Conference Paper
Full-text available
Peak period crowding in transit networks mirrors peak hour congestion in road networks, particularly in large cities such as Toronto. One of the effective strategies to tackle this problem is time-based transit fares. One potential unintended consequence of implementing such a strategy, however, can be modal shifts from transit to other modes. In o...

The OFF-TET development used a unique joint RP-SP survey of commuting mode choices. The OFFice based Survey for Evaluation Tool development (OFF-SET) was designed considering a suit of TDM policies that are deployable by the employers to manage travel demand of their employees. OFF-SET uses RP travel mode choice information to pivot SP mode choice scenario development by using the state-of-the-art efficient SP design approach. In this study, OFF-SET is implemented for the Region of Peel. A sample of commuters who work in the Peel Region was surveyed and data are used to estimate the discrete choice model for commuting mode choice. The choice model contains variables capturing effects of various TDM policies. Finally, an Excel-based evaluation tool developed that uses the choice model at its core and predict response to implementations of one or multiple TDM policies. The tool is named as OFFice based TDM Evaluation Tool: OFF-TET. OFF-TET can predict changes in modal share for various TDM policy evaluations capturing individual as well as compounded effects.
Project
A Comprehensive Utility maximizing System of Travel Option Modelling (CUSTOM) is under development for Toronto. CUMTOM is fundamentally superior to similar models. Custom is free from the problematic limitations of key components of the activity-based travel demand model that are often defined arbitrarily by someone. Compared to the problematic hard-wired rule based scheduler used in many operational demand modelling system the CUSTOM is theoretically consistent with microeconomic principles and grounded firmly on statistical validity. CUSTOM presents a suit of interconnected sub-models that are based on behavioural theory (combination of human psychology, time geography and microeconomics) of travel demand. Unlike many recent operational Models, CUSTOM provides a flexible platform to accommodate different mode choice modelling approaches that can serve respective purposes of demand model applications.
