How 400 Cameras Will Put Scotland’s Drivers in Picture
A NETWORK of 400 cameras will supply the journey-time information by recording how fast vehicles travel between two designated points on the motorway network.
These cameras will use automatic number plate recognition technology to track such movements and then calculate average journey times, which are then displayed on electronic roadside signs.
The equipment being used is similar to that used by the police, who operate a separate network of cameras, which are sited across the roads network. They are also fitted to police cars.
The number plate recognition system enables police officers to track criminals.
It is also capable of instantly checking vehicles - at a rate of nearly one every second - to ascertain whether they are being driven without road tax or insurance.
