Well, the vehicles must be installed with these technologies. Detecting vehicles in white smoke and fog can use various technologies. Radar, using radio waves, is effective in low visibility, but it struggles to provide detailed information like the size or type of vehicle approaching. LiDAR, employing laser beams, creates a 3D map, offering specific details on size, shape, and position in challenging conditions. Although LiDAR is more expensive than radar, it excels in providing complete information about vehicles in adverse weather. Let me know in the comment section, how the accident due to white smoke and fog can be avoided.

Traditional vision systems struggle with low visibility conditions like white smoke and fog. Here are some latest technologies that can help detect vehicles in such conditions:
LiDAR (Light Detection and Ranging): LiDAR uses pulsed laser light to measure distance to objects. It creates a 3D point cloud of the environment, which can be effective in fog and smoke as it doesn’t rely on visible light.
Radar (Radio Detection and Ranging): Radar emits radio waves and detects their reflections from objects. It’s not as high-resolution as LiDAR but can penetrate fog and smoke well, providing information on a vehicle’s location and speed.
Thermal Cameras: These cameras capture heat signatures instead of visible light. Vehicles will show up as bright objects against the cooler background of fog or smoke.
Advanced Computer Vision Techniques: Machine learning algorithms are being developed to analyze camera images and identify vehicles even in low-visibility conditions. These algorithms can learn to recognize patterns in the data that humans might miss, such as headlights or taillights partially obscured by smoke.
Sensor Fusion: Combining data from multiple sensors like LiDAR, radar, cameras, and thermal imaging can provide a more robust and comprehensive picture of the environment. This allows for better vehicle detection even when individual sensors are hampered by smoke or fog.
These technologies are constantly evolving, and research is ongoing to improve their performance in challenging weather conditions.
