Utilization of Path History Data for the Extension of V2X Network Coverage

초록

This paper demonstrates the usefulness of the PathHistory element in the SAE J2735 standard. A real-world test was conducted, utilizing the PathHistory element to display the track of a vehicle over 680 meters away, outside the range of the C-V2X (Cellular Vehicle to Everything) units. By utilizing the latitude and longitude offsets provided in the data, a reconstructed path of the vehicle was generated, beyond the view of the C-V2X RSU (Roadside Unit). This data element has the potential to expand the RSU coverage range far beyond what antennas were capable of. Several use cases were presented that allow for the extended coverage of RSU placements and the detection of crash elements on the road.
