Navigation route determination method and device and related product

The invention discloses a navigation route determination method and device and a related product. The method comprises the steps: determining a starting point lane where a starting point is located and a terminal point lane where a terminal point is located; according to the lane attribute data recorded by the lane-level road network data, determining lane weights of the starting point lane, the terminal point lane and a lane through which the vehicle passes from the starting point lane to the terminal point lane; based on the lane weights and the lane merging parameter threshold, determining the weight of a lane-level navigation route composed of the starting point lane, the terminal point lane and the passing lane; and based on the weight of the lane-level navigation route, obtaining an alternative lane-level navigation route pushed to the user. By adopting the scheme provided by the invention, lane-level navigation route planning can be carried out, and the planned navigation route is strong in rationality
