advanced communications, navigation, information-gathering, and operations-monitoring technologies used to enhance transportation mobility, efficiency, and safety
ITS encompasses a broad range of modern computer and communications technologies. When integrated into the transportation system infrastructure or in vehicles, these technologies help monitor and manage traffic flow, reduce congestion, provide improved mobility, safety, air quality, and productivity. TRIMARC is an example of ITS. Subsets of Intelligent transportations systems include ATIS, ATMS, and Incident Management or Response Systems.
