ABSTRACT:
An external indicator for use in proximity to an on-board unit or transponder for an electronic toll collection (ETC) system. The external indicator senses RF transmissions from the on-board unit and/or roadside readers of the ETC system and produces sensory outputs when transmissions are detected. The external indicator receives RF signals, demodulates them, and analyses the demodulated RF signals to determine if it has received a roadside reader trigger signal and/or a transponder response signal. A sensory indicator, such as a visual, auditory, or kinetic device, alerts an occupant of a vehicle to the detected RF transmissions and, accordingly, to the likely occurrence of an ETC transaction.
