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 :(

I'm starting to think about a similar thing for noise. The noise of motor vehicles seems to be out of control and I am sure it is causing misery for the majority of the population who have to live near roads. I reckon a single loud motorcycle could disturb tens of thousands of people, potentially waking or startling them, raising blood pressure etc. in a single 10 minute trip. Unfortunately I think awareness of this problem is even worse than speed.

I used to live in a neighborhood about a quarter mile from a highway, nearly perfectly flat land, speed limit I believe was 45 or 55.

Most days the road noise itself was no big deal, if the wind blew it was gone, if you listened for it you could hear a whooshing/droning in the distance.

But all it took was one loud motorcycle or old car/truck to really ruin your peace for a solid 3 to 5 minutes, being able to hear it on approach, and it went by, and exit. And it wasn't that rare to get them back to back, seeing as it's a 4 lane highway with a decent flow of traffic.

It wasn't really until then I realized how a single vehicle could cause so much annoyance for so many people.
