Homemade Speed Trap Made By Former UVA CS Professor (cvilletomorrow.org)

An anonymous reader writes: Irritated by speeders in his neighborhood and frustrated with the City of Charlottesville's inability or unwillingness to enforce the speed limit, a former professor in the Computer Science department of the University of Virginia created a program in openCV to track vehicle speed on his residential neighborhood street: "You'll find that almost 85 percent of the cars going by are violators [of the neighborhood's 25mph limit]". This includes a city bus doing 34mph.

therefore the speed limit is invalid

At least in California, other than the absolute maximum, and things like school zones, roads have to be surveyed periodically, and the speed limits must reflect the prevailing speed. If it is 85% near some higher number, including mass transit, then the limit is too low.

Here is a Raspberry Pi version FYI

Last summer I wrote a python opencv program for a Raspberry Pi computer and Pi camera module. This monitors in real time. It has a lower fps due the hardware capability but does work Ok when calibrated for the distance. Here is my YouTube video https://youtu.be/eRi50BbJUro github repo is here https://github.com/pageauc/mot.... This was just done for fun after reading a forum article on the subject.

Re:legalism is a crap philosophy.

Anyone that speeds in a residential area is the worst type of scumbag.

On an open highway, go for it, I think we should be allowed to go 100mph. Driving around people and kids only a few feet from their homes, they need a punch in the face to go along with the ticket.
