The work described in this report is part of a research programme aimed at developing methods of identifying and improving high-risk interactions between vehicles, roading situations, and drivers. The goal of the present experiment was to develop and demonstrate an analysis tool that would allow road safety professionals to compare the effectiveness of a range of road safety engineering treatments, including treatments with implicit and explicit features, as they related to a specific road with a known pattern of crashes. This work involved two distinct phases of enquiry: first, selection of a road with a well-documented history of crashes and analysis of specific sections of the road as regards their amenability to various road safety treatments; second, a comparison of the treatments’ effectiveness by means of an accurate three-dimensional recreation of the road in a driving simulator and a representative sample of drivers.
