The Federal Highway Administration, in conjunction with U.K. and Australian highway administrators, created a standardized audit program referred to as the Road Safety Audit doctrine. The process ensures the safe management, now and in the future, of domestic and international highway development, with a goal of defining and creating a common planning baseline that supports the ultimate production of sets of safety-oriented highway design, production development and maintenance metrics.
Feasibility The feasibility phase establishes a general scope-of-work for the production of a master road project plan associated with a particular physical location and traffic mix. This phase includes necessary developmental elements, such as property access requirements, adjacent property limitations, potential scheduling needs and any expected or unexpected construction variances that could create a significant impact on the project's initiation and completion. The section's further broken-down by overall design, consideration of environmental constraints and a general element category applied as a placeholder if unforeseeable events require ad-hoc planning.
Project Assessment The project assessment element initiates the baseline engineering requirement and details considerations established during the feasibility stage. The assessment also delves into granular operational details, such as drainage needs, local climatic effects, required landscaping, emergency and safety access, and the construction scheduling and staging of local materials and equipment. During the design subcategory, the phase also defines primary engineering elements such as land-plot geometry, land cross-section engineering, land-grading needs, safe shoulder engineering, and operational impacts associated with potential departure from the plan's feasibility baseline.
Final Design The final design establishes a practical operational document that can produce a safety-oriented project management schedule. Elements articulated in the final design include the completion and vetting of any previous work-in-process tasks. Additionally, and to round out all critical categories, the phase investigates external issues, such as attention to the placement of any intersections, necessary non-vehicular infrastructure needs, the installation and placement of signs and lighting components, guardrails, necessary median designs and implementations, and any traffic constraints and management issues created during project development and construction.
Pre-Opening Just before opening of any corridor or road, the RSA serves as a final control check to ensure the appropriate and safe completion of all development task elements. Also used to validate final local or regional permitting for municipal and federal administrators, the pre-opening process calls for a review of all work-in-progress elements, from the initial tasks established in the feasibility phase to the final design phase.
