3D laser scanning for road safety and accident reconstruction

Pagounis, Vassilios ... [et al.]

The aim of traffic reconstruction is to recreate motor vehicle collision scenes in order to analyze the dynamics of the collision events, to provide evidence in court cases and allow the manufacturers to evaluate the vehiclees design. However, at the scene of the accident it is not known exactly the amount of information that will be required at the analysis and often relevant data are missing. The emergence of terrestrial laser scanning has enabled the 3D documentation of accident events in a safer way, as information can be collected without any lane closures or traffic interruptions, and in a more flexible and faster way, as a single user can operate the instrument in complete darkness or direct sunlight. The notion of this paper is to describe the use of terrestrial laser scanning for roadway and roadside data collection in intersection areas and extract geometric features for road safety analysis. Also emphasis is given on the qualitative assessment of condition classification road data obtained by terrestrial laser scanning and results are presented from a variety of data collected by a Leica HDS2500 laser scanner from simulated traffic accident scenarios.
