Help needed to manage average speed trapping data with a view to mitigating Wildlife Vehicle Collisions
With a view to mitigating WildlifeVehicle collisions are working on collecting speed data using Average speed trapping over set distances. We are collecting these data manually that for now is fine, but is there a group member that could point us to )help us with ;-)) a DB system from either two tablets or PC's that will automatically connect the same number plate immediately it is detected for the second time so with a given distance the speed spits out .

Hi Gregory.
I don't know if it's ethical to record license plate pictures for speed detection. It also sounds like it's a bit of a difficult approach to speed detection. Have you considered using a doppler radar based speed detector? You would likely need to DIY it or collaborate with someone that could assist with designing one but I think you'd get more reliable data in an automated way.
Just my $0.02.

Hi Gregory, I agree with Akiba - it can be tricky to get ethics approvals for this sort of thing. I've been working on a wildlife warning road signage project for a few years and the project uses radar-enabled signs to take a speed before and after the sign. Problem is, the signs are expensive. However, we are interested in adding some 'control' or nil-treatment roads to the mix, so we'd be interested in finding a radar speed logging system that we could deploy to mimic the sign radars, along the lines of what @Freaklabs mentioned. A variation on this project perhaps?

Low Cost Radar Speed Sign
Low Cost Radar Speed Sign: Have you ever wanted to build your own low-cost radar speed sign? I live on a street where cars drive too fast, and I worry about the safety of my kids. I thought it would be much safer if I could install a radar speed sign of my own that displays…

Could be worth investigating? This model seems to have reasonable range:

OPS243-C FMCW and Doppler Radar Sensor
OPS243-C FMCW and Doppler Radar Sensor The OPS243-C provides a simple radar sensor solution that can quickly and easily detect and report motion, speed, direction, and range for objects in its field of view. A simple API enables a flexible solution that can be tailored for different applications. Full FCC/IC modular certification (pending) lowers development cost and time.

The other thing that comes to mind is the so-called licence plate camera from Reconyx:
They are limited to vehicles travelling 80km/hr or slower and I think they only take stills, but you possibly use them in multiple places to record plate data.
How are you measuring speed with cameras by the way? Be very interested to hear more and keen to collaborate on a low(ish) cost radar solution if that's of interest.
Cheers,

We are at a PROOF OF CONCEPT with raspberry pi and python and are hoping this can be taken forward. See link below.
