Publication number: 20220237583Abstract: A toll advertisement message (TAM) broadcast from a roadside unit (RSU) is received by a vehicle via V2X communication, the TAM indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A heading of the vehicle is determined in relation to a TAM reference point indicating a geographic location of a toll gantry. A toll zone boundary region for the vehicle is identified by filtering the geographic locations of the lanes in the TAM to include only those lanes in a travel direction consistent with the heading. A lane straddling algorithm is utilized to identify, for each of the lanes in the travel direction, a respective percentage within each lane that the vehicle is traveling. A tolling usage message (TUM) is sent via the V2X communication, indicating to the RSU the percentage lane usage of the vehicle.Type: ApplicationFiled: January 26, 2021Publication date: July 28, 2022Inventors: Krishna BANDI, Sathyanarayana Chary PALAKONDA, Samer IBRAHIM, Brennan HAMILTON, Jovan Milivoje ZAGAJAC
