Severe causalities and property damages caused by work zone related accidents call for a technological reform that can resolve the problem. As a result, the Vehicle Infrastructure Integration (VII) program, a major intelligent transportation systems (ITS) initiative, seeks to revolutionize transportation by creating an enabling communication infrastructure between vehicles and roadside to provide significant safety, mobility and commercial benefits. This research plans to design a VII technology-based system for improving the safety performance of work zones and test the effectiveness of the proposed system by driving simulator experiments. The proposed VII based system includes an in-vehicle driver warning subsystem and a real-time Dynamic Message Sign (DMS) subsystem. To test the effectiveness of the proposed work zone collision prevention system, three types of driving scenarios were generated. Qualitative data from surveys and quantitative data from driving tests were both collected for assessing the safety benefits of the proposed VII-based work zone collision prevention systems. The results of this research indicate that VII technology has the potential to reduce the safety risks at work zones under certain conditions. The results of this research will also be beneficial in deciding the application of VII technology.
