Identification of Over-Represented Parameters for Work Zone Crashes in Alabama, Michigan, and TennesseeAuthor/Presenter: Chambless, Jil; Belou, Laura; Lindly, Jay K.; McFadden, John
Much roadway maintenance and construction work takes place in the presence of traffic, which is often traveling at high speeds. A reasonable goal is for work zones to pose no greater safety risks for motorists than non-work zone areas. Another is to minimize safety risks for workers due to exposure to traffic. Paying attention to the differences in work zone and non-work zone crash characteristics can help to direct safety enhancement efforts. This paper discusses not only characteristics that occur with the highest frequency, but also those that are over-represented or under-represented in work zone crashes when compared to non-work zone crashes. Work zone crash data in Alabama, Michigan, and Tennessee were reviewed and found to have many common characteristics.
