Delineation Effectiveness for Alcohol Involved Accidentsby Randolph W. Sanderson, Transport Canada, Ottawa, Ont, Canada,
Raymond A. Barton, Transport Canada, Ottawa, Ont, Canada,
Abstract: The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented here that engineering countermeasures to improve the roadway environment may more directly influence driver performance and contribute to reduced numbers of accidents. This paper will address the cost-effectiveness of roadway delineation as one of the engineering approaches to reduce night time single-vehicle accidents and particularly, those involving driver impairment. Current Canadian, American and European delineation practices, current research in the advancement of delineation devices and recommendations on effective maintenance standards will also be discussed.
