ESTABLISHING PRIORITIES FOR COUNTY ROAD PLANNING

SINCE NEEDED CONSTRUCTION PROJECTS USUALLY EXCEED THE FUNDS ALLOTED, A METHOD OF PRIORITY PROGRAMMING HAS BEEN TESTED WHEREBY EACH HIGHWAY IS CLASSIFIED AS (1) PRIMARY ARTERIAL, (2) SECONDARY ARTERIAL, AND (3) ACCESS ROADS. IN TURN, EACH THREE TO FIVE MILE SECTION IS GIVEN A CONDITION RATING (CR) AND A SERVICE RATING (SR). THE CR ENCOMPASSES PAVEMENT WIDTH 10, SHOULDER WIDTH 10, ALIGNMENT 10, GRADE 10, SAFE PASSING SITE DISTANCE 10, SURFACE RIDING QUALITY 10, STRUCTURAL ADEQUACY 20, AND DRAINAGE ADEQUACY 20 TO TOTAL 100. THE SR INCLUDES FOUR BROAD AREAS: ECONOMY, RECREATION, SERVICE, AND COMMUNITY. THE SUM OF THE AVERAGE DAILY TRAFFIC (ADT) AND THE ACTUAL TRAFFIC COUNT REPRESENTS THE SR FOR THE ROUTE. THE PRIORITY RATING (PR) IS COMPUTED AS FOLLOWS: PR = 2.5 (SR) EXPONENT 1.25 X LOG 100/(CR).
