In traffic law enforcement cases, it is necessary for the authorities to collect a large amount of spatial information from the scene. Whether it is judging responsibility or assessing losses, it is necessary to ensure that effective and accurate information is extracted! This process is very time-consuming and complicated, and the introduction of enterprise drones will bring faster data collection capabilities.
Accurately recording and measuring data in traffic accidents is used to identify malfunctions after a traffic accident to provide accurate information on the nature of the crash for subsequent analysis and legal proceedings that may occur months later.
Complexity of On-Site Investigation of Traffic Accidents
In areas prone to traffic accidents, real-time monitoring is crucial, whether it is pre-investigation or post-event recording. The traditional data collection of accident sites is not only slow, but also very likely to cause road paralysis and secondary accidents!
According to a study by the Virginia Transportation Research Council, in high-traffic areas, for every 2-3 minutes of an accident scene, the likelihood of a secondary crash increases by 1 percent. This means that the longer roads are closed to protect an accident scene, the higher the likelihood that pedestrians or those at the scene will be injured in another accident.
These hazards make it imperative for investigators to gather spatial information as quickly as possible to clear roads, remove obstacles faster and minimize on-site dwell time.
Traditional methods require investigators to lay out tape measures and document the scene with digital cameras, a process that can itself take up to six hours. While modern investigators have begun using technologies such as laser scanners and total stations to record distances and map the scene, the process still takes two to three hours.
The Use of Corporate Drones in Accident Scene Reconstruction
And as urban growth pushes road infrastructure and traffic congestion to critical capacity, the number of traffic accidents is expected to increase, and traffic enforcement bureaus have begun adding drone technology to their toolkit.
Using a high-definition imaging drone, first responders are able to map a scene and gather all the data needed to build a comprehensive 3D model in as little as 15-20 minutes.
Using drones with RTK modules, law enforcement authorities can easily capture centimeter-accurate location data to ensure that every 3D rendering accurately reflects the scene.
The technology also means less time and less risk for field personnel, and the ability to build 3D models gives investigators the opportunity to analyze the scene from all angles and viewpoints during post-mortem inspections.
