Abstract

Few accidents can be attributed entirely to any one factor, or group of factors, and for most accidents geometric standards play only a minor or indirect role. As a consequence, researchers have difficulty in isolating road geometry effects in the form of accident-geometry relations. Some success has been achieved in relating accident rates to cross-section width standards. This note summarizes some results of an investigation carried out by the author for The World Bank in which a number of accident-width relations given in the research literature were compared on a common basis using the relative difference approach proposed by Roy Jorgensen Associates.
