Question:
Good day, I travel the M13 from Kloof to Durban on a daily basis. New average speed signs and cameras have been or are in the process of being erected.
Great idea, that road is dangerous. But how does it work? The first stretch is 3.2km at 80km/hour speed limit, the next 1.1km is at 100km/hour.
How are you calculating acceleration, and on what speed will somebody be fined, over 80 or over 100. Sounds like a mathematical puzzle to me.
Answer:
The higher speed limit of 100km/h will be used for prosecution subject to the Director of Public Prosecutions approval. At the moment its being used for statistical purposes until the required authority is given. It must also be noted that the main purpose of the project is oriented at Road Safety. The system identifies:
- Overloading offenders (through dynamic weighing integrated with number plate recognition cameras).
- Trucks over 16T using Fields Hill during restricted time periods
- Outstanding warrants linked to registrations
- Unlicensed vehicles
- Un-Roadworthy vehicles
- Stolen Vehicles
- Average speed enforcement
At this stage we are only focusing on the Eastbound Direction although gantry’s have been installed (without cameras) in the Westbound Direction which will be rolled out at a later stage.
Hope this helps.
