Integrated Corridor Management (ICM) is an operational concept that seeks to reduce congestion and improve performance by maximizing the use of available multimodal capacity across a corridor, including highways, arterial roads and transit systems.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 287: Planning and Implementing Multimodal, Integrated Corridor Management: Guidebook, developed by Cambridge Systematics’ Alice Marecek, provides an overview of current recommended practices and outlines critical components for the planning, design and development, and operations and maintenance of an ICM system.
