Why is it important?
Work zones have been a high-priority issue due to their impacts on traffic safety. A better understanding of work zone crashes can help to identify the contributing factors and countermeasures in order to enhance roadway safety. Florida is among the top three states across the nation with the highest fatality rates. Miami-Dade County had the highest crash rates in the state of Florida, with a total of 64,070 fatality and injury crashes in 2016. The number of work zones has increased due to the growth of highway renovations and construction projects in the state of Florida. The number of crashes associated with work zones increased from 1,153 in 2013 to 1,315 in 2017. Thus, safety should be an important consideration by decision makers; as they plan, design, and operate the work zone.
