Travel demand models are essential policy analysis and decision-support tools for regional and local transportation planning. This is particularly the case for a large, complex and expanding region such as the Greater Toronto-Hamilton Area (GTHA), which is facing major challenges to develop, implement and operate a multi-modal transportation system for the movement of both goods and people that meets the economic, environmental and social goals of the region in a cost-effective and sustainable manner.

The Travel Modelling Group (TMG) is a research group housed within the Department of Civil Engineering, University of Toronto.

TMG works to eliminate the duplication and fragmentation of effort which often has occurred in the past in model development efforts within the region, and to provide a well-documented foundation within which on-going model development and application work can build.

TMG provides a forum and mechanism for inter-agency collaboration that will lead to improved modelling practice for all.

Current GTHA transportation agency partners in TMG are: Metrolinx, the Ontario Ministry of Transportation, the Cities of Toronto, Hamilton, Mississauga and the Regions of Durham, York, Peel and Halton.
