The invention provides a traffic-aware routing method applied to Internet of Vehicles. A data packet is transmitted from a starting point to a destination point through forwarding between nodes, wherein the forwarding of the data packet comprises data packet forwarding at an intersection and data packet forwarding in a straight road section, and an intersection road section needs to be selected according to road condition information of each road section which is broadcast by a data collection package at the intersection when the forwarding is carried out at the intersection. According to themethod, the problems of unstable link and large transmission delay are avoided, and the local optimum problem in the geographic routing is solved.
