Children are fully supervised in a walking bus

Officials say the effort to get children to walk to school in the county is "successful and ongoing".

To mark the occasion, a new "walking bus" was launched at St. Bartholomew's Primary School in Wootton Bassett.

They provide families with a safe and practical way of allowing children to walk to school, rather than be driven in cars.

'Improve safety'

Adults supervise the group, which like a bus, has stopping points on the way to school.

A spokesman for Wiltshire County Council told BBC News Online that the adult supervisors involved are fully trained, and that all routes are risk assessed.

"The day was a success and is part of an ongoing effort," he added.

Olivia Thomas, whose six-year-old son walked with the St Bartholomew's bus, added: "We hope that it will help to reduce traffic and improve safety for the children at the school."

Walk to School Week continues until Friday.
