ABSTRACT:
Methods and apparatus for the automatic and management of traffic, utilizing a microprocessor-based, read-write vehicle borne transponder device. The system includes plurality of transceivers spaced along and positioned adjacent to a roadway, a plurality of vehicle borne transponders, and an independent network management computer. As vehicles traverse the roadway the transponders communicate with the transceivers and one or both of those units collect information such as, vehicle entrance point, vehicle exit point, vehicle speed, number of passengers in each vehicle, and vehicle class. Some of the collected information is processed by the transceivers and transponders, while other information is transmitted to the network management computer for processing.
