As the keeper of New Zealand’s transportation infrastructure, the New Zealand Transport Agency’s (NZTA) mission is two-fold: to help New Zealanders travel reliably and safely and to grow the country’s economy by investing in moving people and freight. To accomplish these goals, the agency plans and delivers national transport networks; supports local networks; works to make public transport and freight networks more effective; and initiates and invests in projects that improve road safety. Prior to 2009, the NZTA faced a specific challenge: reducing the traffic congestion that was causing high numbers of rear-end crashes and morning/evening crashes on Auckland’s motorways.
The NCTA initiated the project with the objectives of improving traffic flow and safety on the motorways; enabling more consistent speeds for merging; and providing more predictable travel times. In addition, because the project had to be implemented across a large number of sites on Auckland’s motorways, elements of the project had to be incorporated into other NZTA capital projects. This meant the project team had to factor in a number of changes to the scope of work – a daunting task for large infrastructure projects involving specialised disciplines of construction and engineering.
