NCHRP Project 22-64: Method for Using ISPEs in Crash-Testing Protocols
The objective of this project is to investigate how state DOTs can incorporate collected ISPE data and results in commonly used crash-testing protocols for roadside safety hardware.
NCHRP Project 22-58: National In-Service Performance Evaluation Guidelines for Defining Acceptable Roadside Safety Hardware
The objective of this project is to develop ISPE guidelines to define and recommend nationally acceptable field performance criteria for roadside safety hardware based on the evaluation measures within NCHRP Research Report 1010.
NCHRP Project 22-63: Verification and Validation Guidelines to Use Computer Simulation as an Alternative to Full-scale Crash Testing
The objectives of this study are to: (1) establish a standardized confidence-level based process to verify and validate computer simulations of roadside safety devices across the different roadside safety hardware categories and test levels, and (2) design a uniform reporting template for detailing the inputs and outputs of the computer models used.
Study on Steel Barrier Systems (Task Order 421)
The New Jersey Department of Transportation (NJDOT) initiated this study to evaluate temporary steel barrier systems as alternatives to conventional concrete barriers in highway work zones. Led by Rutgers University in collaboration with Roadsafe LLC and Rowan University, the research examines crashworthiness, barrier deflection, anchorage requirements, and compliance with the Manual for Assessing Safety Hardware (MASH). The project combines a literature review, a nationwide survey of state transportation agencies, and an evaluation of crash test data to assess available steel barrier systems. The findings will support performance-based selection criteria and help expand barrier options for highway construction and bridge rehabilitation projects.
