ABSTRACT (Maximum 200 words) This is the final report describing work performed by the National Institute of Standards and Technology (NIST) to develop the objective test procedures and the supporting measurement methodologies for evaluating Objective Test Procedures for Road Departure Crash Warning Systems (RDCWS). Included with the final report are three separate documents. The first document, titled “Final Report: Objective Test Procedures for Road Departure Crash Warning Systems (RDCWS)” is an overview of the project and results. The second report, “Recommendations for Objective Test Procedures for Road Depar- ture Crash Warning Systems,” contains test procedures recommended for a warning system that meets the requirements of the RDCWS FOT. The third document, entitled “An Independent Measurement System for Performance Evaluation of Road Departure Crash Warning Systems,” provides a detailed description of a measurement system developed by NIST for use in evaluating the performance of the FOT RDCWS during track-based and on-road tests. 14.

In response to the large number of crashes and the public’s interest in safer automobiles, the automotive in- dustry is developing advanced Road-Departure Crash Warning Systems (RDCWS) to ad- dress this type of crash (as well as others, such as rear-end and lane-change collisions).
