The invention relates to a crossroad and a going-through method of an intelligent magnetic-navigation vehicle. The crossroad is built at the intersection position of multiple cross ways and comprises an annular track, a communication base station and a magnetic track spike, wherein the annular track adopts double lanes and comprises an outer annular road and an inner annular road, the communication base station is arranged at the central part of the inner annular road and is connected with a remote monitoring server, and the magnetic track spike is paved on the surface of the cross way and the annular track; the going-through method comprises the following steps: the magnetic track spike is adopted for encoding to achieve accurate location of the vehicle at the crossroad, and the communication base station is adopted to perform vehicle scheduling and handle emergency stop, so that the intelligent magnetic-navigation vehicle can be smoothly driven in the whole journey. Compared with the prior art, the crossroad and the going-through method of the intelligent magnetic-navigation vehicle have good universality and expansibility and can effectively solve the problems of the start and stop actions of the vehicles and the complex scheduling of the remote monitoring center, and the running efficiency of the intelligent transportation system is greatly improved while the energy is saved.
