Local Road Management Manual 128 Stage 1: Feasibility or Conceptual Development Stage. An RSA at this stage can influence route layout or intersection treatment options. It assesses the relative safety performance of alternative schemes and reveals the safety needs of various road users. It may also influence changes in nearby road networks to accommodate changes in traffic; Stage 2: Preliminary Design Stage. At this stage, route and intersection design options have been determined. The RSA deals with issues such as intersection or interchange layouts and the chosen standards, and is carried out after the final alignment is chosen. A single audit of stages 1 and 2 is sometimes performed, depending on the complexity of the project and the need for land acquisition; Stage 3: Detailed Design Stage. The geometric design, traffic signage scheme, and plans for pavement marking, lighting, and landscaping are available at this stage. The RSA examines safety features such as sight distance, pedestrian safety, and vehicle conflict points in relation to the operation of the road; Stage 4: Construction Stage. During construction, the RSA team inspects all relevant conditions (e.g., day and night) on the site. This site inspection, on foot or by car or bicycle, is done to ensure that earlier audit concerns are being addressed during construction and to check for hazardous conditions that may not have been apparent during the design stages; Stage 5: Preopening (Roadwork Traffic Management Planning) Stage. RSAs on roadwork traffic management schemes expose road safety issues that may be created by a changing speed environment, confined space or alignment, roadside hazards, additional conflicts, and temporary signage arrangements during the construction of road works; and Stage 6: Operating Stage. RSAs on sections of the existing road network reveal road safety hazards before they lead to accidents. Even though some roads may have been audited when they were built, traffic patterns and the use of the road may have changed since then.
