MONITRON worked out I was van and did me for 59 in 60 limit

jimbo1

I thought my new van was just classed as a car derivative and was OK at National speed limits.
Just got a ticket from a MONITRON which clocked me at 59 and it worked out that I was a goods vehicle and limited to 50 on single track roads, 60 on dual carriageways and only 70 on motorways.
I have checked the vehicle class/weights etc and found out I was wrong it is a goods vehicle!
Are all speed cameras as intelligent as the MONITRON and can work out vehicle type from the registration number?
I am now looking forward to a flood of tickets as I passed this and other MONITRON cameras religiously at less than 60, 10 MPH too fast.
Oh dear, one learns something every day.

Interesting. There has been much debate on these but nothing concrete as to how they achieve this 'skill'.

If the decision as to what is and is not a Goods Vehicle is based on DVLA data then each camera would need both ANPR and a live link to the DVLA or a regularly updated database in each camera.

Sorry to hear you were nabbed, it does seem a rather odd law when the vehicle is a car derived van but it is more food for thought as to how these cameras function.

They were using Monitrons on the M55 some 3 years ago for speed trap and ANPR, was there a sat dish or microwave link attached near the camera? - see This Thread for more details - Mike

Probably Monitron 30013@60 - Mike

I have seen camera systems coupled to a PC running software called NI IMAQ which is an image processing package, it can check anything from spark plug gaps and accurately measure them to ANPR duties. If this software can do the above its not too difficult to imagine scripting some code to do ANPR and measure the height/ width of a vehicle and only keep the pictures of vehicles that exceed a threshold relative to vehicle speed and size.
As for the speed this system can work at, on a good PC it will easily manage ten checks per second from a single camera so recognising cars/ vans etc even on a busy motorway would be very easy and not require manual post processing to filter the good from the bad - Mike

I am not 100% sure that the NI product range or software is actually deployed in a Speed Camera system but if you have used Labview with the iMAQ plug in combined with a camera then I am sure you will agree to program a system to achieve this sort of capability would be very easy.

Run it on cRIO fitted with a GPRS modem and and you have a headless system that can send pictures back with the speed, date, time and location etc embeded in the picture by internet or e-mail to a central location, all it would need is some relatively low power to run it - Mike

As far as surveillance techniques go, I think it's pretty obvious by now that if the powers-that-be in this country CAN do something , then they WILL do it.
Other European countries wouldn't dare.

Not sure about that surveillance point - this topic seems to be about using technology for detecting the difference between a small and a large vehicle which have different legal speed limits applied - I wouldn't call that surveillance really.
