A new traffic light system to improve peak traffic flow on SH29A at Barkes Corner is now up and running.

The lights have been installed at the roundabout on the Pyes Pa Road and the SH29A westbound approaches to the roundabout.

The lights will be queue activated – a system called roundabout metering.

The Agency's Bay of Plenty Transport System Manager Rob Campbell says the lights are designed for roundabouts where one road is busier than the others leading into the intersection, dominating the flow into the roundabout and causing delays on the other roads.

'The Pyes Pa Road approach to the roundabout is busier than the other roads in the morning peak, so the traffic lights on the SH29A westbound approach will hold back traffic to allow Pyes Pa Road traffic through.

'Similarly, the traffic lights on Pyes Pa Road will be phased to improve the flow for eastbound traffic on SH29A from Tauriko during the weekday evening peak.”

The roundabout traffic lights will be on 24/7 and will be approximately 30m before the give way signs.

'Most of the time the traffic lights will be green, except when high traffic queues on one leg activate them, then the traffic lights will turn red to stop the vehicles, allowing traffic from the busiest road to enter the roundabout. The red phase is short and will turn green before another large queue is created.”

Standard give way rules will still apply when entering the roundabout – even when the traffic lights are green.
