Conducting In-service Road Safety Operational Reviews of Temporary Traffic Control in Work Zones

This paper reviews the need for a formal procedure for conducting in-service road safety operational reviews of temporary traffic control (TTC) set-ups and discusses the methodology of conducting such reviews. This includes network screening / project selection, data requirements, review procedures and drafting the final report. Some of this methodology is currently being given by the Alberta Construction Safety Association in the Alberta Temporary Traffic Control short course, which outlines best practices with respect to designing, installing, maintaining and inspecting TTC set-ups. The focus of this paper is to provide information on conducting safety reviews of TTC set-ups in work zones.
