Intelligent Transportation Systems

The Center for Transportation Analysis does specialty research and development in intelligent transportation systems.

Intelligent Transportation Systems (ITS) are part of the national strategy for improving the operational safety, efficiency, and security of our nation's highways. Since the early 1990s, ITS has been the umbrella under which significant efforts have been conducted in research, development, testing, deployment and integration of advanced technologies to improve the measures of effectiveness of our national highway network. These measures include level of congestion, the number of accidents and fatalities, delay, throughput, access to transportation, and fuel efficiency. A transportation future that includes ITS will involve a significant improvement in these measures while remaining environmentally friendly, and assuring the safety and security of the traveling public. The CTA conducts ITS research to support such a future. During the ITS/Intelligent Vehicle Highway System (IVHS) era, the CTA has conducted more than 50 major ITS projects.
