In Ottawa, compliance with speed limits rose from from 16 per cent before speed cameras to 57 per cent after only three months, and to more than 80 per cent after three years. Instances of speeding at more than 15 km/h above the posted limit dropped from 14 per cent, pre-speed cameras, to less than one per cent after three years of the city using them.
A survey of more than 1,000 Ottawa residents, meanwhile, determined that of the 35 per cent of respondents who had been dinged with an speed camera fine, 69 per cent said it changed their driving behaviour. That’s what we want from these cameras.
A study conducted by SickKids hospital in Toronto and published in July in the British Medical Journal’s Injury Prevention journal found that the use of speed cameras in school zones led to a 45 per cent reduction in speeding motorists, while the 85th percentile speed — the speed at or below which 85 per cent of the drivers travelled — dropped by almost 11 km/h. “The observed reduction in speed is likely important in reducing collisions and injuries,” the study noted
