Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication are essential for avoiding accidents, managing traffic, and ensuring the smooth flow of autonomous vehicles in urban environments. As 5G networks continue to expand, the potential for connected autonomous vehicles will grow exponentially.
4. High-Definition Mapping
Autonomous vehicles rely on high-definition (HD) maps to navigate complex environments. These maps provide detailed information about roadways, intersections, lane markings, and obstacles. While AVs use real-time sensors for navigation, HD maps are crucial for long-term planning and understanding the broader road network.
As AVs continue to evolve, HD maps will become increasingly detailed and accurate, allowing for more precise route planning and enhanced safety features.
