GLPS
Ground-level power supply, also known as surface current collection or, in French, ''alimentation par le sol'' ("feeding via the ground"), is a concept and group of technologies that enable electric vehicles to collect electric power at ground level instead of the more common overhead lines. Ground-level power supply systems date to the beginning of electric tramways. Often they were implemented where the public expressed an aesthetic desire to avoid overhead lines. Some of the earliest systems used conduit current collection. Systems in the 21st century, such as Alstom APS, Ansaldo Tramwave, CAF ACR, and Elways, were developed to modern standards of safety and reliability, and added the ability to supply power to electric buses, trucks, and cars. Some ground-level power supply systems use efficient, energy-dense capacitors and batteries to power portions of an electric transit system—for example, enabling buses and trains to charge their batteries during station stops. ...

Electric Road
An electric road, eroad, e-roadway, or electric road system (ERS) is a road which supplies electric power to vehicles travelling on it. Common implementations are Overhead line, overhead power lines above the road, ground-level power supply through conductive rails, and dynamic wireless power transfer (DWPT) through Inductive charging#Transportation, resonant inductive coils or inductive cables embedded in the road. Overhead power lines are limited to commercial vehicles while ground-level rails and inductive power transfer can be used by any vehicle, which allows for public charging through a system for power metering and billing. Of the three methods, ground-level conductive rails are estimated to be the most cost-effective. Government studies and trials have been conducted in several countries seeking a national electric road network. South Korea, Korea was the first to implement an induction-based public electric road with a commercial bus line in 2013 after testing an experime ...
