Issues and concepts related to microwave and millimeter wave product applications for Intelligent Transportation Systems are surveyed. There is very significant worldwide opportunity and activity in improving transportation infrastructure by using capacity and safety enhancing products. Product opportunities for microwave and millimeter wave products can be grouped into a few major categories. Those which provide driver navigation and congestion information, those which aid in driver safety and occupant comfort, those which aid in vehicle location and security, and those which improve traffic capacity and flow. Typically these are microwave and radiowave roadside beacons for monitoring pollution, congestion, traffic flow, cross-section management, traffic density, and road hazard. Also for communication, these include cellular and pager systems, DSRC (Direct Short Range Communications) transponders for automatic toll collection and MayDaytype emergency dispatch transponders. Additionally, using GPS (Global Positioning Satellite) signals and detailed cartological information, communication interfaces are needed for navigation support. Finally, millimeter wave radar systems for lCC (Intelligent Cruise Control), lane change aid and back-up warning products for HOV (High Occupancy Vehicle) platooning are used.
