Drones Used For Traffic Accident Scene Reconstruction

How to estimate the extent of damage at the scene of a traffic accident? Drones have become one of the high-tech products used by traffic law enforcement authorities. Drones are playing an increasingly important role in traffic accident scene reconstruction.

Why do we need traffic enforcement drones?

Through the high-altitude bird's-eye view of the drone and the camera equipment it carries, the situation at the scene of the traffic accident can be quickly and comprehensively recorded, and important data can be provided for investigation and reconstruction.

To determine faults after a traffic accident, authorities must collect extensive spatial information from the scene. Everything from the precise vehicle position to skid marks must be recorded and measured to provide accurate information about the nature of the collision for subsequent analysis and reference during legal proceedings that will take place months later.

While crucial, obtaining these tiny details can be time-consuming and, in many cases, dangerous. According to a study by the Virginia Transportation Research Council, every 2-3 minutes spent at the scene of an accident in a high-traffic area increases the likelihood of a secondary accident by 1 percentage point. This means that the longer the road is blocked to protect the scene of an accident, the higher the chance that pedestrians or people on the ground will be injured in another accident.


These hazards make it imperative for investigators to gather spatial information as quickly as possible to clear obstacles from the roadway faster and minimize time on scene.

Traditional methods require investigators to place tape measures and use digital cameras to record the scene, a process that can take up to six hours. Although modern investigators have begun using technology such as laser scanners and total stations to record distances and map sites, the process still takes two to three hours.

How do drones help reconstruct the scene of a traffic accident?

Traffic enforcement authorities have begun adding drone technology to their toolbox as urban development pushes road infrastructure and traffic congestion to breaking point and the number of traffic accidents is expected to increase.

Using drones, first responders are able to map a scene and collect all the data needed to build a comprehensive 3D model in just 15-20 minutes.

The technology means on-site personnel can save time and reduce risk, and the ability to build 3D models gives investigators the opportunity to analyze the scene from all angles and viewpoints during post-mortem inspections.

By adding RTK modules, drones can easily capture centimeter-accurate position data to ensure each 3D render accurately reflects the scene.
