Ramp signalling

Ramp signals will be operating on the Northern Motorway from July. The first ramp signals will start operating on the northbound on-ramps at Tristram Avenue and Upper Harbour Highway. A bus priority lane will also begin operating at Upper Harbour Highway for use by buses travelling north from the Constellation Bus Station. A second group of ramp signals at Esmonde Road (from Akoranga Drive), Esmonde Road (from Takapuna) and Northcote Road on-ramps will also start operating in August.

The signals in the southbound direction will be starting progressively from September. The signals are from Oteha Valley Road to Esmonde Road. Managed priority lanes for trucks, buses and car-pool vehicles (two or more people per vehicle) will also operate at the Greville Road and Constellation Drive on-ramps.

Ramp signalling is an internationally proven traffic management tool used with great success in the United States, United Kingdom, Europe and Australian cities such as Melbourne and Sydney.

Ramp signalling is used to reduce congestion and improve traffic flows and results in:

  • More consistent and predictable travel times
  • Safer merging
  • Fewer accidents
  • Better throughput of vehicles on the motorway
  • More consistent speeds

The systems together with additional cameras, driver information signs and electronic loops in the road are being installed progressively throughout all Auckland motorways to help improve safety and efficiency for motorists.

The New Zealand Transport Agency is installing ramp signals at 31 on-ramps on the Southern Motorway, 15 on the Northwestern Motorway and 15 on the Northern Motorway. The signals are scheduled to be operating across all three motorways by the middle of 2009. Another 14 are planned for the Western Ring Route between Manukau and Albany as it is being built.
