A guidance control system is disclosed for a traction vehicle arranged to be displaced along a guide path which consists of a plurality of closed loop vertical antennae embedded beneath the surface along the path of travel. The vehicle is in two way radio communication with wayside stations equipment. Destination information in binary coded form is encoded on the vehicle and sent to the proximate loop antenna; the fact that this coded information is received at a particular segmented antenna at once identifies the location of the vehicle as well as conveys the destination intelligence. A central processor, receiving the location and destination information, of this and all other vehicles, serves as a master control to discipline each vehicle from one segmented loop to the next. From the central processor the wayside station sends traction signals to each segmented antenna loop respectively. Additionally, the fact that traction signals are sent to the vehicle over a single segmented loop at a time, establishes a magnetic field over a narrow region, and a dual antennae arrangement on the vehicle senses the magnetic field to produce error signals to steer the vehicle with precision back to the guide path.
