Abstract: A method is provided for identifying whether a vehicle has entered, departed, or stayed in a target lane as opposed to an adjacent non-target lane of a segmented roadway. Signals are received from at least one signal source at a receiver within, attached to or integrated into the vehicle marking the geographic position of the vehicle at a sampling rate in a detailed travel path. At each sampled point in the travel path, the method compares the standard perpendicular distance between: the vehicle and the target lane centerline (d1); and the vehicle and the non-target lane centerline (d2); It is assessed that the vehicle is in the target lane if the distance d1 is less than the distance d2, and otherwise, it is assessed that the vehicle is in the non-target lane.

Abstract: A method is provided for identifying a vehicle's lane of travel amongst a set of lanes in a roadway facility. This is needed for vehicle segregation management such as for lane-specific tolling or specified vehicle access. Signals are received from one or more signal sources at a receiver within, attached to or integrated into the vehicle. Using the received signals, an approximate path of travel of the vehicle is identified and it is determined whether the vehicle's approximate path of travel crosses a geofence or virtual gantry associated with at least one boundary region of the chargeable roadway facility. If the vehicle's approximate path of travel crosses the geofence, it is determined, using distance and speed measures, and with a calculated degree of certainty, whether the measured travel path is within the targeted lane of travel.
