Auckland Transport

An innovative way to deal with traffic flows

Whangaparaoa Lane ChangesAuckland Transport will conduct a live trial of an innovative Dynamic Lane Control system on Whangaparaoa Road.

Dynamic Lane Control, uses the existing road more efficiently for moving people and goods. It is a travel solution which makes use of Traffic Control Devices and an adaptive LED light system instead of traditional painted on-road markings.

LED lights show road markings that can change configuration quickly and safely, creating an extra lane during peak hour traffic. Traffic control gantries will clearly display which lanes motorist are to use.

Around the world different kinds of Dynamic Lane Controls have been used to get traffic moving at peak times. In Auckland similar arrangements operate on the Panmure Bridge and Auckland Harbour Bridge.

Dynamic lanes are relatively quick to build and cost effective compared to road widening. They allow for the better use of existing road space, accommodate peak period movements and reduce the need to widen roads or build new roads.

AT has been investigating the concept of dynamic lanes on road corridors since 2014. Following a driver behaviour study conducted with the University of Waikato, AT is now aiming to do a full scale trial in the second half of this year.

Whangaparaoa Road, between Hibiscus Coast Highway and Red Beach Road has been selected for the trial, as the road has two lanes with a wide central flush median equivalent to a third lane. This stretch of road has pronounced tidal traffic movements during weekday peak periods. The installation of dynamic lane controls along Whangaparaoa Road would also require relatively low use of surrounding land, which will minimise disruption to residents.

Andrew Allen, Auckland Transport General Manager of Transport Services says “We are currently finalising our investigation and design of an appropriate system to be tested on Whangaparaoa Road. Rest assured that the safety and convenience of the local community will be a key priority for this trial and affected members of the community will be consulted with.”

The results of the trial will determine the suitability and best approach to potentially introducing the controls along Whangaparaoa Road as a permanent feature as well as its suitability in other parts of Auckland.
