I am still on the trail of system that will help us to slow traffic down. We have incidentally started monitoring speed with a plastic bag marker and stopwatch over distances of 700 metres and have results highlighting the extent of the problem. Some vehicles are doing twice teh speed limit of 80, and whilst we still need an instantaneous speed camera, there is now greater need for someone to help us with basic system so that we can reliably determine average speed over a distance of 70 km. Reliable is key as we are getting closer to having law enforcement agencies assist.
So what do we now need? We envisage a camera that will read the number plate, Record the time, take a picture, and transmit these data via a cell network to enforcement of the other end who will have a similar system to match the plate number and have the average speed calculated.
Any ideas welcome.

I love this user requirement! Is this for a conservation need?
The Instant Detect 2.0 system, when launched later next year, could definitely do part of this job.
If you placed the Instant Detect camera with a metal detecting sensor buried in, or alongside, the road it would reliably trigger and capture a burst of images everytime it detected a vehicle passing by. I have tested the capture up to 60Kmph. the images would then be sent by radio to a Base Station and then over satellite to a cloud based interface.
You would need to have two systems (two base stations) as the radio wouldn't reach 70 Km, placed at either end. Both systems would then feed their images to the same cloud based interface.
The bit that would need extra development would be having a VRN plate recognition algorithm check the images on the interface to match number plates taken by the two cameras and then check the capture time (recorded in the image). But thinking about it, I don't think this would be that hard.
The cameras and base station could be run off solar if you can protect them well enough, so power is unliklely to be an issue. The only thing I can think that might be needed is some process for law enforcement to prove that the times recorded by the cameras are set correctly and identically - the time used is pulled down by satellite from the server so this should always be the same.
Where are you based?
