A vehicle guidance system consists of an environmental state monitoring device, a plurality of vehicle position detection devices and a vehicle-mounted device; the plurality of vehicle position detection devices are arranged along an extending direction of a guidance road segment, and the vehicle-mounted device is arranged on a vehicle; the environmental state monitoring device is electrically connected with a triggering device, and a termination device and a follow-up device are electrically connected with the triggering device; each vehicle position detection device can communicate with the vehicle-mounted device in a radio frequency communication mode; the environmental state monitoring device can monitor the environmental state of a region where the guidance road segment is; the vehicle position detection devices can detect whether a vehicle passes on the corresponding road segment; and the vehicle-mounted device can analyze radio frequency signals sent by the vehicle position detection devices and shows analyzed information to a driver and a passenger. The vehicle guidance system provided by the invention has the beneficial technical effects of being capable of guiding the vehicle to safely pass the road segment in a fogging period, enabling an expressway to bear certain traffic flow in the fogging period, and improving the traffic condition in the fogging period.
