The number of vehicle kilometres - a measure of the number of trips made - rose from 5bn to 436bn in 1996 and was mostly due to an increase in car journeys.
Between October and December, the number of cars increased by 2 per cent, and light vans by 4 per cent, according to traffic counts. Over the year, cars went up by 1.5 per cent and light vans 1 per cent. Goods vehicle traffic showed no change. The annual increase for motorways and minor roads was 2 per cent, with no growth on trunk and principal roads. Randeep RameshReuse content
