What we do

As part of the Transportation Operations Group at TTI, the System Reliability Division conducts a wide variety of research, implementation, and technology transfer activities in the advanced areas of traffic operations and connected transportation. Total division funding is more than $20 million from a variety of Federal, State, Local, and Private-Sector sponsors. The division is comprised of two programs: Advanced Transportation Operations and Connected Infrastructure.

Advanced Transportation Operations Program

The Advanced Transportation Operations program improves operations through the application of expertise, innovative technologies, and superior performance.  Research is conducted across the operations arena using innovative technology deployments and the collection, analysis and presentation of data to both operators and users of the system.  Intelligent Transportation Systems (ITS), Traveler Information, Incident Management, Performance Metrics, and Transportation System Management and Operations (TSMO) are some of the many research areas.

Connected Infrastructure Program

The Connected Infrastructure program integrates infrastructure into the cooperative and connected environment to create systems that are self-aware, reactive to prevailing conditions, and support and enhance information exchange between roadside, devices, and vehicles.  Research is conducted across a broad range of infrastructure including roadside devices, traffic signals, signage, work zone environments, and more.  Through this broadly connected paradigm, the program seeks to improve safety and mobility as well as address environmental, economic and efficiency concerns.


The Division conducts research in the following traditional and strategic topics, all of which support the vision and mission of the Division: To transform transportation operations, reliability, mobility, and safety through the application of innovative concepts, tools, and technologies.
