American-style yellow school buses have dramatically cut traffic, according to their operator.
Yellow buses have reduced traffic in Hebden Bridge
About 1,300 children aged four to 18 have started taking yellow buses to school since the launch of the first service in Hebden Bridge, West Yorkshire, a year ago, the First bus company has said.
Research to be published by the government later this year will show the buses have encouraged people not to use their cars to take children to school.
Children each have a seat assigned to them, are picked up near their homes and drivers are specially trained under the same system that has applied for years across the Atlantic.
First said its buses could cut car journeys in Hebden Bridge by 60,000 a year and by
180,000 in Runnymede, Surrey.
The other areas with US-built yellow bus services are Aberdeen in Scotland, Wokingham and Windsor in Berkshire, and Wrexham, North Wales.
Neil Denham is head of Riverside Junior School in Hebden Bridge, one of the schools using the yellow buses.
He said: "Riverside School is in a busy cul-de-sac in the centre of town so traffic build-up was absolutely horrendous, people were parked up everywhere.
"But with 25 of our children already using this bus we've got rid of at least 13 of those cars - it's been marvellous."
