But did Toronto and Ottawa have to develop a lottery system to enforce the new systems due to capacity issues? Over the course of a month, it was over 400k infractions captured... 40MPH road.

The only reason for the speed to trend downwards is the increasing threat of a ticket from an automated system that cannot be reasoned with. A real cop generally isn't going to ticket me for going 5, maybe even 10 over a posted 40MPH zone unless they fished me for something else during the the stop. Flow of traffic is everything.

Almost all of the cameras were in front of school zones. 10 mph over in a school zone would definitely result in a ticket here. 5mph likely wouldn't, but the speed cameras didn't issue for 5 over either.

The cameras in Ontario issued an order of magnitude fewer tickets than yours. The highest volume cameras issued about 100 a day.

Yeah, 10mph over in a school zone is absurd. The issue I'm referring to are literally TWO speed cameras on common city corridors, non school zones.

The lottery system they're building to support the capacity issue is going to calculate weights based on the most egregious speeders, which I guess is nice...

What also works without needing a huge bureaucracy and fining people regularly is electronic speed detectors that display your speed and flash at you when you're going above the speed limit.

We've got those everywhere. Everybody ignores them. They're probably one of those many things that work while they're new, but stop working after people acclimatize.

They work on me and drivers around me. I regularly see people dropping their speed and being more mindful on roads with them.

The trick is to occasionally (on an unpredictable schedule) put a police cruiser in the same vicinity if the average speed creeps up too much. This turns the readout into a legitimate warning. When you put them out without enforcement then everyone learns to ignore them.

Police regularly giving speeding tickets lowers road speeds. If the police regularly hang out at speed indicators, then people will learn that and only slow down at the indicators. OTOH, with regular enforcement and without the speed indicators people will slow down everywhere. I'd rather have people slow down everywhere.
