Operational Testing of Two Interim Products from the Travel Model Improvement Program (1.35MB)

This document provides a high-level overview of the features of the TRANSIMS software package that were used in the Portland Case Study. As TRANSIMS-DOT was not completed during the period covered by this project, the project team had to perform the case study in collaboration with Los Alamos National Laboratory and Portland Metro using the Portland area databases.

TRANSIMS is not a model. It is a modeling system that permits the modeler to keep track of and modify the behavior of each individual in a synthetic population. The TRANSIMS technology consists of software modules and file protocols that make this modeling possible. The purpose of the Portland Study is not to develop a complete calibrated model of 1996 Portland. Rather, it allowed the developers of the system to understand transportation planning methods and the models and data that support these methods.
