Safety is one of the most important and complex aspects of transportation engineering. It takes a traffic professional considerable time and effort to keep abreast of research in the field of safety as it relates to traffic engineering improvements. Reading through research reports and summarizing the results is an overwhelming task; especially when having to identify the constraints of each study and relate them to the situation under evaluation. New studies and research findings are continuously presented and documented but not easily accessible by all transportation practitioners. Therefore, Transport Canada identified a need for a document that synthesized the safety impacts of various traffic operations and control strategies. The objective of this project was to assemble state of the art information from approximately the last ten years of research on the safety benefits of traffic engineering improvements. The final product would be a reference document providing, as much as possible, Canadian research information on the safety impacts of traffic control and operations that are most useful to transportation practitioners and other transportation professionals.
