Intelligent Transportation Systems (ITS)

Intelligent Transportation Systems (ITS) represent the application of advanced sensing, information processing, control, and communications technologies to transportation infrastructure and vehicles to improve safety, mobility, and efficiency. By creating an integrated network where vehicles, roadways, and traffic management centers can share real-time data, ITS enables dynamic solutions such as adaptive traffic signal control that responds to actual traffic flow, real-time traveler information systems that warn of congestion or hazards, electronic toll collection, and connected vehicle technologies that help prevent collisions. The ultimate goal of ITS is to manage the complex interactions within the transportation system to reduce travel times, minimize accidents, and lessen the environmental impact of travel for a smarter and more coordinated network.
