Fixed-speed and red-light cameras across the UK city of Bristol will be switched back on in the new year in an effort to increase road safety.

The cameras were turned off in 2011 after the government ended the Safety Camera Partnership.

Under the new plan, work will commence in January or February to upgrade and switch on 26 of the 37 cameras in the city roads.

"There are still too many incidents, especially those involving pedestrians and cyclists."

Revenue collected through fines will be used to fund camera maintenance and enforcement.

Mayor George Ferguson will officially announce the decision at a special road safety summit at City Hall.

Ferguson and Police and Crime Commissioner Sue Mountstevens have announced 15 community speed watch schemes, where volunteers are taught to monitor speeds with detection equipment.

Ferguson said: "While the number of those killed or seriously injured on our roads has reduced recently there are still too many incidents, especially those involving pedestrians and cyclists. I have asked officers to start work on preparing speed cameras to be switched back on and boost the number of community speed watch programmes in the city. These measures will boost other efforts to improve the way we all get around the city such as the 20mph zones that are currently being rolled out."

Mountstevens said: "The Mayor and I are both keen to find a way of stopping the war between different road users and find a way of building more tolerance and respect."
