The winning entry in “The Fun Theory” contest is a traffic camera that instead of just ticketing speeders, it also enters people who drive the speed limit into a lottery. Randomly selected winners get paid out of a portion of the tickets paid by the scofflaws.
Before they put in the camera, the average speed was 32 km/h. After, it was 25, a 22% reduction.
It’s a neat idea. I’d also like to see it compared to the before and after on an intersection where they just put in the punitive speed camera, though. Not to mention some of the slowing down might just have been due to people wondering what this device they hadn’t seen before was doing on the streets.
What do you think, would this work in the real world?
