 Description: According to statistics from the American Road & Transportation Builders Association (ARTBA), Florida is among the top three states for work zone fatal crashes with 73, 80, and 76 fatalities from 2015 to 2017, respectively. During this period, work zone crashes accounted for approximately 1.55% of the total crashes (i.e., 2,112,783 crashes), with 9,142 injury crashes. Another important aspect of work zones is worker safety. The worker fatalities in 2017 were 33.3% and 45.45% higher than 2016 and 2015, respectively. The objective of this project was threefold. First, the project investigated the contributing factors that affect the crash severity of work zone crashes associated with worker presence by time-of-day. Second, the project analyzed the variables that have significant impact on crash frequency as a result of work zone presence at bridge locations. Third, the project assessed the costs related to crash occurrence and crash severity due to work zone presence at bridge locations and quantified the contribution of ABC implementation to traffic safety compared with conventional construction. The outputs of this study provide insight to traffic safety experts for work zone crash analysis as well as to decision makers for more efficient bridge construction implementation.
