According to Johannesburg Road Agency (JRA), traffic cable faults have reduced from 185 in November 2016 to 147 in September 2017, a notable reduction of 20%.
“Since the inception of the No-Joints Policy in March, the JRA has successfully re-cabled 30 intersections as part of a systemic rollout of recabling at 200 intersections,” said JRA in a written statement. “Re-cabling aims to progressively reduce high incidence of signal downtime at the most critical high-volume intersections city wide.”
Member of the Mayoral Committee for Transport, Councillor Nonhlanhla Makhuba added, “The JRA has made great strides identifying key intersections which are major contributors to congestion across the city. Following the Executive Mayor’s launch of the No Joints policy, the City has invested R45 million Capex budget as part of the 2017/2018 implementation programme which will see the recabling of 200 priority intersections.”
According to the JRA, the roll out involves the removal of old and damaged joints that give rise to repeated faults, most prevalent during rain.
JRA has also implemented a Smart Traffic System which includes remote monitoring of the traffic signals to ensure that faults are detected and immediately, technicians dispatched and repairs carried out. Since the implementation of the Smart Traffic System, 75% of faults have been detected by remote monitoring system and proactive maintenance by JRA technicians. The turnaround time per fault repair by JRA technicians is at present at 21 hours.
As part of JRA’s proactive engagements, 427 Uninterrupted Power Supply (UPS) units have been installed across the city to provide power to intersections during outages, allowing Eskom and City Power to address faults within 24 hours. This has reduced traffic signal outages, congestion and has improved motorist safety.
The project will see the recabling of 40 intersections between July 2017 – June 2018.
