Signature Project 1B – Integrated Land-Use, Transportation and Environmental Modeling

Land use and transportation are inextricably linked. Models that capture the dynamics and interactions of both systems are indispensable for evaluating alternative courses of action in policy and investment. The Integrated Modeling Project seeks to implement several versions of an integrated land-use / transportation model for Chittenden County, Vermont. Based on those results, the authors hope to evaluate the benefits of increased complexity and disaggregation in modeling of land-use, travel demand, and travel supply (route choice and traffic assignment) relative to the costs. Working collaboratively with local and regional planners, the project also seeks to develop alternative policy scenarios that can be evaluated using these different model configurations. By evaluating the sensitivities of baseline and alternative policy scenarios to different configurations and complexity levels for the integrated model, the authors hope to gain insight about how the appropriateness of model disaggregation and complexity may also vary with policy application. Towards this end the project compares an integration of the dynamic UrbanSim land use model with a static traffic assignment (TransCAD) to a more complex integration of UrbanSim with a traffic simulation (TRANSIMS) and trip generation from TransCAD. Finally, the Environmental Metrics Project seeks to develop tools for generating environmental indicators from the outputs of the integrated models, which will allow for evaluation of scenarios on the basis of environmental metrics.
