Tauranga City Council
Tauranga is a small but rapidly growing city situated on the Pacific coast of North Island, New Zealand.
The city’s traffic model belongs to regional stakeholders including New Zealand Transport Agency, Tauranga City Council, Western Bay of Plenty District and Bay of Plenty Regional councils. It was developed by Beca and Aimsun, with Flow Transportation Specialists and Robinson Transportation Consulting providing procurement, project management and peer review.
The previously existing strategic travel demand model is on the Cube Voyager platform, and has been closely coupled with a new hybrid mesoscopic-microscopic supply model in Aimsun Next, which is aimed at addressing operations and design projects.
The entire Tauranga strategic model network and zone system was imported and converted to an Aimsun Next mesoscopic network with demands profiled from 2-hour peak periods into 15-minute time slices. In the CBD as well as greenfield growth areas, microscopic pockets provide a finer level of detail to address questions around actuated signal timing in SCATS, parking garage search and circulation, and active mode interactions.
The original three-step strategic model of Tauranga has effectively been transformed into a very useful multimodal forecasting tool that has the kind of public transport, carpooling (T2, T3), tolling, bicycle and parking pricing policy capabilities that are not usually available to decision makers in a city of this size. The combined model is being used on a variety of projects ranging from bus rapid transit studies through to rural highway and passing lane studies, downtown strategies as well as street-scaping projects.
