Evaluation of Traffic Safety in Construction Work Zones

The objectives of this research are to: (1) determine the crash rates for work zones; (2) determine the nature of traffic-related crashes in work zones and identify similarities and differences between nighttime and daytime crashes; (3) develop management practices that promote safety and mobility in work zones; and (4) develop work zone crash reporting recommendations to future improve the data collected on work zone crashes and improve safety requirements at work zones. This research reviewed and documented pertinent literature pertaining to work zone safety best practices, safety devices and initiatives. The research sought to perform an analysis of the factors that influence accident rates at work zones from a systems viewpoint. The results of this analysis aided in delineating factors from management best practices across the nation that would assist in specification of work zone characteristics to mitigate work zone accidents. In addition, various types of accidents (and accident reductions) were examined to quantify the benefits of implementing management practices that promote safety and mobility in work zones.
