An Improved Roadway Guidance System provides guidance elements in a roadway as means to guide a vehicle along the roadway, as well as supply important information to the vehicle to enhance the autonomous operation of the vehicle in a safe and efficient manner. The system comprises at least three parts: (1) the use of overlaid roadway “emitter strips” that provide an extended excitation/emission field simultaneous with direct guidance instructions to passing vehicles; (2) the use of a linearly-arranged antenna array system provided on the vehicle and adapted for interaction with the emitter strips for positionally locating the vehicle within a travel lane and providing additional informative data for operation of the vehicle; and (3) the use of a multi-port Receiver Unit that works with the antenna array and the host vehicle's guidance system to optimize autonomous operation of the vehicle.
