OPERATIONAL TESTING OF TWO INTERIM PRODUCTS FROM THE TRAVEL MODEL IMPROVEMENT PROGRAM

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. Additionally, there are three demonstration purposes of this study: (1) To show that the software runs for a regional problem on available computers in a reasonable amount of time; (2) To show that TRANSIMS can be made responsive to the variables and conditions that planning organizations deem to be important, and that models produced by TRANSIMS may be calibrated for use in a forecast setting; and (3) To show that it is possible to develop TRANSIMS meta-methods and methods that would allow matches to Portland traffic and transit counts for a base year. The Los Alamos National Laboratory TRANSIMS development team is working closely with the Portland Metro modeling staff to perform comparisons with existing Portland data and conduct a review of the case study. The project team will continue to work with these entities in the future to examine the potential of applying TRANSIMS technologies in Florida.
