Research on a Spatio-Temporal Calibration Method for Transport Monitoring Data Based on V2I Communication System

As more mobile monitoring devices are used in highway transportation monitoring, more data need to be transmitted. Many of them not only contain index data, but also contain time data and location information. These monitoring data often have a high update frequency and need to be transmitted quickly to data users. V2I communication systems are an important part of the intelligent transportation system. This paper proposes a regional spatio-temporal calibration method based on data sharing. The method can be used to realize the high-frequency transmission of monitoring data through the V2I communication system with limited transmission capacity. This paper first analyzes the influence of vehicle communication network topology on spatio-temporal calibration mechanism. Second, the working principle and implementation process of the regional spatio-temporal calibration method are proposed. Finally, the application effect of the method is analyzed and evaluated, and applicable conditions of the method in application are expounded.
