Intelligent Transport System

Transmission Gully uses an Intelligent Transport System (ITS) to provide accurate, real-time incident detection and prompt response. The ITS detects changes in the traffic flow using radars along the motorway. It is the first full coverage radar system to be used to monitor a motorway in New Zealand.

The ITS also incorporates weather and visibility sensors, accelerometers for measuring seismic activity, and 22 CCTV cameras that are monitored by Ventia’s team of motorway operators, who work alongside the Wellington Transport Operations Centre to maintain traffic flow and reducing traffic congestion.  

Incident Response Service

Ventia’s Incident Response Service (IRS) team is responsible for responding to and clearing incidents such as breakdowns and accidents and assists emergency services with the safe and timely management of serious incidents.
