HIGHWAY PLANNING SURVEY DATA ARE USED IN THE TRAFFIC ENGINEERING AND SAFETY WORK OF THE HIGHWAY DEPARTMENT FOR: (1) TRAFFIC VOLUMES AND TYPES WHICH GOVERN THE CLASSIFICATION OF THE HIGHWAY SYSTEM, WHICH DETERMINES THE DESIGN SPEED, MAXIMUM CURVATURE, MINIMUM SIGHT DISTANCE, NUMBER OF LANES, LANE WIDTH, (2) DIRECTIONAL VOLUME COUNTS, BY TYPE OF VEHICLE TO DETERMINE INTERSECTIONAL DESIGN, (3) DIRECTIONAL VOLUME COUNTS, VEHICULAR AND PEDESTRIAN, SUPPLEMENTED BY EXAMINATION OF ACCIDENT RECORDS TO DETERMINE THE JUSTIFICATION, IF ANY, FOR SIGNAL CONTROL AT INTERSECTIONS, (4) CULTURAL DEVELOPMENT SUPPLEMENTED BY VOLUME COUNTS, SPEED DETERMINATION, AND ACCIDENT RECORDS FOR THE ESTABLISHMENT OR ELIMINATION OF RESTRICTED SPEED ZONES, (5) DATA ON DEGREE OF CURVATURE TO BE USED IN THE MARKING OF THE SAFE SPEED ON CURVES, (6) DATA ON VEHICLE MILES OF TRAVEL SUPPLEMENTED BY ACCIDENT RECORDS TO DETERMINE HIGH ACCIDENT FREQUENCY STRETCHES OF HIGHWAY, (7) DATA ON VEHICLE AND PEDESTRIAN VOLUMES TO DETERMINE NEEDS FOR SIDEWALKS, (8) GRADE CROSSING SURVEY DATA TO ESTABLISH PRIORITY IN FORMULATING GRADE CROSSING ELIMINATION OR PROTECTION PROGRAMS, (9) BRIDGE INVENTORY DATA TO GOVERN THE ERECTION OF ALL CLEARANCE SIGNS AND MARKING, (10) INVENTORY DATA TO BE USED IN CONNECTION WITH THE ROUTING AND ISSUANCE OF SPECIAL TRIP PERMITS FOR OVERWEIGHT VEHICLES, AND OVERSIZE VEHICLES, (11) VOLUME DATA TO BE USED IN ESTABLISHING PRIORITY OF CONSTRUCTION AND RECONSTRUCTION OF STATE HIGHWAYS, AND (12) ACCIDENT DATA TO BE USED IN DESIGNING SPECIAL TREATMENT FOR ACCIDENT PRONE LOCATIONS. THIS ILLUSTRATES THAT PLANNING SURVEY DATA IS USED IN THE WHOLE FIELD OF HIGHWAY ADMINISTRATION FROM WHICH HIGHWAY SAFETY IS INSEPARABLE.
