This note gives the results for 1964 of a traffic census which has been in progress, since January, 1956 at 50 points on trunk and classified roads of Great Britain. Motor vehicle mileage on these roads in 1964 is estimated to have been 11 per cent higher than in 1963, 34 per cent higher than in 1960 and 84 per cent higher than in 1956. The increase in motor-vehicle mileage from 1963 to 1964 was 11 percent; but for the cold weather which reduced traffic in the early part of 1963, this increase might have been only about 9 per cent. Mopped mileage rose sharply but the mileage of the other motorcycle classes and of deal cycles continued to decrease. The mileage of licit evans changed little from 1963 to 1964. Tables are given showing month by month variations on different categories of road and on different days of the week, in urban and rural areas, and for different classes of vehicle. Some of these figures are given in index form. Daily motor-vehicle-miles are given for 1964. Year by year estimates are given of the mile ages of various classes of vehicle on all roads except motor ways, based on data obtained from the 1000-point census made in 1960 as well as from the 50.point census. Figures are given for accuracy of the estimated trends of annual and monthly vehicle mileage on trunk and classified roads, The motor-vehicle mileage on all motor ways has been estimated from available count; in 1964 it was bound to be about 2 per cent of that on all other roads,
