Safety Barriers

TRL Limited was commissioned by the Highways Agency to examine the performance and cost effectiveness of median barriers installed on major roads in Great Britain. This report consists of two inter related parts - a review of median barrier accidents which resulted in casualties, and the relative costs associated with median steel safety fences and concrete barriers. A detailed whole life costing survey for the most common types of safety fences and barriers currently in use on the median of major roads, is also included.

A study was also carried out to find out how the erection of temporary traffic management and permanent signing in the central reserve with concrete barriers should be managed.  This review covers both wide and narrow central reserves and also considers aspects relating to power supplies and services.

The reports relating to these studies are available for download below in PDF format.
