Abstract:The U.S. Department of Transportation Integrated Corridor Management (ICM) Initiative aims to advance the state of the practice in transportation corridor operations to manage congestion. Through the deployment of ICM at the two selected Demonstration Sites (Dallas, Texas and San Diego, California), this initiative thoroughly investigated and documented the impacts of the ICM deployments, especially in regards to improved agency coordination. Analysis, Modeling, and Simulation (AMS) efforts assisted corridor partners to optimize their ICM deployment, and supported the broader evaluation effort for the entire ICM Initiative. Using AMS enabled corridor partners to identify the strategies to include in their ICM System that would be most effective against their specific corridor congestion issues, by providing measureable results for multiple alternatives. The focus of this ICM Post-Deployment assessment is to investigate the impacts of the ICM system in its “as deployed” state on U.S.-75 in Dallas, using AMS tools and techniques developed and refined under both the current and previous phases of the program. The localized ICM strategies deployed include improved multimodal traveler information, parking management system at park-and-ride facilities, interdependent incident response plans, route/mode shift/diversion, and increased transit capacity. A framework of the key activities required for post-deployment AMS, namely model enhancements, model calibration and validation, cluster analysis and incident matching, and alternatives analysis results, is presented in this report. Mobility performance results for the site indicate an expected annual savings of 22,004 person hours in peak directions of travel, while expected cumulative annual variability improvements for the northbound afternoon peak direction amounted to 20,145 hours.
