An information transmission frequency optimization method based on a vehicle traveling state field model in Internet of Vehicles, relating to the technical field of network communications. In the method, a traveling state field model is created on the basis of the real-time operation state of an on-road vehicle to describe the risk level of the vehicle; the risk level can be used for dynamically adjusting the transmission frequency of safety information; the transmission frequency of non-safety information is adjusted according to the real-time transmission frequency of safety information so as to achieve the purpose of improving link utilization rate. According to the present method, a traveling state field model of a moving vehicle is created, the risk level of the vehicle in the traveling state field is used for describing the current traveling risk of the vehicle, and in addition, because different application scenarios are considered, the method is widely applicable. Moreover, the improved network resource optimization method can effectively improve the communication efficiency of heterogeneous networks, and dynamically adjust the safety information transmission frequency according to the risk level, so that the link utilization rate is improved.
