WORK TRIP DISTRIBUTION AND MODAL SPLIT IN THE METROPOLITAN TORONTO AREA

The purpose of the research project described in this thesis was to formulate and test refinements to existing gravity trip distribution and post-distribution modal split models in order to overcome the serious deficiencies of existing models. These deficiencies arise from: (a) operation of the models at the aggregate or total person trip level; (b) the use of travel time factor function calibrated to base year conditions in the distribution of horizon year trips; and (c) the dependence of modal split models on forecasts of relatively detailed socio-economic data. A unified trip distribution model is proposed in the thesis. The model is based on two groups of trip-makers which are labelled as captive and non-captive trip-makers. The model incorporates a function which allows journey to work trip ends to be split into the two groups from a knowledge of employment and dwelling unit opportunities. A second feature of the proposed model is the direct estimation of the travel time factor function removing the need for the iterative feature of the existing model calibration procedure. The model also incorporates a feature which allows future travel time factor functions to be estimated from a fairly superficial knowledge of future land use and transportation characteristics. /RTAC/
