THE FREQUENCY OF OVERTAKING ON TWO LANE ROADS

THIS DOCUMENT LOOKS AT THE THEORETICAL RELATIONSHIP BETWEEN TRAFFIC VOLUME, SPEED AND FREQUENCY OF OVERTAKING ON TWO LANE ROADS. IT ALSO EXAMINES DATA COLLECTED DURING A FIELD SURVEY AND FROM THESE DEDUCES THE NUMBER OF OVERTAKINGS AT A RANGE OF TRAFFIC VOLUMES AND THE SPEEDS AT WHICH THEY OCCURRED. AFTER INVESTIGATING THE SPEEDS AT WHICH OVERTAKINGS OCCURRED THE REPORT CONCLUDES THAT THE GREATEST NEED, BY FAR, IS FOR FREQUENT PASSING OPPORTUNITIES RELATED TO THE VERY SLOWEST SPEED GROUP AND THAT THIS IS ESPECIALLY SO WHEN A ROAD IS OPERATING AT OR NEAR CAPACITY.
