In the world of traffic crash investigation and collision reconstruction, road closure time is a big deal. The longer traffic is disrupted the more chance of secondary collisions and more work to do. One of the ways to reduce the time it takes to clean up the mess is to carry mapping instruments in units and have them ready to go. Responding to the scene directly eliminates the need to return to the office to get equipment before responding. With this need in mind, Trimble built a Public Safety and Forensics GNSS mapping system called the Quick Response Solution (QRS).
