Technology for automatically and uniquely identifying vehicles in motion has been under development and testing since the early 1960s and is receiving increasing attention. Systems using this technology make possible nonstop collection of tolls and other road user charges. Other potential applications include traffic control, law enforcement, and fleet management. This report summarizes recent developments of the technology. A coding format has been developed that is suitable for standard use. An intermediate generation of radio frequency equipment did not perform as expected, but a new generation is about to be tested. A system using microwaves is being developed and tested. An optical system is delivering good performance and reduced-rate cash toll collection. Studies of cost elements in a nonstop toll collection system, such as account maintenance, are being conducted. Market research is under way. /Author/
