The objective of NCHRP (National Cooperative Highway Research Program) Project 22-7 is to update the recommended procedures for the safety performance evaluation of both temporary and permanent highway safety features in such a manner as to reflect advances in technology and accommodate current and anticipated roadway and vehicle characteristics. Key topics to be addressed will include the text matrix, data acquisition systems, data evaluation procedures, performance criteria, test condition tolerances, the use of surrogate test vehicles, computer simulation programs and other alternative procedures, and in-service evaluation procedures. An overview and status report of the project will be presented, with a view toward areas of potential harmonization with the European community.
