The invention relates to a multi-layer three-dimensional traffic electrification scheme formed by roads (including overhead roads, bridges, tunnels and the like) for the running of motor vehicles. With the multi-layer three-dimensional traffic electrification scheme of the present invention, the congestion problem caused by insufficient road traffic resources can be improved, and particularly electric vehicles can be continuously supplied with driving electric power and special lanes so as to significantly improve the continuous endurance of the electric vehicles and achieve the unmanned driving; and the multi-layer three-dimensional traffic electrification scheme is completed by the multi-layer three-dimensional overhead road and the power transmission system configured on the special lane so as to form the multifunctional road system with advantages of high traffic capacity, unlimited endurance and unmanned driving.
