Stop Sign Detector

So there's this Stop Sign

Everyone Runs this Sign

My house has a good view of it from the back...

But of course, I can't spend time counting cars... But a webcam attached to a Raspberry Pi sure can

But I *can* get my housemate to drive his car around the block until I detect it

And then I can really smooth out my object detector code until I get crisp cars every time...

...and *then* I can capture summary statistics about the motion of objects to determine likely violations, like driving backwards

📊 Stats (I moved so results are now static)⏱️

Total hourly stop sign runs

Total daily stop sign runs (Note that these totals result in separate totals due to the difference in resolution of hourly vs. daily)

3,354 Total scans, 10,024 total suspected cases 207+ Hours collected, spanning 53 days

≈6,360 total cars seen, ≈4,223 seen long enough to measure. An estimated ≈39,569 cars have passed the sign, with an average of ≈736 per day.

Machine learning on stop violations is still pending - too few actual stops to accurately assess. As of now, 90.27% of all stops are violations according to human assessment, leading to an estimated 5,741 observed violations, with an estimated ≈35,719 total stop sign runs since monitoring began.
