Integrated Corridor Management – Tools, Strategies and Deployment Support

U.S. Department of Transportation

Objective

The objective of the Integrated Corridor Management (ICM) initiative is to demonstrate how intelligent transportation systems (ITS) technologies can efficiently and proactively manage the movement of people and goods in major transportation corridors. For the U.S. Department of Transportation (U.S. DOT), Cambridge Systematics is leading the analysis, modeling, and simulation (AMS) activities of the ICM initiative. The objectives of the AMS effort are to refine analysis tools and strategies, assess data capabilities at eight Pioneer Sites, conduct AMS for three Stage 2 ICM Pioneer Sites, and conduct AMS tools post-demonstration evaluations.

Our Approach

The overall AMS effort includes the following tasks:

  1. Identify AMS data needs and assess Pioneer Site capabilities.
  2. Develop methodologies to model ICM strategies – including macroscopic travel demand models, and mesoscopic/microscopic traffic simulation models.
  3. Test and validate these methodologies in a test corridor.
  4. Use AMS methodologies and existing tools to model three Pioneer Site corridors, including I-15 in San Diego, I-394 in Minneapolis, and U.S. 75 in Dallas. This will help identify cost-effective ICM strategies, and help prioritize ICM investments based on expected performance.
  5. Validate methodologies and tools based on Pioneer Site demonstrations. The overall effort will result in validated and tested methodologies to support ICM analysis.

Project Results

Efforts under this project focus on analyzing the ICM systems proposed by the Stage 2 Pioneer AMS Sites and evaluating the expected benefits to be derived from implementing those ICM systems. The overall benefits of this effort include:

  1. Helping decision-makers identify gaps, evaluate ICM strategies and invest in the best combination of strategies that would minimize congestion and improve safety;
  2. Helping estimate the benefit resulting from ICM across different transportation modes and traffic control systems; and
  3. Transferring knowledge about analysis methodologies, tools, and possible benefits of ICM strategies to the Pioneer Sites and to the entire transportation community.
