The U.S. Department of Transportation (USDOT) is working to advance the state of the practice in integrated corridor management (ICM). This article describes the USDOT's ICM Initiative, which focuses on providing real-time traveler information and multimodal operations and using technology to reduce congestion. The ICM Initiative has three objectives: (1) demonstrate how operations strategies and intelligent transportation system (ITS) technologies can speed the movement of people and goods in major transportation corridors through integrated management of all networks in a corridor; (2) develop a toolbox of operational policies, cross-network operational strategies, integration requirements and methods, and analysis methodologies needed to implement effective ICM systems; and (3) demonstrate how proven and emerging ITS technologies can coordinate operations between separate corridor networks to increase effective use of the corridor's total transportation capacity. The USDOT has selected eight sites that are recognized leaders in congestion management to act as partners in the development, deployment, and evaluation of ICM strategies. Their efforts under the ICM Initiative are expected to contribute directly to more efficient, faster moving, and safer corridors for the future. The ICM Initiative will be implemented in four phases designed to promote innovation in the development of new approaches for managing existing assets efficiently within a corridor. Ultimately the phases will help USDOT and the pioneer sites identify and advance promising ICM approaches that can serve as critical next steps in the Nation's efforts to reduce traffic congestion. USDOT expects to make available the pioneer sites' concepts of operations and requirements documents, as well as lessons learned from these activities, by Summer 2008. Early results from the analysis and modeling efforts using the test corridor also should be available by Summer 2008. To share knowledge with interested transportation practitioners, USDOT also plans to host panel discussions, workshops, and webinars over the next year.
