description The invention discloses a fog computing based road information service system and method during city traffic congestion. The system comprises a vehicle-mounted intelligent terminal, a fog server, a roadside unit and a roadside cloud server module. The method comprises the following steps: 1, constructing a local area network; 2, positioning a vehicle; 3, sending a service request; 4, receiving the service request; 5, planning a driving route; and 6, feeding back an optimal path. According to the invention, the local area network is constructed by use of the fog server, real-time road condition information under jurisdiction is collected and is transmitted to the roadside unit governing the fog server, the roadside unit plans the driving route according to destination address information of the vehicle and the real-time road condition information, and the system and method are enabled to have the advantages of low delay, position perception, wider geographical distribution, suitability to more nodes and less d
