Modelling

The Authority maintains a transport model to support its transport planning remit within the GDA. The model is a strategic multi-modal, network based transport model covering the GDA and Co. Louth. The model includes all the main surface modes of travel (including travel by car, bus, rail, heavy goods vehicles, walking and cycling). Currently, the model covers the morning peak period (07:00 to 10:00) and a single afternoon off-peak hour (14:00 to 15:00).

Guide to the GDA Model

A full description of the current GDA Transport Model – including details of how it was used in the development of the GDA Transport Strategy is available for download: Transport Modelling Report, Greater Dublin Area

The GDA model is available for use by any agency wishing to test the impacts of transport infrastructure or major land use schemes within the modelled area. Any agency wishing to gain access to the GDA model should contact:

The National Transport Authority is currently preparing a set of guidelines for the use of the GDA model and will publish these on this web page in 2012.
