ADVISORY SPEED SURVEY PROCEDURES

THE SURVEY PROCEDURES AND SIDE FORCE CRITERIA CURRENTLY USED BY AUSTRALIAN STATE ROAD AUTHORITIES FOR ADVISORY SPEED DETERMINATION, ARE DESCRIBED AND COMPARED, TOGETHER WITH A BRIEF DESCRIPTION OF AN INSTRUMENT SYSTEM FOR ADVISORY SPEED SURVEYS CURRENTLY BEING DEVELOPED BY THE AUSTRALIAN ROAD RESEARCH BOARD (ARRB) FOR THE DEPARTMENT OF MAIN ROADS, N.S.W. THE RESULTS OF AN ERROR ANALYSIS ARE PRESENTED, WHICH SHOW THAT THE ERRORS IN COMPUTED ADVISORY SPEED FROM SURVEY INACCURACIES ARE GREATER THAN THE DIFFERENCES WHICH OCCUR DUE TO THE DIFFERENT CRITERIA USED BY THE ROAD AUTHORITIES. MEANS OF IMPROVING THE ACCURACY OF EXISTING SURVEY PROCEDURES ARE RECOMMENDED. IT IS SUGGESTED THAT, IF THESE RECOMMENDATIONS ARE IMPLEMENTED, IT WOULD BE POSSIBLE TO COMMENCE USING A UNIFORM SIDE FORCE CRITERION FOR ALL STATES, WITHOUT RESURVEYING CURVES WITH AN EXISTING POSTED ADVISORY SPEED.
