That said, it may still be stretching it slightly to suggest that those measures, coupled with better targeting of specific risk areas, are enough to account entirely for the jump. Ms Rose also points out that many tickets did not cover the administrative costs of issuing the fines, a valid riposte to accusations of a revenue-gathering motive.
But those claims might be mitigated, to some extent, were the police to adopt the suggestion put forward by AA road safety spokesman Mike Noon, who advocates painting fixed cameras brightly and signposting the areas where they are operating.
By making it clear that a speed camera was operating nearby, drivers would slow down, and surely that's the point - improving driver behaviour.
Removing the suggestion that our country's speed cameras are hidden in the back of unmarked vehicles and tucked away covertly on the roadside would also serve to help counter the suggestion that their purpose is to "catch" motorists. But most importantly, our annual road toll is dropping.
The drop cannot be attributed to one sole factor, and certainly not to the presence of speed cameras alone.
But there can be little doubt that the speed cameras, coupled with increased police vigilance over speeding motorists, is making a positive difference. That's what should matter.
