National Guidance for Defining Acceptable Roadside Hardware Field Performance through In-Service Performance Evaluations (ISPEs)
| 项目名称： | National Guidance for Defining Acceptable Roadside Hardware Field Performance through In-Service Performance Evaluations (ISPEs) |
| 摘要： | One reoccurring theme in re-writing crash test and evaluation procedures over the last 40 years is the recommendation to conduct in-service performance evaluations (ISPEs) of roadside safety features. The laboratory performance of roadside safety hardware is tested and evaluated using criteria published in MASH (define). The site location and installation of roadside safety hardware is guided by criteria published in the AASHTO Roadside Design Guide (RDG). ISPE criteria has only just become available under NCHRP Project 22-33, “Multi-State In-Service Performance Evaluations of Roadside Safety Hardware” Guidance is needed, at the national level, for defining acceptable field performance. The objective of this research is to develop guidance that defines acceptable field performance thresholds for roadside hardware. Performance thresholds defining acceptable performance should be developed for each of the evaluation criteria established under the NCHRP Project 22-33. Guidance for the use of ISPEs for establishing or updating existing guidelines and for establishing crashworthiness should also be developed. The research will produce information to better understand and more consistently evaluate the field performance of roadside hardware. |
