Intelligent Transportation Systems
Intelligent Transportation Systems, known as ITS, are electronics, communications, or information processing used to improve the efficiency or safety of the transportation system. As documented in the Transportation Systems Management and Operations program plan, the Iowa DOT manages more than 1,000 intelligent transportation system devices and approximately 750 miles of Iowa DOT owned and shared fiber-optic cable across the state. ITS devices currently managed by the DOT include everything from closed-circuit television cameras and dynamic message signs to over-height detection systems and road weather information systems.
Intelligent Work Zones
Since 2014, Iowa has taken a comprehensive, statewide approach to deploying ITS on work zones. Temporary, portable cameras, sensors and dynamic message signs are deployed on multiple construction projects every year through a statewide contract, which also ensures all devices and systems are integrated and coordinated into the statewide Traffic Management Center. Additional work zone information is available on the Work Zone Reference Library.
