New Zealand State Highway Advanced Traffic Management System
Owner: NZ Transport Agency
Location: Auckland & Wellington, New Zealand

Transdyn was awarded a professional services contract by NZ Transport Agency (NZTA) to design, build, and support a new advanced Traffic Management Software (TMS) System to manage the entire New Zealand state highway network.

Running on Transdyn’s DYNAC® ES software, the new TMS system provides NZTA with the flexibility to manage roadway, bridge and tunnel operations from both traffic operations centers located in Auckland and Wellington, New Zealand.

The seamlessly integrated management of traffic and weather systems, electronic message signs, lane control signals, moveable lane barrier, tunnel systems, and traveler information services along with traffic and roadway condition monitoring, incident response, and sign control enhances NZTA’s ability to respond safely and effectively to traffic incidents and emergency situations.

DYNAC® facilitates the sharing of traffic data throughout the state highway network. Information such as traffic data, dynamic sign messages, and incident data is delivered to NZTA’s Traffic Data Repository (TDR) and is used to alert motorists of travel situations in other areas of the country. DYNAC® also disseminates variable message sign alerts to the NZTA Auckland traffic flow website.

A reversible lane configuration on the 8-lane Auckland Harbour Bridge eases congestion at peak travel times. A moveable barrier increases the number of available lanes and maximizes bridge capacity during peak travel times. DYNAC® allows control of the moveable barriers configuration, enabling designated lanes to move traffic in the opposite direction.

DYNAC® will also ease congestion and enable safer travel in key tunnels including the Terrace and Mount Victoria Tunnels in Wellington and Victoria Park Tunnel currently being constructed in Auckland. Located in Christchurch, the Lyttelton Tunnel is the longest tunnel in the country and is being managed by a separate DYNAC® system solely dedicated to the tunnel’s safety systems.

Among the 4 tunnels, DYNAC® will enable management of systems such as lighting, ventilation, fire suppression, CCTV, water deluge, incident detection, emergency phone, traffic signals, dynamic message signs, roadway barriers, and over-height vehicle detection, all from a unified user interface.

Future system enhancements to be provided by Transdyn include nationwide GIS deployment, an interface to New Zealand’s National METS weather service, and integration of Info Connect 2, NZTA’s real-time sharing feed of sign and incident data.
