1. A navigation system comprising:
a communication unit including microelectronics configured to receive vehicle environment information of a user vehicle, the vehicle environment information including proximate vehicle information representing proximately located vehicles relative to the user vehicle; and
a control unit including a processor, coupled to the communication unit, configured to:
determine lane reference vehicles from the proximately located vehicles based on a vehicle type, which is general category or classification based on a shape, a size, and a profile, and a motion pattern, which is maneuvering of a vehicle over a period of time, of the proximately located vehicles;
monitor a relative location of the lane reference vehicles;
generate a road lane model including a lane delineation estimation based on the relative location of the lane reference vehicles;
calculate a lane position of the user vehicle according to the lane delineation estimation based on a lateral position shift of the user vehicle; and
operate the user vehicle to maintain or change the lane position according to the road lane model based on the lane reference vehicles during autonomous operation of the user vehicle.
