People in two Oxford streets want speed humps outside their homes to be removed because they believe the traffic-calming measures are damaging the building foundations.

People living in Florence Park Road and Cornwallis Road at Cowley are urging highways officers to remove the humps and replace them with alternative safety measures.

A petition signed by more than 40 residents demanding the change is being presented to the city council's highways and traffic committee on Thursday.

But councillors are being advised that tests carried out by the Transport Research Laboratory show there is no risk to properties as a result of traffic vibrations.

The petition, presented by Elaine Aubain, of Florence Park Road, says: "We suspect that the strong vibrations felt at every passage cause damage to the foundations of our houses, and urge you to remove the humps and replace them with central cushions, speed cameras, or textured strips.

"The present humps are higher than the new ones, we have been told, and do not stop anyone speeding, even if they damage the speeding cars.

"The residents would appreciate a quick response and immediate measures taken to stop any further damage, and to make the local bus rides more comfortable."

Gabriel Stocks, senior engineering technician at the city council, has written to Ms Aubain to say there was no evidence that the round-top road humps were damaging foundations.

He added: "Traffic volumes and speed surveys conducted in Florence Park Road reveal that traffic speeds have fallen on average by 6.5 miles per hour, to an average of approximately 24 miles per hour."

The number of accidents has also fallen, from five in five years to three in eight years.

*Residents living in nearby Littlehay Road are requesting road humps to slow buses, which they say are making their homes shake.
