SYSTEMS AND METHODS FOR MITIGATING ANOMALIES IN LANE CHANGE DETECTION

System, methods, and other embodiments described herein relate to improving detection of lane changes for an ego vehicle. In one embodiment, a method includes, in response to detecting a surrounding vehicle from sensor data acquired about the surrounding environment by the ego vehicle, estimating a relative position of the surrounding vehicle in relation to the ego vehicle. The method includes determining a context of the surrounding vehicle in relation to a present roadway on which the ego vehicle is traveling. The method includes selectively grouping the surrounding vehicle into a change group according to the context. The change group including one or more vehicles for assessing movements of the ego vehicle. The method includes analyzing relative movements of vehicles in the change group to generate an indicator of whether the ego vehicle has performed a lane change.
