Read before the Society, 31 March 1967 This paper describes a Sample Survey of Road Freight Transport which was carried out by the Central Statistics Office during 1964. The main objective of the survey was to provide estimates, at the national level, of such important economic indicators as the total tonnage of goods moved by road, the ton-mileage performed, vehicle miles travelled, etc. It was also the intention of course, from the outset, to provide the information in considerable detail, e.g. by unladen weight of vehicle, by region, by length of haul, etc. The absence of information of this kind has long been a major gap in the national statistics.
