The Radars are in two places as they are the type that use the loop system - you pass one, it counts you in then when you pass the next one it calculates if you got there too quick - then bang they have clocked you speeding,

Locations - one on stretch between Sheraton Roundabout and the turn off for the business district there, second one around the fountain area on the grass.

I think they really need these type of radars on the straight roads eg - sports city road, or some of the 100km roads as people just break before the cameras that are there and are more likely to cause an accident.
