Cellular network-based assisted driving method and traffic control unit

A cellular network-based assisted driving method, comprising:

• determining, by a traffic control unit (TCU), a first about-to-occur track of a first vehicle based on traveling status information of the first vehicle within a management range of the TCU, wherein the first about-to-occur track is a traveling track of the first vehicle that is to occur within a preset duration from a current moment, the first about-to-occur track comprising a first primary traveling track and at least one first secondary traveling track,
• assigning an occurrence probability to the first primary traveling track and an occurrence probability to the first secondary traveling track, wherein the occurrence probability of the first primary traveling track is greater than the occurrence probability of the first secondary traveling track;
• and
• sending, by the TCU, warning information to the first vehicle if the TCU determines that a second about-to-occur track of a second vehicle intersects the first about-to-occur track within the management range of the TCU, wherein 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, and the second about-to-occur track of the second vehicle is determined by using traveling status information of the second vehicle.
