The state of Victoria, Australia will begin using point-to-point fixed speed cameras that average speed over a long distance by the end of the year. The system uses a network of speed cameras that communicate with one another in such a way that even if you pass them driving below the speed limit, you will be ticketed if the system believes you were driving faster than the limit in between them. NSW, Australia uses a similar system called Safe-T-Cam to monitor trucks.The Government, which made almost $170 million from speeding fines last year, has confirmed it has signed the contract for the new point-to-point cameras and they are likely to be spread between Craigieburn and Wodonga.Source: Fines roll in from new speed trap (The Age (Australia), 2/27/2005)
