Evaluation of Consumer Grade Unmanned Aircraft Systems for Photogrammetric Crash Scene Documentation

摘要

Public safety officials often institute road closures in the event of major vehicle crashes in order to provide a safe environment in which to document the crash scene. However, interstate closures result in unexpected congestion that may cause secondary crashes. A study of interstate crashes in Indiana, USA found that of the approximately 15,000 crashes in 2014, 3,448 occurred during congested conditions. The study found that the crash rate during congested conditions was approximately 24 times greater than during uncongested conditions.
