In this article Dr Garwood discusses two main sampling problems arising in road traffic flow statistics. The first is that of the accuracy with which trends from year to year in the total amount of travel on the road can be estimated from continuous counts at a sample of points on the road system. The second is concerned with sampling in time at particular points and the effect of geographical factors on sampling efficiency. One application of this concerns the concept of the economic capacity of the road, the formula for which involves the coefficient of variation of the hourly flows. Values of the latter are given for some typical roads.
