Diagram of types of Road Safety Audits Grouped by Phase and Stage
Diagram of types of Road Safety Audits Grouped by Phase and Stage. The diagram illustrates a method of grouping RSAs by phase and by stage. The first RSA phase illustrated is the Pre-construction Road Safety Audits. This phase is made up of the Planning, Preliminary Design and Detailed Design RSA stages. The second RSA phase illustrated is the Construction Road Safety Audits. This phase is made up of the Work Zone, Construction and Pre-Opening RSA stages. The third RSA phase illustrated is the Post-contstruction Road Safety Audits. This phase is made up of the Existing Roads RSA stage. The forth and final RSA phase illustrated is the Development Project Road Safety Audits. This phase is made up of the Land Use Development RSA stage. The diagram also illustrates that RSAs applied early in the planning and preliminary design of roads offer the greatest opportunity for benedicial influence. As a design progresses into detailed design and construction, changes that may improve safety performance typically become more difficult, costly and time-consuming to implement.
