Claim 35:
36. A method of using a roadway guidance system comprising the steps of:
transmitting energy pulses from a vehicle to an emitter strip located on a roadway, the emitter strip including an emitter and a plurality of strip antennas, the emitter being in communication with each strip antenna of the plurality of strip antennas through a common feed line;
receiving, by each of the plurality of strip antennas, the energy pulses;
generating, by each of the plurality of strip antennas, excitation energy from energy of the energy pulses;
transmitting, by each of the plurality of strip antennas, the excitation energy to the emitter;
detecting, after the transmitting said energy pulses, whether return signals are received by a receiver apparatus associated with the vehicle;
comparing, by the receiver apparatus, the received return signals in order to determine relative signal strengths of the received return signals;
determining an estimated position on the roadway based on the determined relative signal strengths;
comparing the estimated position on the roadway with a predefined position on the roadway; and
sending at least one of steering correction and breaking braking correction to a vehicle computer to adjust the position of the vehicle.
