In Service Evaluation of Railroad Signal and Stop Arm Pole Protection
| 项目名称： | In Service Evaluation of Railroad Signal and Stop Arm Pole Protection |
| 摘要： | This study will address the need for providing steel beam guardrail to protect railroad poles. The proposed work is comprised of the following tasks: Task 1. Literature Review; Task 2. State-of-the-Practice Review; Task 3. Data Collection; Task 4. Statistical and Economic Analyses; and Task 5. Prepare Final Project Report. The goals of this study are: (1) Determine the crash rate into railroad poles without steel beam protection and compare to those with steel beam protection to determine if protecting against this hazard is actually reducing injuries; (2) Determine the benefit/cost ratio for protecting with steel beam guardrail or crash cushions given the crash rate per vehicle in relation to annual average daily traffic (AADT); (3) Determine what railroad pole designs are breakaway, if any, such that they are designed to safely break away during a crash and thus would not warrant protection; and (4) Survey State departments of transportation (DOTs) to determine best practices if a positive benefit/cost ratio is unattainable for a given AADT and the railroad pole is not breakaway. |
