Intelligent transportation could be seen as a high-tech search for the road less traveled. It strives for improved traffic flow to ensure safer, quicker, less expensive, and more-energy-efficient travel.
Many intelligent transportation systems (ITS) are being designed to better manage traffic on well-traveled roads to reduce congestion and achieve these goals. Inside cars, navigational systems with display panels are intended to guide drivers around heavy traffic and help them avoid accidents. Traffic management technologies are designed to communicate with drivers on busy interstate highways through navigational systems and variable message signs.
