Abstract
This report addresses recommendation 6.5b of the Working Group to Review the Standard for the Provision of Nearside Safety Barriers on the Trunk Road Network. This identified the need to understand more about how and where errant vehicles travel after leaving the nearside of the carriageway. The research has focussed on the factors that influence the travel of the errant vehicles, the relative significance of these factors, and potential ways to address them. Data on errant vehicle travel is needed both in the context of the post Selby action plan, and particularly to inform the risk assessment being developed for the revised standard for vehicle restraint systems.
