50717, has been approved in late 2022. Following standards, encompassing "full interoperability" and a "unified and interoperable solution" for ground-level power supply, are scheduled to be published by the end 2024, detailing complete "specifications for communication and power supply through conductive rails embedded in the road". The first permanent electric road in Sweden is planned to be completed by 2026 on a section of the E20 route between Hallsberg and Örebro, followed by an expansion of further 3000 kilometers of electric roads by 2045. Inductive The Online Electric Vehicle developed by KAIST, the Korea Advanced Institute of Science and Technology, uses inductive vehicle charging. Its system has inductive coils built into the road that delivers power to receivers mounted on the underside of electric vehicles. Commercialization of the technology has not been successful, leading to a controversy over the continued public funding of the technology in 2019. The German company IAV developed similar technology in 2009. As of 2021, companies such as Magment, Electreon, and IPT are currently developing dynamic inductive coil charging technologies. Additionally, IPT is developing a system that uses inductive rails instead of coils, as the current standards which use coils that were deemed "extremely expensive" for dynamic charging, according to its CEO. Usage for road markings The Smart Highway concept developed by Studio Roosegaarde and the infrastructure management group Heijmans in the Netherlands incorporated photo-luminescent paint for road markings, which absorb light during the day then glow for a period up to 10 hours. In its first design, the Glowing Lines charges during the daytime and glows for several hours at night to create a positive highway experience and increase safety. In April 2014, a pilot stretch of highway in Brabant, Netherlands was officially opened, demonstrating the technology. After two weeks, the paint had stopped glowing due to issues with moisture. Frost protection and melting snow, ice Snowmelt systems using electricity or hot water to heat roads and pavements have been installed in various locations. Solar Roadways has proposed including a snowmelt system with their photovoltaic road panels, since the panels already have electrical power connections for harvesting photovoltaic power. Critics point to the very large energy requirements of such a system (much greater than the energy collected by the roadway in ideal conditions). ICAX Limited of London's "Interseasonal Heat Capture" technology captures solar energy in thermal banks and releases it back under a roadway, heating
