According to the Arrive Alive Campaign, many South Africans do not view obeying the speed limits as an effecive or even important way to avoid road accidents yet, each day numbers of lives are taken unnecessarily due to speeding. The South African traffic department has implemented various speed management systems to try and reduce speeding in the country.

The technology used to manage speed include various tupes of speed trap and camera technologies. When it comes to speed trapping, where vehicle speeds are measured and motorists are pulled over where they are issued with a fine, the following technologies are used:

Laser Speed Gun – also know as a LiDAR speed gun. This device is used to measure vehicle speed and is most often used by traffic officials to measure the speed of a specific vehicle within a stream of traffic.

3D Tracking radar – Similar in technology to the systems used in air traffic control radars, this device tracks the distance, speed and angle of a vehicleand and has the ability to track multiple vehicles and lanes simultaneously.

When it comes to cameras used to measure speed in the case where a motorist is sent a fine for speeding through the post, there are a few categories which these cameras fall into being:

  1. Fixed speed cameras that are mounted at specific locations.
  2. Fixed combined-speed and red-ligh violation cameras These cameras are also fixed to a specific location however, they add the extra functionality of being able to detect when a vehicle has run a red light and whether the vehicle has been speeding, simultaneously.
  3. Mobile speed cameras that are fixed to a vehicle that is parked on the side of the road to monitor the speed of traffic that passes by
  4. Semi-fixed speed cameras are cameras that are fixed in a specific location however, they can be moved if at all necessary
  5. Portable Speed Cameras are cameras set up on a tripod on the side of the road and managed by a traffic official
  6. Average Speed Over Distance Cameras – this system has a camera at the start of a specific stretch of road and then another camera at the end of section. This system relies on number plate verification and calculates the average speed between the start and end of the section to detect whether a specific vehicle has been speeding or not.
