This thesis develops the foundation of a model to predict P.M. peak vehicle trips for the Manitoba Capital Region. This model, called the Manitoba Capital Region Transportation Planning Model (MCRTPM), is built on a Geographical Information System for Transportation (GIS-T) platform. Components of the model were calibrated using the 1996 Statistics Canada Journey-to-Work database and the matrix adjustment algorithm with newly developed traffic data from the City of Winnipeg and Manitoba Department of Highways and Government Services (MHGS). The foundation developed in this thesis allows further refinement to be made to the MCRTPM in order to develop a complete model. This model facilitates transportation planning in the Manitoba Capital Region.
