In-Service Performance Evaluation of Median Cable Barrier in Iowa

The objective of this project is to conduct an in-depth analysis of the effectiveness of Iowa's Interstate median cable barriers. This effort should result in a comprehensive document describing the performance of the barriers. Activities in this effort will include: (1) Benefit/Cost analyses taking into account: Crash experience, Construction costs, and Maintenance and repair costs; (2) Comparison of: Barrier location/offset; and (3) In-Depth analysis of: Large truck crashes, Motorcycle crashes, and Secondary crashes. The proposed work includes six primary tasks: Task 1. Conduct State-of-the-Art Literature Review; Task 2. Collect Crash, Roadway Segment, and Environmental Data; Task 3. Review and Analyze Crash Data; Task 4. Collect Installation and Maintenance/Repair Cost Data; Task 5. Examine Program Effectiveness and Cost-Effectiveness; and Task 6. Develop Guidelines and Final Report.
