Table F. — The Relation between Summer and Winter Traffic.

Fig. 6. —Comparison of Volumes of Summer and Winter Traffic on an Average Mile of Highway, showing the Distribution throughout an Average Day.

Abnormal peaks of traffic occur on various occasions due to special local events and holidays. This is exemplified by a tally taken at a station between Lower Hutt and Upper Hutt on the WellingtonNapier Main Highway. The average daily volume at this station throughout the year was found to be 1,167 vehicles, private cars numbering|B77 ; but on one particular day during the summer census, which happened to be race day at Trentham, the traffic amounted to 3,398 motor-vehicles, of which 2,900 were private cars or taxis.
