SA ramp metering set to go permanent

Right: Traffic flows on South African highways improved with the introduction of
ramp metering


Ramp metering is expected to become a permanent feature on roads in Gauteng, South Africa, in January.

The South African national roads agency (Sanral) says trials that started in September on the Samrand, New Road and Rooihuiskraal on-ramps on the Ben Schoeman highway have increased freeway flow by approximately 400 vehicles per hour.

“Several other actions are taking place on the freeway network that forms part of Intelligent Transport Systems,” says Sanral spokeswoman Wendy Watson.

“These include the shoulder lane between Allandale and Buccleuch [off-ramps] that increased traffic throughput by 1,700 vehicles per hour. The Gauteng Freeway Improvement Project aims to substantially upgrade the network and interchanges.”
