Single System for Active Traffic Management across New Zealand: Implementation and Ongoing Expansion

In 2009 the process for procurement of a replacement active traffic management system (ATMS) for New Zealand‟s largest road controlling authority, the New Zealand Transport Agency (NZTA), was presented at the Stockholm ITS World Congress. Since then, a DYNAC® Enterprise Server system, developed by Transdyn Inc, has been successfully implemented, and NZTA is in the final stages of completing enhancements that have been implemented after the initial rollout took place in 2009-2011. The system, as it is being used in New Zealand, is the new master control system. It is unique in that it is being rolled out as a national system for traffic management on the entire state highway network of a country. This paper provides an overview of the system and its applications, emphasizing the use of a single system to manage traffic across a network and the use of two geographically separate transport operation centres (TOCs) in Auckland and Wellington. It also discusses the challenges experienced so far and the plans for the future of the system, including integration with progressively more systems and subsystems, additional field devices and equipment and newly developed parts of the state highway and motorway networks.
