I appreciate your comment, but disagree with some of your stats/facts.

Revenue from traffic cameras goes to mostly the police, not for making roads safer. Revenue from all of Ontario goes to the City not the police. A quick scan of a few municipalities FAQ indicates the same. Brampton, [Barrie](https://www.barrie.ca/services-payments/transportation-parking/traffic-control/speed-limits-enforcement. That funding is actually used to implement other traffic calming measures to further help reduce accidents and speeding.

As far as safety goes, the data I’ve seen shows they initially work, then only for about 100m. Red light cameras are the same, they create rear end collisions due to unsafe breaking from someone who should have used the orange light, but was afraid of a ticket.

Barrie's data indicates otherwise, showing a tick up in speed after ASE is removed, but still below the pre-ASE speeds. . I can't find the staff report detailing exactly what their survey data was, but thats still a serious reduction - generally enough to get us almost to the 45% survival rate.

CAA's data shows that driver behaviour IS changing, which is good news and provides hope that this might actually improve behaviour.

If you have any other recent data that shows otherwise, I'd be interested in seeing it - everything I've seen and was taught in school is that speeding is a behavioural habit, and ticketing/consequences are the easiest method to change that habit. It takes time, but habits can change.
