METHOD OF AUTONOMOUS LANE IDENTIFICATION FOR A MULTILANE VEHICLE ROADWAY

摘要

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.
