Because traffic incidents create unexpected driving conditions, traffic safety issues can arise. In particular, unexpected traffic incidents could require drivers to decelerate rapidly, causing an unsafe situation. Because the emerging connected vehicle (CV) concept can enable sharing of real-time information and help drivers to change their driving path, lane, or speed; CVs could avoid rapid decelerations caused by unexpected traffic incidents. This study evaluated the impacts of CVs on traffic safety near traffic incidents. The researchers used VISSIM 8 to simulate a 17-mile segment of Interstate 55 in Illinois, modelling 10 different incident scenarios, and measuring the deceleration rate of vehicles approaching an incident scene. The results from this study indicate that CVs have the potential to reduce the proportion of vehicles that rapidly decelerate near incident scenes along a freeway. Reducing the number of vehicles that rapidly decelerate is expected to reduce secondary crashes and improve safety.
