Wire Rope Safety Barriers and the Pacific Highway Program: RTA Research and Investigations

This paper discusses the decision process used by the Roads and Traffic Authority NSW to determine the type of median safety barrier that is most appropriate for reducing the risk of accident trauma on two-lane sections of the Pacific Highway. It shows the method used to quantify the predicted risk reduction after implementation of the proposed upgrade program, and compares the predicted results with those of 5- years experience with median wire rope safety barriers in Sweden. It also shows the process used to determine the minimum median width for installation of median wire rope safety barriers.
