How do you push forward a hit-and-run case with no witnesses, no surveillance camera, basically nothing to help at all. The traffic police come up with a brilliant way to solve this problem—using surveillance drones to record the crime scene and track the suspect.
Recently, a hit-and-run case occurred at a certain intersection, killing one person. After the local traffic police arrived at the scene, they found that there were no monitoring facilities and witnesses at the scene. According to the wreckage of the vehicle left at the scene of the crime, the police judged that the vehicle causing the accident was white pickup truck, and the front and reflector on the right side were damaged. At the stage of epidemic prevention and control, only one exit was reserved in the local area. The police quickly made a judgment that the accident vehicle was still in the Orchard Village, which was highly likely to be investigated as soon as possible.
However, the villages in Orchard Village have complex and intensive roads and large area of investigation. The investigation by traditional human means not only consumes a lot of police resources, but also is likely to “startle the snake”, leading to the absconding of suspects. To this end, the police decided to use unmanned aerial vehicles to cooperate with the surface personnel to conduct a inch-by-inch search of 1 kilometer around the local area.
The police screened all the surrounding white vehicles from the aerial perspective of unmanned aerial vehicles. Through high zoom, check whether the right front and reflector of the vehicle are damaged. Once suspicious targets are found, UAV operators immediately notify surface personnel to follow up and confirm.
After 30 minutes of intense search, the police found 20 suspected vehicles through unmanned aerial vehicles, with a search area of 5 square kilometers, and found the vehicle in the courtyard of the private house one kilometer east of the scene of the accident, then surface personnel arrived and detained the car.

In the end, the driver of the accident surrendered to the public security bureau under the strong pressure of the police and the persuasion of his family. So far, it was only 4 hours before the traffic police team received the report.
It is reported that many transportation departments and public security departments have fully launched the application of unmanned aerial vehicles. The scientific and technological power represented by unmanned aerial vehicles is becoming a strong support for improving the supervision ability and the level of scientific and technological governance. It is believed that unmanned aerial vehicles with strong flexibility, high timeliness, wide inspection scope and fast evidence collection will bring more application scenarios and imagination space for comprehensive urban management.
