A Case for Science-Based Road Safety Design and Managementby Ezra Hauer, Univ of Toronto, Canada,
Abstract: What civil engineers do has a major effect on road safety. However, contrary to appearances, the level of safety built into roads is largely unpremeditated. Standards and practices have evolved without a foundation knowledge. At times the safety consequences of engineering decisions are not known, at others some knowledge exists but is not used. In this paper I attempt to describe the current, unsatisfactory, state of affairs. I explore some of its root causes and speculate what needs to be done to change course.
