Abstract
A traffic monitoring, driver assistance, and communications system includes lane terminals arranged along a direction of travel of a highway, each lane terminal including a sensor for detecting passage of a vehicle, a communication antenna, a terminal transceiver for communicating with a passing vehicle through the communication antenna, and a network backbone linking the lane terminals to a data processor for compiling information on passing vehicles sensed. The system permits complex toll assessment on toll roads. By using a larger number of short range antennas, cellular communication is possible with a very large number of moving vehicles without increasing bandwidth because the cells are relatively small.
