Enhancing the deployment of vehicle-to-infrastructure (V2I) communications throughcomprehensive temporal approach.

Résumé

In the future, mobility will be connected, cooperative, and autonomous where self-driven vehicles will coexist together with human-driven ones, resulting in a safer and more efficient traffic flow leading to a reduction of CO2 emissions, life loss, and time spent on the road. That is why, in achieving the goal of having connected, cooperative, and autonomous mobility Vehicle-to-Everything (V2X) communications play a key role as they enable the communication between vehicles and between vehicles and the surrounding environment (infrastructure, pedestrians, etc.). Therefore, to lay the foundation for this future, there has been a great deal of progress in recent years to enable the exchange of information from the vehicles on the road to the infrastructure through Vehicle to Infrastructure (V2I) communications. For the envisioned future of connected, cooperative, and autonomous mobility to become a reality, V2I deployments are essential. They facilitate seamless mobility across highways and urban environments. However, the landscape of V2I communications is continuously evolving, with new features being introduced regularly. This dynamic nature necessitates ongoing updates and adaptations, precluding the possibility of a definitive, one-time deployment. Moreover, as V2I technology is still in the development phase, new deployments will be imperative to accommodate the advancements in this field. In this thesis, we show that the real deployment of V2I communications is improved when three stages of a V2I deployment (initial deployment, enhancement, and future perspectives) are considered. In the context of this research work the three stages are: • Initial deployment: The establishment of infrastructure is crucial for facilitating V2I communications. This foundational phase significantly enhances the initial deployment of V2I communications during the earliest field installations. Decisions made during this critical stage have a lasting impact on the entire lifespan of the deployment, setting the groundwork for future scalability and effectiveness. Given that the initial installation cost is substantial, relocating the components from their original deployment positions incurs significant expenses. Enhancement: Ongoing supervision of the installed facility is paramount for integrating new features effectively. It is highly advisable to rigorously test these features before their field implementation to ensure minimal errors. This proactive approach guarantees the reliability and efficiency of the system as it evolves. • Future perspectives: Finally, all the acquired knowledge and experience assist when engineering new V2I designs and features.
