Integrated Corridor Management: Analysis, Modeling and Simulation (AMS) Results for the Test Corridor

This article describes the U.S. Department of Transportation’s Integrated Corridor Management (ICM) initiative, aimed at demonstrating how Intelligent Transportation Systems (ITS) technologies could reduce congestion, and the analysis, modeling and simulation (AMS) methodology to help transportation planners determine the best ICM strategies under different conditions. In fall 2008, USDOT will begin applying the AMS methodology to analyze potential benefits of proposed ICM strategies at three test sites: Dallas, Texas; Minneapolis, Minnesota., and San Diego, California. The article describes the ICM AIMS approach, the test corridor chosen to serve as the testbed, operational conditions of the test corridor, performance measures used, estimated costs, and ICM benefits. The analysis team chose the San Francisco Bay Area’s I-880 corridor as the testbed for the AMS methodology. The article’s authors conclude that the test corridor modeling validated the ICM concept; it is able to analyze individual and combination effects of ICM strategies under different operational conditions.
