PLANNING'S ROLE IN STANDARDS FOR FUTURE HIGHWAYS

MANY STATES HAVE PREPARED FUNCTIONAL CLASSIFICATION STUDIES. THESE STUDIES INVOLVE DETERMINING THE LEVEL OF SERVICE A ROAD IS EXPECTED TO PROVIDE AND EVALUATING FACTORS SUCH AS LENGTH OF TRIPS, SPEED OF OPERATION, DIRECTNESS OF ROUTING, DEGREE OF ACCESS CONTROL, DEGREE OF LAND SERVICE, AND FREEDOM OF MOVEMENT. HIGHWAY PLANNING ENGINEERS SHOULD DEFINE THE FUNCTIONAL CLASSES LISTING THE OBJECTIVES AND DESCRIPTIONS OF EACH CLASSIFICATION AND GATHER THE DATA USED TO DETERMINE THE CLASSIFICATION OF EACH HIGHWAY. DESIGNERS AND PLANNING ENGINEERS SHOULD COOPERATIVELY DEVELOP DESIGN STANDARDS REFLECTING THE DESIRED SERVICE TO BE PROVIDED BY EACH FUNCTIONAL CLASS. HIGHWAYS CAN BE CLASSIFIED INTO THREE BROAD GROUPS: ARTERIAL, COLLECTORS, AND LOCALS. ILLINOIS HAS CHOSEN HIGH DESIGN SPEEDS AN LEVELS OF SERVICE FOR THE ARTERIAL SYSTEM. THE HIGHEST CLASS OF ARTERIAL HAS FULL CONTROL OF ACCESS. THE DESIGN SPEEDS AND LEVEL OF SERVICE FOR COLLECTOR HIGHWAYS ARE LOWER THAN FOR ARTERIALS, AND THE LOCAL SYSTEM WOULD HAVE NO ACCESS CONTROL WITH NO REQUIREMENTS FOR LEVEL OF SERVICE. /AUTHOR/
