The ramp metering system along the N1 between Johannesburg and Pretoria adds an unnecessary cost burden on individual drivers and is ineffective, said the Automobile Association yesterday.
AA Director of Public Affairs Ayanda Vilakazi said drivers joining the N1 found themselves trapped by this system and forced into an unnecessary costly stop and start.
"This inconveniences drivers and is very costly. It subjects drivers to stopping and starting which consumes petrol, delays them on individual businesses and puts pressure on the roads joining the N1," Vilakazi said.
The ramp metering system entails robots on some onramps on to the N1 between Johannesburg and Pretoria.
It is the brainchild of the provincial and national departments of transport.
On Monday, Transport Minister Jeff Radebe said the system had been tried and tested internationally and it was anticipated that it would improve travel times and optimise traffic flow. - Sapa
