Traffic flow dynamic guiding method based on region block

The invention discloses a traffic flow dynamic guiding method based on a region block. A vehicle-mounted terminal establishes communication connection with a cloud server; the vehicle-mounted terminalconducts data acquisition and uploads the collected data to the cloud server; the feedback of the cloud server is received by the vehicle-mounted terminal; the feedback includes the probability thatan accident of a current car occurs within the current road section setting range; after the vehicle-mounted terminal receives the probability that the accident of the current car occurs within the current road section setting range, the probability is sent to a driver through human-computer interaction; in the establishment of the region block relationship, the current vehicle-mounted terminal receives communication addresses, sent by the cloud server, of the surrounding vehicle-mounted terminals within the setting range, and the current vehicle-mounted terminal establishes the connection relationship with the surroun
