Cooperative Awareness Messages’ Generation Frequencies, Trigger Distributions and Pseudonym Changes of First Commercially Deployed Vehicles in Real Operating Scenarios

Cooperative Intelligent Transport Systems have been deployed in mass-produced vehicles Europe (Golf 8, ID.3, etc.) since 2019, promising major improvements vehicle safety, efficiency, and comfort. Equipped with Vehicle-to-X communication, the directly send information about their driving status to environment. The data are already used for many communication use-cases specified by Car-2-Car Communication Consortium achieve above-mentioned improvements. This study focuses on using Vehicle-2-X its messages accident analysis. For this purpose, we investigated advantage temporal resolution of continuously sent Awareness Message compared Event-Data-Recorder reconstruction pre-crash. A high scene is essential doubtless clarification accidents. Therefore, analyzed generation frequencies trigger conditions available European market while real traffic during different parking maneuvers. Also, pseudonym change was analyzed. We found that average frequency higher than 2.00 Hz recording event recorder all scenarios investigated. Especially rural roads highways, advantageous. Since serious accidents occur roads, use Messages could significantly benefit scene. Thus, recommend increasing efforts as digital analysis encourage more scientists deal topic.
