Show HN: Open-sourced (road) traffic counting application

by asfarley on 12/2/24, 10:53 PM with 24 comments

I 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

    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?

    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.

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

    Kudos!

    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.
