Abstract
An RNSS-based lane-level vehicle tolling method and system for a roadway having at least one managed traffic lane and at least one unmanaged traffic lane, and on-vehicle equipment for use therein, overcome lane identification limitations of RNSS-based tolling and achieves lane-level tolling through explicit lane identification. In some embodiments, a vehicle transmits a lane presence indication (LPI) to indicate to off-vehicle toll processing whether the vehicle is currently in a managed or unmanaged traffic lane. In other embodiments, on-vehicle toll processing uses lane identification information locally to determine whether the vehicle is currently in a managed or unmanaged traffic lane.
