The point-to-point safety cameras are located between Port Wakefield Road and Gawler Bypass
The Northern Expressway point-to-point safety cameras have been activated today following days of extensive testing.
The cameras calculate the average speed of a vehicle between the cameras, as well as the vehicle’s actual speed at each camera location.
The Department of Planning Transport and Infrastructure (DPTI) states that results of surveys conducted in 2015 show that there was an average of approximately 2,900 vehicles per week exceeding 120 km/h on the Northern Expressway.
“We know, as speed increases, drivers have less time to react while requiring a greater distance to stop,” DPTI GM of safety Julie Holmes says.
“The risk of a casualty crash approximately doubles with each 10 km/hr increase in speed on 110 km/hr roads.
“Since the Northern Expressway opened in 2010 until the end of 2015, there have been 63 crashes resulting in one fatality, five serious injuries and 20 minor injuries.
“Speeding and inappropriate travel speeds has been identified as a contributing factor in an estimated 30 per cent of fatal crashes on South Australia’s roads each year,” Holmes says.
The cameras are located between Port Wakefield Road and Gawler Bypass and monitor a 16.6 km section of road that carries an average of up to 23,000 vehicles per day.
Point-to-point safety cameras also currently operate on the Dukes Highway, Port Wakefield Road, Victor Harbor Road, Sturt Highway and South Eastern Freeway.
