Forgiving Roadsides Design Guide

A roadside is called unforgiving if hazardous objects such as trees are placed at an inappropriate distance from the road so that the risk of severe accidents is increased. The purpose of the 'forgiving roadside' concept is to avoid crashes of errant vehicles with potential hazards or to minimise crash consequences. The aim of this document is to collect and harmonise common standards and guidelines for roadside treatments. This report introduces typical roadside hazards, which are the basis for appropriate counter-measures. The main part of this report comprises results and findings from relevant literature, guidelines, and standards dealing with roadside treatments. The roadside features for which the Forgiving roadsides design guide has been developed are: barrier terminals, shoulder rumble strips, forgiving support structures for road equipment, and shoulder width. The different interventions proposed are linked to the potential effectiveness estimated and defined in the effectiveness study and in other relevant literature in order to allow the user to perform a cost-effectiveness evaluation before planning a specific treatment.
