AASHTO Committee on Transportation System Operations (CTSO)


CSTO focuses on transportation system operations and associated intelligent transportation systems (ITS) and emerging technologies with a goal of improving safety, system reliability, and highway system performance.  This committee strives to transform the national transportation community to a transportation systems management and operations (TSMO) culture and guides the National Operations Center of Excellence (NOCoE) and the AASHTO Operations Technical Service Program, in collaboration with the Institute of Transportation Engineers (ITE) and the Intelligent Transportation Society of America (ITS America).  The CTSO provides leadership for AASHTO with regard to highway transport and commercial vehicle safety, size and weight issues, and coordinates with the commercial vehicle industry and its representative associations regarding vehicle design, standards, and practices associated with commercial motor vehicle operations.  The committee serves as a depository of technical information, solutions, and advice on transportation-related communication systems and equipment, including Cooperative Automated Transportation (CAT) integration, operations-related cyber security, protecting sufficient communication spectrum to meet the needs of the member departments, and representing the interests of AASHTO and its member departments in proceedings before Federal agencies on telecommunications matters.

The Subcommittee on Operations is composed of membership from the Working Groups on Operations Strategies, Operations Implementation, and Freight Operations. The Subcommittee on Technology is composed of membership from the Working Group on Communications Technology, Cooperative Automated Transportation (CAT), and Intelligent Transportation Systems (ITS). Additionally, CTSO also promotes the implementation of Road Weather Management (RWM) solutions and strategies through the Community of Practice on Road Weather Management.. The recently formed Joint Subcommittee on System Mobility and Emerging Technologies (formerly “System Performance Subcommittee” under CPBM – “Performance Measurement and Data Subcommittee” under CTSO), serve as the central forum to share information on how state DOTs are managing system operation and system mobility and how performance is impacted due to current and emerging transportation technologies, programs, operational strategies and connected environments.
