Average speed cameras – do you know how they work?

Average speed cameras – do you know how they work?

  • 29 January , 2019

Have you ever received a speeding ticket and wondered how the average speed camera works? Sure – it can be frustrating to receive a ticket with most modern cars capable of easily creeping above the speed limit without one noticing.

 Average speed cameras have been introduced to counter the driver who slows down for a fixed camera and speed up once out of range.

So how do they work? Linked average speed cameras work by measuring the amount of time it takes to travel between two points – and then calculates the average speed. If your average speed is higher than the posted speed limit, then you will be fined.

The set distance between the linked average speed cameras, according to the authorities, is the minimum ‘practicable’ distance to ensure there isn’t an overestimation of speed – with the stretch of road being assessed by a land surveyor.

In Australia, the type of camera type is called a SPECS camera, or Speed Checks Services. SPECS cameras are always set up as a pair – both cameras are capable of recognising the vehicles’ number plate, through the use of ANPR (Automatic Numberplate Recognition) as well as capturing an image of the vehicle.
