Minimizing Traffic-Related Work Zone Crashes in Illinois
This report presents the findings of a research project to study and develop recommendations to minimize work zone crashes in Illinois. The objectives of this project were (1) to provide in-depth comprehensive review of the latest literature on traffic-related work zone crashes and conduct site visits of work zones in Illinois, (2) to analyze the frequency and severity of traffic-related work zone crashes in Illinois, (3) to quantify the impact of layout parameters on the risk of crash occurrence and develop practical recommendations to control the factors contributing to work zone crashes in Illinois, and (4) to evaluate the practicality and effectiveness of adding temporary/portable rumble strips within and before work zones. To achieve these objectives, the research team carried out six major tasks: (1) conducting a comprehensive literature review, (2) collecting and fusing all available data and reports on work zone crashes in Illinois, (3) analyzing work zone crashes and identifying their contributing factors, (4) identifying the impact of layout parameters on the risk of crash occurrences and developing practical recommendations to improve work zone layouts, (5) performing field experiments to evaluate the efficiency of using temporary rumble strips in work zones, and (6) evaluating the effectiveness of temporary rumble strips before work zones begin and at the edge of work zones. During this study, the research team identified a number of promising research areas for further in-depth analysis and investigation: (1) investigating the practicality and effectiveness of using new prototypes of temporary rumble strips at the edge of work zones, (2) improving safety for construction equipment entering and exiting work zones, and (3) optimizing work zone transportation management plans (TMPs) to maximize work zone safety while minimizing total work zone costs.
