It's funny that this is released the same day as a 56 minute overhead drone video of the Swindon magic roundabout, one of the UK's most iconic road junctions: https://youtu.be/CzQunCuQCJY?si=X1nbcxiWOCcnm8eO

An interesting effect of counting at roundabouts is that MHT/basic inertial movement models tend to work quite well, because the vehicles aren't stopping and starting, and they tend to not bunch up as much as at a red light

Just tossed it over to my GIS and metro-planning friends and they all reacted with "O-hoooo, what a good news" . Kudos!

Excellent, I'm going to post links to installers to make it somewhat more convenient, just haven't gotten to that yet

Seems to be made for USA as only cars are counted. In Europe u usually want to distinguish between cars bigger cars, bicycles and pedestrians. You also need to blurr everything not related to cars and you can't just collect all video data in a central space. Or need lower res cameras.

I made an Android app in this space a few years back. It's helped a few people but I never got a grip on the market or understanding of the space. www.roadcount.com

Looks like it might be using background subtraction, is that right?

Its running EfficientDet on the phone using Tensorflow light.
