The system comprises a plurality of elongated, electrically connected inductor modules arranged in an aligned end to end spaced apart order to form a continuous vehicle path. Each module has a magnetic core and power windings which generate a magnetic field extending above the road surface. Controllable relays are connected between modules for allowing operating electric current to either activate or bypass selected modules. Sensing windings in modules are activated by the presence of a vehicle on one module to provide control signals to relays for other modules. | |
