The TRANSIMS model represents a new generation of transportation planning models. An activity-based model is used to represent transportation demand where the travel patterns of individuals from a synthetic population are modeled explicitly. A digital network and a microscopic based model represent transportation supply. The interaction between demand and supply, at both a temporal and spatial level is modeled using an interactive approach. The fact that TRANSIMS simulates on the level of the individual traveler makes it possible to quantify a wide range of performance measures at a highly disaggregate level. The quantified performance measures can then be used in various applications related to transportation decision-making. The focus of this paper is to show how the disaggregate output from TRANSIMS can be used to quantify a wide range of sustainable transportation performance measures and how the quantified performance measures can be used to make a decision regarding a possible capital improvement project. The test bed for this research is comprised of a 22 km section of the Interstate 10 corridor in Houston, Texas. The capital improvement project analyzed involves the determination of an appropriate section of the freeway that should be widened to be continuously four lanes. The paper is broken down into three sections. The first section provides an overview of the TRANSIMS model. The second section provides a description of the test bed. The third section describes how the fairly coarse individual speed profiles produced by TRANSIMS can be smoothed. The final section illustrates how a multi-criteria decision making technique can be used to make decisions using the quantified performance measures.

The CD-ROM contains the proceedings of the sixth, seventh and eighth conferences. The eighth conference proceedings were published in October 2001.
