• Abstract:
  The United States experiences over 700 fatalities and over 37,000 injuries each year in temporary ; construction and maintenance work zones. The Federal Highway Administration (FHWA) has implemented ; Temporary Traffic Control Devices 23 CFR 630 Subpart K, which specifies a state highway agency must ; amend their state safety and mobility plan by 2008 to include a description for positive protection in work ; zones and implementation guidelines for federal funded highway projects. This research study first ; investigated temporal trends in national and Kansas work zone related crash trends, specifically crashes ; involving striking a construction vehicle or fixed object. Additionally, current work zone TL-3 and TL-2 ; approved positive protection devices were summarized including longitudinal barriers, mobile barriers, ; vehicle arresting systems and end protection systems. Next, a nation-wide survey of state highway agencies ; was conducted to summarize current guidance relating to positive protection or changes in guidance to ; comply with Temporary Traffic Control Devices 23 CFR 630 Subpart K. Finally, the research study ; provided preliminary work zone positive protection guidance for the Kansas Department of Transportation ; based on the findings of the survey and currently available products.
