Abstract
An arrangement for requesting preemption from a vehicle is used in a traffic control system. The arrangement for requesting preemption includes a protocol circuit, a signal control generation circuit, and an optical source. The protocol circuit is adapted to provide a plurality of communication protocols, wherein a plurality of the communication protocols communicate encoded data. The signal control generation circuit is adapted to generate an output signal in accordance with at least one of the plurality of communication protocols. The optical source is adapted to transmit light pulses from the vehicle, wherein the light pulses are generated from the output signal and include the encoded data for said at least one of the plurality of communication protocols.
