New speed cameras trap motorists from space
A new type of speed cameras which can use satellites to measure average speed over long distances are being tested in Britain.

Satellites could track motorists from space if trials prove successful Photo: AFP The cameras, which combine number plate reading technology with a global positioning satellite receiver, are similar to those used in roadworks.

The AA said it believed the new system could cover a network of streets as opposed to a straight line, and was “probably geared up to zones in residential areas.”

British steam supercar to challenge world land speed recordThe Home Office is testing the cameras at two sites, one in Southwark, London, and the other A374 between Antony and Torpoint in Cornwall.

The `SpeedSpike’ system, which calculates average speed between any two points in the network, has been developed by PIPS Technology Ltd, an American-owned company with a base in Hampshire.

Details of the trials are contained in a House of Commons report. The company said in its evidence that the cameras enabled "number plate capture in all weather conditions, 24 hours a day". It also referred to the system's "low cost" and ease of installation.

The system could be used for "main road enforcement for congestion reduction and speed enforcement", and could help to "eliminate rat-runs" and cut speeds outside schools, it added. It could also reduce the need for speed humps.

The development of speed cameras has raised concerns about expanding state surveillance.

The Home Office said it was unable to comment on the trials because of "commercial confidentiality".

The AA said it would watch the system “carefully” but it did not believe there was anything sinister. “It is a natural evolution of the technology that is out there,” a spokesman said.

seems that we will be in BIG trouble if this SpeedSpike put into use! But i think it is not possible to monitor every single speeder on earth from the magnitude of computation point of view if you know what i am saying...

i was talking about the complexity of computation... i just wonder if you are in the same industry as i am since you mentioned in another thread that you are in college right now. never mind. :)
