Transport analytics provides the evidence base to inform transport and land-use decisions, with potentially far reaching and long-lasting implications that affect our environment, the economy, social well-being and urban form.


EMME is a multi-modal transport planning software that is used worldwide. The Wellington Transport Analytics Unit have two models that have been developed in EMME – Wellington Transport Strategy Model (WTSM) and Wellington Public Transport Model (WPTM)

The software combines “off the shelf” functionality with the ability to develop a bespoke 4-stage strategic transport models (trip generation, trip distribution, mode split, assignment) to fit local data sources and analytical requirements.

AIMSUN Next is a multi-resolution modelling platform that simulates mobility in networks of all sizes. The Wellington Transport Analytics Unit operate and maintain AIMSUN models of Wellington City and Hutt City and are about to develop a new model covering Porirua City.

These models focus on representing traffic demand, using the AIMSUN Hybrid structure whereby large areas can be modelled with mesoscopic simulation, together with added levels of detail within areas such as Wellington CBD where microscopic simulation is required.
