A route deciding method, system, and device, and a medium. The method comprises: dividing the drivable road between the current position of a driverless vehicle and a destination into a plurality of waypoints; determining a target waypoint from among the waypoints between the current position of the driverless vehicle and the destination, and calculating the global cost from the target waypoint to the destination so as to obtain the waypoint value of the target waypoint; iteratively calculating the waypoint values of the waypoints between the target waypoint and the current position of the driverless vehicle according to the waypoint value of the target waypoint; and determining in real time the action at the current position according to the waypoint value of the next waypoint corresponding to the current position of the driverless vehicle so as to obtain the current route decision result on driving to the destination. The present invention improves the technical problem in existing techniques of low route decision efficiency due to model predictive control being used and complex optimization problems being solved in order to obtain the optimal route decision, and a large amount of computing power being necessary to solve non-linear optimization problems.
