Dynamic lane control trial begins for morning peak traffic

AM trial starts at 6am, Wednesday 18 April

The morning part of Whangaparaoa Road’s dynamic lane control trial will commence at 6.00am next Wednesday 18 April. Taking on board feedback from the community and considering available traffic flow data, Auckland Transport (AT) is running the trial from 6am to 9am instead of starting at 6.30 as originally planned.

The dynamic lane concept, similar to tidal flow lanes, uses the existing road more efficiently for motorists. It is an innovative solution using traffic control devices and an adaptive LED light system, instead of traditional painted on road-markings. LED lights act as road markings which can change configuration quickly and safely, creating an extra lane during peak hour traffic. Traffic control gantries clearly display which lanes motorists are to use.

The trial has already shown an improvement to PM peak traffic flow. Travel times have been reduced and there is less queuing on the Hibiscus Coast Highway, which has a positive impact on traffic flow heading towards Orewa.

Randhir Karma, Group Manager Network Management and Safety at Auckland Transport says he’s pleased with how the afternoon peak has operated.

“The launch of the morning peak dynamic lanes should help ease congestion between Whangaparaoa and the city centre. Although we do expect for there to be some improvement in the morning we don’t expect it to be as effective as the afternoon peak due to the volume of vehicles merging into the left turn lane at the Hibiscus Coast Highway.”

The Hibiscus Coast Highway intersection will allow two lanes of traffic to be able to turn towards the city centre. Cars will be able to turn left at the intersection as well as using the existing slip lane. Large vehicles such as trucks and buses are restricted to using only the slip lane.

Since the start of the trial, there have been calls to extend the trial to the morning peak. “We were just as eager as road users to make use of the whole dynamic lane control system, but it was important to make sure the system was safe and efficient before the extension,” says Mr Karma.

Once the trial has been successfully completed, Auckland Transport will continue operating dynamic lanes on Whangaparaoa Road, and look into using in other parts of Auckland.
