• Abstract:
  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.
