The invention belongs to the field of unmanned driving, and provides a spatio-temporal data analysis design implementation method of an unmanned vehicle road network based on a software defined network, which comprises the following steps: step 1, related definition; step 2, an unmanned vehicle road network based on a software defined network; and step 3, a spatio-temporal data analysis algorithm of an unmanned vehicle road network based on a software defined network. The unmanned vehicle road network architecture based on software definition is used for managing road infrastructure and real-time vehicle state information exchange of the driving unmanned vehicles, calculating three traffic parameters of speed, occupancy rate and flow based on the vehicle state information, and obtaining the real-time vehicle state information of the unmanned vehicles through data anomaly detection and missing data complementation. And the reliability of the collected data is improved. According to the method, visual data set distribution is provided for solving the influence of unmanned low-speed driving on road traffic efficiency and safety in an urban scene, so that the method has important significance and application value for promoting healthy and rapid development of unmanned driving.
