The results of accident reconstruction and in-depth
investigation are seriously influenced by the correctness and
completeness of accident data collection at the scene. In the
present, the tasks of accident investigation and data collection
at the scene are performed by the policemen, always resulting in
some data missing and mistaken measurements. The purpose of
this research is to develop a low-cost, time-saving, high
applicability, and high accuracy method for reconstructing the
accident scene to solve their drawbacks of the developed methods
which have been highlighted by the literature''s review. This
study employs an at-scene experiment method cooperated with the
computer graphical operation system thus developed to validate
the adquency of a so-called pseudo-maker setting method, and its
applicability was demonstrated by the case study on the actual
roadway. The pseudo-marker setting method is a newly single-
image photogrammetry method which is based on the geometrical
theory, and combines the theory of computer graphics to
reproduce the accident scene by the techniques of interactive
computer graphic and digital terrain simulation. In theory, it
partially solves the problems of how to determine the heights of
the imaged points on single-photos. In application, the
operational criteria for photographing the accident scene have
thus been proposed in cooperation with the developed method to
collect the accident scene data effectively. Employing the
developed method to collect the accident scene data not only can
preserve the correctness and completeness of accident data, but
also can solve the problems generally incurred in accident
investigation and data collection at the scene.
