Overview
The efforts to date to reduce surface transportation congestion have focused on optimization of individual networks. Corridors offer an opportunity to operate and optimize the entire system as opposed to the individual networks. Through the Integrated Corridor Management Systems initiative, the U.S. DOT will provide guidance to assist agencies in implementing Integrated Corridor Management, create supporting analysis tools, approaches, and technical standards, and demonstrate the value of ICM.
Corridor Networks Today
Transportation corridors often contain unused capacity in the form of parallel routes, the non-peak direction on freeways and arterials, single-occupant vehicles and transit services that could be leveraged to help reduce congestion. Traffic information today is often fragmented, outdated or not completely useful. Networks are often independently operated and efforts to date to "reduce congestion" have focused on optimization of individual networks.
The ITS Opportunity
The combined application of technologies and a commitment of network partners to work together have the potential to transform the way corridors are operated and managed. Thanks to recent advancements in intelligent transportation systems technologies, there is a tremendous opportunity today to integrate operations to manage total corridor capacity.
With ICM, the various institutional partner agencies manage the transportation corridor as a system-rather than the more traditional approach of managing individual assets. They manage the corridor as an integrated asset in order to improve travel time reliability and predictability, help manage congestion and empower travelers through better information and more choices.
In an ICM corridor, because of proactive multimodal management of infrastructure assets by institutional partners, travelers could receive information that encompasses the entire transportation network. They could dynamically shift to alternative transportation options-even during a trip-in response to changing traffic conditions. For example, while driving in a future ICM corridor, a traveler could be informed in advance of congestion ahead on that route and be informed of alternative transportation options such as a nearby transit facility's location, timing and parking availability.

Spotlight on the Four Phases of the U.S. DOT's ICM Initiative
The U.S. DOT's seven year ICM Initiative will occur in four phases. These phases are designed to promote innovation in the development of new approaches for efficiently managing existing assets within a corridor. Ultimately, these four phases will help the U.S. DOT and the Pioneer Sites to identify and advance promising ICM approaches that can serve as critical next steps in the nation's efforts to reduce traffic congestion. Note that Phases 2-4 occur concurrently to some extent.
Phase 1: Foundational Research
Phase 2: Corridor Tools, Strategies and Integration
Phase 3: Corridor Site Development, Analysis and Demonstration
Phase 4: ICM Outreach and Knowledge and Technology Transfer
Research Findings and Test Results
Research findings and test results from the ICM Initiative are summarized here and also stored in the ICM Knowledgebase, the searchable, browseable online repository of research reports, documents and other knowledge transfer resources from the ICM Initiative.

ICM CONOPS and System Requirements
The development of an ICM Concept of Operations, or "CONOPS," is the first step toward the implementation of ICM in a corridor. In this foundational step, partner agencies along a transportation corridor work together to develop a detailed concept for operating and managing the corridor as a system of systems. The ICM CONOPS document describes this concept-and includes detailed institutional, operational, and technical implications-to support a shared vision for ICM corridor operations, and development of requirements. In addition, the CONOPS needs to clearly describe why the proposed system is needed and what the needs are for the system. With a complete CONOPS, partner agencies then develop and document Systems Requirements Specifications for their ICM system (ICMS) mapping back to their needs identified in their CONOPS. These two documents guide ICMS design.

The ICM Initiative is truly an integrated initiative. This philosophy is reflected in the joint management of the initiative shared by senior representatives from the Research and Innovative Technology Administration's (RITA) Intelligent Transportation Systems (ITS) Joint Program Office (JPO), Federal Highway Administration (FHWA) and Federal Transit Administration (FTA). In addition to proactively involving stakeholders in the development of everything from the initial concept of the initiative to the strategic plan for ICM outreach and knowledge and technology transfer, the ICM Initiative is jointly directed by a "Core Team" of U.S. DOT leaders:
