Abstract

The electric highway includes at least one electrified lane that may be separated from other non-electrified lanes by a non-elevated strip of dividers, a roadside subsystem that includes a system operation monitoring center that monitors system operation; a plurality of roadside conductor assemblies, each of which includes at least one roadside conductor laid within a coaxial pipe made of a non-magnet field shielding material, and its/their housing in the traffic lane; a roadside part of an on-board part of a lateral location sensor; a plurality of roadside controller each of which includes a power supply assembly, at least one communication device housed in a roadside box, and a plurality of roadside posts with a camera affixed to it. The electric highway system is monitored continuously at the system operation monitoring center.

Claims
