A method for predicting lane error based on an identifier of a lane segment is disclosed. The method includes receiving a predicted location in a lane segment of a plurality lane segments for a first vehicle traveling on the lane segment. The method includes receiving a determined location of the first vehicle in the lane segment for the first vehicle. The method includes determining a difference between the predicted location in the lane segment received for the first vehicle and the determined location of the first vehicle in the lane segment. The method includes providing the determined difference between the predicted location in the lane segment received for the first vehicle and the determined location of the first vehicle in the lane segment and an identifier of the lane segment as first training data to a lane error estimation model.

System and method for estimating lane prediction errors for lane segments

In one embodiment, example systems and methods relate to a manner of providing lane curvature estimations. As vehicles travel, lane curvature estimates for lane segments as provided by the vehicle lane curvature estimation systems are collected. The estimated lane curvatures and the actual paths of the vehicles as they traveled in the lane segments are used as training data for a model that can both determine if a lane curvature estimate for a lane segment is likely incorrect and provide a correct lane curvature estimate. When a vehicle later travels such a lane segment, the model can be used to provide the vehicle with a correct lane curvature estimate. The correct estimate can be used by the vehicle in place of an estimate generated by the existing lane curvature estimation system of the vehicle.
