1.5 Determine the equivalent vehicle units (E.V.U.s) for a 2 lane road over a rolling terrain if an annual average daily traffic (A.A.D.T.) of 1300 vehicles was counted with 9% of the total count being heavy vehicles. Because of a proposed upgrading for this road a 10% increase in the A.A.D.T. was predicted with an increase to 15% in the heavy vehicles. What would the predicted E.V.U. rating then be?
