Appendix A: Longitudinal Barriers
Anchor: #CHDJIDADSection 1: Overview
Anchor: #i1005148Introduction
The objectives of this appendix are to make available data and guidelines for the use of roadside and median traffic barriers in a consolidated and understandable form. These guidelines should be supplemented by sound engineering judgment.
The area adjacent to the traveled way plays an important role in the safe operation of a facility. Crash statistics show that a significant portion of crashes on rural roads are the single vehicle, run-off-the-road type. Provision of an obstacle-free zone and the effective use of barriers to shield obstacles that cannot otherwise be removed or safety treated are important considerations for enhancing safety performance.
