The invention relates to a non-signalized intersection formation traffic control system and method under mixed traffic flow, and the system comprises a roadside communication unit which is used for collecting a BSM message broadcasted by a vehicle-mounted device in real time, receiving an optimal traffic strategy, and broadcasting the optimal traffic strategy to surrounding vehicles, thereby achieving the intelligent guidance of each vehicle; the edge calculation unit is used for receiving BSM messages of vehicles, performing map matching in combination with roadside sensing target information, grouping according to lanes according to a matching result, realizing dynamic formation, performing ordered management and control on the formation by adopting a vehicle team marshalling mode without conflict intention, further obtaining an optimal decision sequence through a Monte Carlo tree algorithm, and sending the optimal decision sequence to the road side sensing target. An optimal passing strategy is generated to realize sequential passing of the formation; and the vehicle-mounted equipment is used for broadcasting the BSM message to the roadside communication unit, receiving the broadcast message to extract the optimal passing strategy, and reporting the optimal passing strategy to a vehicle-mounted terminal display system, so that the optimal passing strategy is presented in real time through a terminal to provide intelligent driving guidance for a driver.
