This paper presents an overview of work zone crashes in Brazilian federal highways undergoing lane addition. For the purpose of the study, nine segments of highway construction under the jurisdiction of DNIT were analyzed throughout several states in Brazil during the year of 2013. The results show that the accident rate per kilometer in work zone stretches was higher than the accident rate across the entire paved network. While the paved roads had a rate of 2.44 crashes per kilometer, the assessed work zone stretches showed a rate of 4.06 crashes per kilometer. Furthermore, the rate of crashes with injuries and deaths was higher in segments with work zones. This situation can be minimized by implementing more efficient signaling in these segments, as well as the adoption of ITS, seeking to ensure the safety of road users and traffic flow.
