Presentation on technology and application validation of VRU protection services across three parts. Part 1 validates functional and process validation; Part 2 tests performance under low-density scenarios; Part 3 tests performance under high-density scenarios with three sub-scenarios: sensing multi-VRUs, multi-services concurrency, and multi-VRUs transmitting PSMs concurrently. Validation encompasses three communication approaches: vehicle-to-vehicle, infrastructure-to-vehicle, and vehicle-to-pedestrian, assessing protocol conformance, communication performance, sensing performance, and service logic triggering mechanisms.
