ARIZONA'S EXPERIENCE WITH SUFFICIENCY RATINGS

A POINT RATING SYSTEM IS USED BY ARIZONA HIGHWAY DEPARTMENT AND VARIOUS ENGINEERING ELEMENTS ARE GROUPED INTO THE CATEGORIES OF: CONDITION, SAFETY, SERVICE. THE METHOD ASSIGNS A POINT RATING TO EACH SECTION OF ROAD BASED ON THE ACTUAL CONDITION, OR SUFFICIENCY, OF THE ROAD AND ITS ABILITY TO CARRY THE TRAFFIC LOAD IN A SAFE AND EFFICIENT MANNER. THE RATINGS ARE TABULATED BY MECHANICAL MEANS AND ARRANGED IN ORDER OF PRIORITY WITHOUT REGARD TO ROUTE NUMBER, GEOGRAPHICAL LOCATION IN THE STATE, OR POLITICAL INFLUENCE. SINCE THE SUFFICIENCY-RATING METHOD WAS ESTABLISHED, PUBLIC HEARINGS ARE BRIEF AND ORDERLY. EXPERIENCE HAS DISCLOSED THAT ROAD-SYSTEM CLASSIFICATION MUST BE CONSIDERED IN ESTABLISHING A SUFFICIENCY-RATING PROCEDURE. THERE SHOULD BE A SEPARATE RATING TABULATION OF THE PRIMARY SYSTEM, THE FEDERAL-AID SECONDARY SYSTEM, AND THE URBAN SYSTEM.
