THE ANALYSIS OF TRAVEL AND EMISSION IMPACTS OF TRAVEL DEMAND MANAGEMENT STRATEGIES USING ACTIVITY-BASED MODELS
Current transportation, emissions and air quality methodologies were developed independently from one another and for essentially different purposes than those for which they are now being used. The result has been a set of transportation and air quality models that are not effectively interrelated in terms of important underlying relationships. However, new modeling tools can be used to obtain improved linkages among transportation, emissions and air quality analyses. This paper demonstrates and tests activity-based travel demand models and household sample enumeration forecasting techniques to evaluate the transportation and air quality impacts of travel demand management strategies. Data from the Portland, Oregon metropolitan area is used to evaluate three transportation policies: transit improvements, pricing and telecommunications. The policies are evaluated both individually and in combination. The activity-based models used in this testing represent a significant improvement over the current four-step sequential model systems by providing a deeper insight into the individual decision making process in response to transportation policies. A wider range of impacts is predicted, and indirect effects as well as synergistic effects of such polices are taken into consideration. Testing using hypothetical policies shows that, by improving the prediction of variables that are important in estimating impacts of transportation actions, these models are capable of providing the information needed to improve the linkage of transportation models with emissions and air quality analytic practices.
