Abstract: A quick investigation system in vehicle was developed to improve the technology and equipment
for investigation of road traffic accident scenes. The system is based on the binocular vision theory, using
photography research methods, while consisting of existing devices and real time remote audio equipment
in an investigate vehicle for road traffic accident scene. The system has two fixed focus industrial cameras,
control and display units, a connection platform and other accessories. Target distance measurements have a
precision of 1%. When using the system in an investigating vehicle, only one person is needed to maneuver with
the scale-free measurement of accident scenes accomplished without distance measurement pretreatment.
Therefore, the system can be applied to quick investigation of road traffic accident scenes.

Key words: road traffic safety, traffic accidents, traffic accident scene investigation, binocular vision, scalefree
measurement
