Abstract:
The procedure detailed in this paper was designed to develop a statement of the sufficiency of the existing roadway system with respect to operating, physical, and safety aspects. Roadway elements evaluated include intersections, links, bridges, railroad grade crossings, and high-hazard locations. The statement of existing conditions identifies needs that are the basis for a remedial-action analysis that leads to the development of an improvement-implementation program. A two-stage screening analysis is used. The first level is based on broad performance criteria and separates roadway elements into two groups--those obviously adequate and those requiring closer study. The second level serves two purpose: it further screens out elements that are adequate, and it identifies and quantifies the deficiencies of those elements found to be inadequate.
