Disclosed are a vehicle guidance method, apparatus, and system for a freeway. The method includes: responsive to a detection a driving speed of a vehicle in a monitored road section is less than a preset proportion of an average driving speed of the monitored road section, determining the vehicle that the driving speed thereof is less than the preset proportion of the average driving speed as an abnormal vehicle, and determining a lane in which the abnormal vehicle is located as an abnormal lane; determining, according to an average driving speed and a traffic density of each lane in the monitored road section, whether there is a congestion risk; responsive to a determination that there is the congestion risk, obtaining a respective guidance scheme of each vehicle in each lane; and sending the respective guidance scheme to each vehicle.

The present disclosure provides a road information correction method, apparatus, and system based on vehicle-to-everything (V2X). The method includes: sending a road information map to a first vehicle, such that the first vehicle obtains first original road information by using the road information map, and collects real-time road information; receiving the real-time road information uploaded by the first vehicle; determining, according to the real-time road information, whether the stored first original road information needs to be corrected; and if yes, correcting the stored first original road information according to the real-time road information; otherwise, not correcting the stored first original road information. According to the embodiments of the present disclosure, road information stored in a cloud can be corrected in a timely manner, and fast-changing information and slow-changing information can be identified to provide different determining mechanisms for the two, thereby ensuring precision of correcting road information.
