Multi-State In-Service Performance Evaluations of Roadside Safety Hardware
The evolution of roadside hardware in the past has been largely dictated by changes to
crash testing guidelines rather than observed field performance.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 332:
Multi-State In-Service Performance Evaluations of Roadside Safety Hardware
develops a unified format and nationally compatible
"in-service performance evaluation" (ISPE) methodology employing various individual state database parameters.
The document is supplemental to
NCHRP Research Report 1010: In-Service Performance Evaluation: Guidelines for the Assembly and Analysis of Data.
