V2X measurement on M0 motorway with 4 vehicles

V2X data collection under real world conditions.

Applicability of this dataset:

• V2X traffic analysis (for research and application development purposes)
• Comparison of unsecured and PKI-authenticated 802.11p-based V2X communication (ITS-G5)

Location: Hungary, Budapest + M0 motorway (ringroad around Budapest)

Date: 19th May 2023

Test participants:

• Budapest University of Technology and Economics
  • Faculty of Transportation Engineering and Vehicle Engineering
    • Department of Automotive Technologies - BME Automated Drive Lab
    • Department of Control for Transportation and Vehicle Systems - BME Traffic Lab
  • Faculty of Electrical Engineering and Informatics
    • Department Of Telecommunications and Media Informatics
• Microsec Ltd. (PKI provider)

Communication hardware: 4x Cohda Wireless MK5 OBUs (2 vehicles with PKI-on, 2 vehicles with PKI-off) with default settings

V2X stack : Cohda Wireless ETSI stack (Physical layer: ITS-G5)

Security stack: Microsec V2X PKI

Weather and road conditions: Clear and sunny weather, dry road

The datasets includes information on:

• Decoded received and transmitted V2X messages (secured and not secured GeoNetworking packets)
  • Rx.json – includes all received V2X messages by that specific host vehicle (CAM, DENM) also including RSU messages (CAM, DENM, MAPEM, SPaTEM, IVIM)
  • Tx.json – includes all transmitted V2X awareness messages by that specific host vehicle (CAM, DENM)
• Protocol stack (encapsulated in messages)
  • PHY layer (ITS-G5 parameters): channel number (CCH/SCH), MCS, Rx power, Rx noise
  • MAC layer: Ethernet header
  • Network layer: GeoNetworking header
  • Transport layer: Basic Transport Protocol (BTP)
  • Facilities layer: ETSI ITS (e.g. CAM, DENM etc.)

Measurement sections:

• Section 1 (Budapest -> M0)
• Section 2 (M0 motorway ring)
• Section 3 (M0 -> Budapest)
