Average Speed Over Distance System

[Jan Horn]

Unfortunately the google street view photos for this road predates the time of the installation I tried a couple of times using street view to locate the gantries but again I never looked around the border area.
Looking at this report you may very well correct that the gantry is around the border and not as shown on that screen shot I posted

NO FATAL CRASHES
The project was initially implemented in October 2011 on a 71.6km stretch of road between Beaufort West and Aberdeen on the R61 - the longest camera network of its kind in the world.
Transport MEC Robin Carlisle’s office said of the plan: “Prior to the initial implementation on the R61 stretch from Beaufort West to Aberdeen, there had been a reported 509 crashes in total, 75 of which being fatal crashes resulting in the loss of 149 lives - this over the previous 12 years.

mmm....
So the Asods sits between Aberdeen and the provincial border.
But looking at the type of camera used at the time, and the distances apart, (10 km) it was only a project.
Maybe they installed the latest type of cameras by now, or simply removed everything.

.... anybody want's to go for a sunday afternoon drive perhaps?

I think that those are for a project by the Eastern Cape province. The real Asod zone would be on the WC side between Beaufort West and the border. What is weird is there are no signalling infrastructure showing that is required to make a Asod system work. The camera need to send information regarding vehicle identification and time to a central processing sentrum where the average speed is determined.
Next time I go down to Cape Town I will make a short detour at Beaufort W and drive a few km along the R61 to see if I can pick up the first Gantry. I don't know when that will be I have a few issues to sort out first before that happen

The Street View image date for that road reflects as September 2010 and the Asod on the R61 was introduced in October 2011 so it seem that the images we use to try and find the Gantry positions are too old to show them

A big word of thanks to Frans and Phillip for finding these cameras.

[Jan Horn]

I am fairly sure I found the two gantries at S32 21 05.8 E22 36 35.2 and S32 34 43.0 E 23 17 22.0

They are visible in google earth but not in street view because of the time difference between the images.

Jan, you are right with regards to the imagery shown on Google streetview. The only camera position I could pickup from Google Earth, is in the attachment. The streetview imagery on the attachment is dated Sept.2010. Your images shows "white objects", but it's difficult to see what they really are. As, mentioned, the only way to really find the Asod zone cameras on the R61, is to travel the route and plot the real positions. Maybe there might be someone, out there, willing to help with this.

I found this regarding this Asod

That's a positive then!

Thanks to Jan, this topic with regards to the Asod cams on the R61 is finally settled....a job well done.

Regards.

Little bit late, but never the less. I also found the Asod cam positions on the R61 road.

I came across this and thought it would bring this thread yo a nice conclusion. I thought it was an insignificant little road, And imagine averaging 176 km/h over 71.6 km

THERE'S no dodging the long arm of the law on a notorious stretch of tarmac dubbed the "road of death", where technology is forcing humans to behave behind the wheel.
Motorists have, for years, out-witted speed traps by simply slowing down before the device, then accelerating again.
But there is no fooling the world's longest Average Speed Over Distance (Asod) surveillance system in the central Karoo.
Big Brother - in the form of two sophisticated overhead cameras - is mercilessly policing 71.6km of the R61 between Beaufort West and Aberdeen.
The road carries peak holiday traffic between the Eastern and Western Cape and has claimed nearly 150 lives in 12 years. Just under 800 vehicles an hour were passing Beaufort West on Monday.
A 40-year-old Cape Town man earned the dubious honour on Wednesday of being the 10th driver to be arrested on the spot for excessive speeding - defined as 40km/h or more above the 120km/h limit. He drove at an average of 164km/h over the 71km stretch. A 176km/h offender was arrested on Thursday.
