Speeding drivers take note: the average speed over distance (ASOD) camera network in South Africa is expected to expand in the coming years.
ASOD systems are currently operating in parts of the Free State, KwaZulu-Natal, and the Western Cape, with plans in the pipeline to install more cameras across the country.
The reason for the planned expansion is simple: the ASOD system is effective at reducing speeding.
Arrive Alive’s Johan Jonck said the system is not only “fair”, but it also frees-up traffic officers to attend to other road rule violations.

How the ASOD system works
The fist ASOD systems were used in a pilot project along the N3 in KwaZulu-Natal in 2010, after which they were rolled out to other parts parts of the province.
The Western Cape followed suit, and rolled out its 452km ASOD network to many of the most dangerous stretches of road in the province.
The ASOD system works by taking a photo of a vehicle and its number plate at a start point (point A) along a piece of road, and another photo at the end point of the same stretch of road (point B).
The time it took the vehicle to travel between point A and B is calculated, and if it is faster than the predetermined limit for that section of road, the driver is issued a speeding fine.
