Workers building the chicanes downed tools due to speeding traffic

The sign, activated by passing vehicles, is to go on trial at the A4095 at Bampton, Oxfordshire, to see if it works better than new chicanes.

Work to finish installing the chicanes was being temporarily suspended until the trial is finished.

A survey will then be carried out to find out how well each scheme worked.

Some other people in Bampton did not see chicanes as the ideal solution Councillor David Robertson

Speeding drivers are such a problem in Bampton that workmen building the chicanes downed tools in May because they said aggressive motorists put them at risk.

They claimed a number of speeding drivers narrowly missed them.

Councillor David Robertson, the county council's cabinet member for transport, said: "We are determined to get this right and provide Bampton with the best solution.

"We had discussed the chicane option at length with the parish council and obtained its agreement. Some other people in Bampton did not see chicanes as the ideal solution however.

"This new idea also needs to be tested. If it proves to be more effective than chicanes we will speak further to the parish council.

"The county council has no views either way on which will be the most effective. The trial will tell us that."
