasures Recommending countermeasures for use in Arizona to improve work zone safety and reduce accidents Work zone accidents account for about 3 percent of all reported accidents in Arizona, or about 3,000 work zone accidents per year. These accidents produce about 18 fatalities and 1,600 injuries per year. Compared to all accidents statewide: work zone accidents tend to be less severe: larger vehicles tend to be over-represented in work zone accidents: a greater proportion of work zone accidents occur in rural areas: and work zone accidents are over-represented on the State Highway System. A detailed analysis of fatal accident reports did not clearly identify any common or widespread factors that contribute to fatal accidents occurring in work zones. A national review of work zone countermeasures was conducted, focussing on the documented effectiveness of various work zone countermeasures. To identify which countermeasures are most appropriate for use in Arizona, a panel of 21 experts was convened. The panel included representatives with a variety of perspectives on the work zone accident problem. ADOT personnel dealing with construction operations, maintenance, traffic operations, safety, and research were represented. Department of Public Safety officers, construction industry representatives, a traffic control contractor, an FHWA representative, and university researchers also attended. The panel selected six principal countermeasures for implementation in Arizona; 1) Work Zone Speed Limits; 2) Police Presence; 3) Speed Limit Enforcement; 4) Public Education: 5) Sign Credibility: and 6) Temporary Pavement Markings in Work Zones
