Techlink would like to thank the experts at Transit New Zealand, Serco, Tyco and MWH (Montgomery Watson Harza) New Zealand Ltd, for their contributions to this case study.
Introduction
In February 2001 Transit New Zealand began operation of an internationally leading-edge Active Traffic Management System (ATMS) within a 4km section of the Ngauranga Gorge between Johnsonville in Wellington and the SH1 and SH2 interchange.
The Ngauranga ATMS is designed to reduce the number, severity and impact of incidents on this demanding section of highway and improve overall traffic flow (Conceptual statement). This has been achieved through the communication of up-to-the-minute information to road users, emergency services and traffic controllers and implementation of faster, more appropriate traffic and emergency management responses. The system is intended to reduce the number of accidents, driver frustration and delays by creating a safer motorway environment.
Glen Prince senior traffic engineer is a member of the MWH Traffic Design Team who provided traffic engineering and road safety expertise to Transit New Zealand.
