Multi-State In-Service Performance Evaluations of Roadside Safety Hardware

The objective of this research was to develop a unified format and national compatible ISPE methodology employing various individual state database parameters. The implementation of the methodology was to include an electronic tool, guidance document, and training for performing an ISPE on roadside safety hardware devices either by a corridor or system type analysis. The results of the developed ISPE methodology were to be demonstrated and verified by a pilot effort, which were to include hosting a workshop and post workshop technical support to selected states. The workshop was to provide a pilot implementation training program and training materials to demonstrate the new protocol and identify any common issues and challenges of conducting a multi-state ISPE on selected roadside safety hardware devices for state transportation agencies, such as but not limited to various data parameters, limitations and measures of effectiveness. The guidance is intended to be used by state transportation agency officials. The research was to build upon previous work, provide guidance, and address the opportunities, challenges, institutional barriers, and associated costs of a state and a multi-state ISPE.
