This paper describes the planning, design, construction and initial outcomes of the Auckland ramp signaling project. This project, currently being undertaken by NZ Transport Agency, is aimed at enabling real time management of the entire Auckland motorway network. The planning and delivery of this project is a major undertaking across all 190km of the motorway network, and involves installation of signals on all motorway on-ramps together with a full communications system supporting the associated extensive signage, detectors, cameras, and traveler information systems. Where needed, the project also includes geometric changes to motorway on-ramps to achievethe required operational storage and acceleration tapers. Priority bypasslanes are provided at selected sites to encourage increased vehicle occupancy and where truck and public transport volumes are high. A number of off-ramps are also being improved to match the expected increases in throughput.
