Development and Enhancement of In Service Performance Evaluation (ISPE) Process for Roadside Safety Devices
| 项目名称： | Development and Enhancement of In Service Performance Evaluation (ISPE) Process for Roadside Safety Devices |
| 摘要： | The purpose of roadside safety hardware is to reduce the risk of serious and fatal injuries to motorists in advertent road departures. Currently, in Texas, the performance criteria of those safety hardware, as having being detailed in MASH standards, are solely based on full-scale crash testing evaluation. TxDOT does not have a formalized process to perform in-service performance evaluation (ISPE) of roadside safety features. It is crucial to monitor roadside safety devices on Texas highways to ensure proper functioning after installation.This project will support TxDOT with setting and evaluating its level of safety risk and use quantitative information in the decision-making process. Researchers will (1) perform a literature review of other transportation agency ISPE procedures; (2) determine the level of ISPE that could be performed with the existing information currently in possess by TxDOT; (3) provide TxDOT with appropriate recommendations for changes or improvements to complement existing information, and review crash data, information collection methods, and asset inventory, so as to improve ISPE quality, reduce performing work hours, and enable ISPE on additional devices; and (4) develop a guidance document. The results of this project will obtain a TRL level 4. |
