Show HN: Open-sourced (road) traffic counting application
github.comI was developing/selling this application under Roadometry, but sales are getting slow and I'd prefer to make it available for free.
This is a desktop Windows application which can be used for counting road traffic.

The application uses Multiple Hypothesis Tracking (MHT) combined with Darknet Yolo.
I trained the network myself. I have a tool-chain for building a video-based training set including associations, but it's quite complex to use. I never ended up training a network to perform association, but I think a combined detector/associator network is the next step. 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 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. Very cool, thanks for sharing. How did you train it? Just manually labeling the data? I hired some workers in Bangladesh <i>I think a combined detector/associator network is the next step.</i> Repentance for using MHT to accelerate vehicle interconnectedness might consist of V2I. Audi vehicles with 802.11p V2I capabilities have an information sharing agreement with Traffic Technology Services in certain municipalities that alert a driver of a vehicle when a red light will turn green. https://arstechnica.com/cars/2018/03/cars-that-talk-to-traff... 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 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.

Thanks! your github repo link is broken, perhaps you forgot to unprivate it. Whoops, thank you. Fixed now. 404? I accidentally linked the wrong repo (it was original/unredacted with API keys, etc). The correct repo is:
https://github.com/asfarley/vtc_opensource Assume someone grabbed the API keys. Change them as soon as possible. Changed now. Thanks! From the EULA.txt [0]: """
