EU-China Joint V2X Trial Results

This article summarizes the main research and trial results of the 5G-DRIVE project. The European 5G-DRIVE and Chinese 5G Large-Scale Trial projects were twinning projects that aim to design Cellular Vehicle-to-Everything (C-V2X) assisted automated driving use cases and to trial out these use cases in the field experiments under a harmonized trial framework. One of the main objectives was to benchmark C-V2X connectivity between Europe and China. Evaluating the benefits of C-V2X connectivity at urban intersection use cases has been conducted. The main Key Performance Indicators include coverage range at the urban intersection, packet error rate and latencies which depends on antenna height and channel load. The comparison between long-range LTE/5G and short-range C-V2X/PC5 channels has been conducted. C-V2X provides low latencies (< 40 milliseconds in average) and coverage is less than 800 meters. LTE/5G supports longer ranges but it cannot guarantee latencies less than 70 milliseconds, which reduces safe driving speed to 30 km/h to keep the safety-margin at 0,6 meters.
