What are you working on? Any new ideas that you're thinking about?

I live next to a school, so there's a low speed limit (30 km/h). Still, people drive like race drivers and the city hasn't ever responded to the residents' hopes of introducing a speed camera.

I wanted to have some data on how many people speed, the max speed recorded, that sort of thing. Things the city should be doing after many complaints of dangerous driving and people being almost killed on zebra crossings.

I have a doorbell camera, and by analysing the footage using OpenCV and some code, I can track how fast people drive if you see how fast they move between two known points.

Average speed: 46 km/h :(

Has anyone been hit by a car there ever?

I think people used to use science to set speed limits.

They did, 30 km/h is a lot safer than higher speeds. You seem to imply someone has to be hit by a car before enforcing the speed limit, am I correct?

No, just implying that when someone is hit that the posted limit has more scrutiny.
