Swindon Borough Council last week announced that it is to stop funding fixed safety cameras, saying that the £320,000 it pays annually towards the cameras would be better spent on warning signs and better lighting.
It is believed to be the first local authority in England to withdraw funding for fixed cameras, which are run by the Wiltshire and Swindon Safety Camera Partnership.
The authority says the number of people killed or seriously injured on Swindon's roads has risen in the last two years and new strategies are needed.
RoSPA said cameras in areas with genuine accident problems are part of a proven package for reducing road casualties. Spokesman Roger Vincent said: "Speed cameras should be used alongside other measures, such as greater police enforcement, if that is the right solution for the area. If changes are made in Swindon the situation needs to be closely monitored to see what lessons can be learned."
