use made of goods vehicles month by month throughout the year?
ASuch figures in respect of 1965 are given in the 50-point traffic census report made recently by the Road Research Laboratory of the Ministry of Transport.
Dealing with goods vehicles (other than light vans not exceeding 30 cwt. unladen), the total estimated mileage on trunk and classified roads in Great Britain for the whole of 1965 was 10,086m. giving a monthly average of 840m. The lowest monthly mileage was 756m. in February while the highest was 897m. in September. But overall the monthly fluctuation for goods vehicles was much less marked than for other categories.
As with all such national averages there is, however, an element of counter-balancing which could apply, in practice, only to the very largest haulage operators. Because haulage is predominantly made up of small units often operating from one base only, the seasonal fluctuation in any one area—whether agricultureor industry-based—would obviously be far more marked than the national averages reveal,
