    Abstract: A high-accuracy positioning method and a corresponding positioning system and positioning terminal are provided, and may be used in the field of intelligent vehicle technologies. In this positioning method, a real-time kinematics (RTK) positioning technology and a multi-receiver constraint MRC positioning technology are used to determine a location of a to-be-positioned target. In this positioning method, an RTK error correction model and an MRC error correction model may be preconstructed according to a big data technology. The RTK error correction model is used to provide a correction value for an original detection value obtained based on the RTK positioning technology. The MRC error correction model is used to provide a correction value for an original detection value obtained based on the MRC positioning technology. Then, the correction values are used to calculate the location of the to-be-positioned target.

    Abstract: A cellular network-based assisted driving method and a traffic control unit are provided, to accurately assess a risk and provide a valuable safety warning for a vehicle. In various embodiment, a first about-to-occur track of a first vehicle is determined based on traveling status information of the first vehicle. The first about-to-occur track is a traveling track of the first vehicle that is to occur within preset duration from a current moment. Warning information can be sent to the first vehicle when it is determined that a second about-to-occur track of a second vehicle intersects the first about-to-occur track. The second about-to-occur track is a traveling track of the second vehicle that is to occur within the preset duration from the current moment.
