Abstract

An apparatus, method, and system for detecting and counting vehicles on a roadway are presented. The roadway need not be partitioned into directional lanes. The matrix may have a plurality of matrix elements in communication with a master matrix element. Each matrix element contains two sensors, a processor and a transceiver. Matrix elements transmit sensor data to the master matrix element, which uses the sensor data to calculate the number of vehicles traveling through the detection area of the sensor matrix, and the point of entry and the point of exit of each such vehicle.
