GNSS Innovation Provides New Quick Clearance Option for Collision Investigation

What’s the fastest, safest way to clear a scene after a collision and make sure you’ve captured all the data you need to conduct a thorough investigation?

Laser scanning is the standard best practice for fast, comprehensive data capture on any crime or crash scene. But not every agency has access to a laser scanner. Total station surveying equipment and photogrammetry are recognized for reducing crash investigation time for law enforcement officers compared to manual measurement and documentation approaches, and some agencies have done pioneering work with GNSS to increase accuracy and provide georeferencing. But each of these methods has drawbacks—most notably, the need for direct access to the site, which might not always be possible or advisable. And there’s always a need to go faster; with traffic incidents accounting for approximately one-quarter of all U.S roadway congestion, every minute counts. Faster incident clearance leads to happier motorists, a lower economic impact and reduced exposure of law enforcement personnel to hazardous roadside conditions.

A new GNSS innovation provides a solution. With the first-of-its-kind integration of GNSS, IMU (Inertial Measurement Unit) and a camera, the Leica GS18 I GNSS RTK rover enables you to measure with GNSS in areas where a view to the sky is obstructed or where the points themselves are inaccessible. You can capture images from a distance as you walk at a normal speed around the scene, and pull accurate discrete measurement points from the images while you’re on the scene or after you’re back in the office. This capability makes it possible to capture an entire collision scene in minutes and quickly verify that you have all the data you need.
