For large-area traffic management scenarios, traditional inspections are labor-intensive, slow, and unable to provide timely response or accurate evidence collection. Patrol efficiency is low, risks are high, and blind spots remain unmanaged. Using UAVs to monitor key areas such as “two stations and one yard” and expressways enables automated patrols and real-time traffic incident forensics, greatly improving operational efficiency.

For road survey and planning, drones replace manual GPS-based data collection with high-precision 3D modeling and orthophoto generation, providing accurate data for project design and implementation.
