[0058] 1. Collection and sharing of vehicle data information;
[0059] Each vehicle obtains historical trajectory data and relevant contextual information from its own message logs, sensor units (such as GPS positioning sensors, motion sensors, etc.), including information such as vehicle speed, acceleration, direction, and location. After the vehicle information collection is completed, a broadcast scheme is used to share its mobility information. Each vehicle collects mobility information from neighboring vehicles, and at the same time collects numerous information related to vehicle communication status, such as broadcast rate, transmission delay, etc.
[0060] 2. Extract features from the collected information, standardize the proposed features, and standardize the authenticity labels of messages with two-dimensional vectors;
[0061] In this stage, based on the information collected in the previous stage, the following six important features about the vehicle (including v...
