A pivotal reorganization

As the leader of the Connected Corridors program, Caltrans has demonstrated its commitment to ICM by adopting a reorganization plan to better support corridor management in the state. The plan establishes Corridor Managers to serve as experts for individual corridors, responsible for overseeing corridor operations, coordinating with partner agencies, and improving collaborative, multi-agency planning. This corridor-focused reorganization effort by a state Department of Transportation—the first of its kind in the nation—recognizes both the importance of a systems approach to transportation management and the foundational need for inter-agency collaboration to successfully carry out ICM initiatives like Connected Corridors.

TSM&O

Caltrans' reorganization takes place within the larger framework of Transportation Systems Management and Operations (TSM&O), on which ICM is based. As defined in the Moving Ahead for Progress in the 21st Century Act (MAP-21), TSM&O means “integrated strategies to optimize the performance of existing infrastructure through the implementation of multimodal and intermodal, cross-jurisdictional systems, services, and projects designed to preserve capacity and improve security, safety, and reliability of the transportation system.” Caltrans Director Malcolm Dougherty describes the agency's TSM&O vision in Moving Toward TSM&O, and additional guidance on TSM&O can be found on the AASHTO website at http://www.aashtotsmoguidance.org.

CMM

One of the tools supporting Caltrans' TSM&O philosophy is the Capability Maturity Model (CMM). Adapted for the transportation community by the Strategic Highway Research Program (SHRP 2), CMM identifies the key process and institutional capabilities required from a transportation agency (or group of agencies) to achieve effective TSM&O. It describes an arc of improvement that moves from separate, ad hoc processes toward mature, cross-functional, integrated operations.
 
The application of CMM to Integrated Corridor Management is described in Advances in Strategies for Implementing Integrated Corridor Management (ICM), a Scan Team Report supported by the National Cooperative Highway Research Program (NCHRP). The following table from the report lays out the improvement path in five levels and captures the essence of the Capability Maturity Model as applied to ICM:
