[0035] A three-dimensional simulation method of traffic accidents based on VISSIM, which is characterized in that it is a new method for three-dimensional simulation of traffic accidents, based on the classic traffic simulation software VISSIM, supplemented by the secondary programming of COM interface; The overall technical route of VISSIM is that VISSIM has an interface that allows users to carry out secondary programming development. Through this interface, the objects of VISSIM can be controlled more deeply from the bottom layer, thereby realizing user-defined actions and movements. mode; it cannot generate a 3D element that did not exist before, and needs to use other tools to build a 3D model of static objects in advance; VISSIM can recognize 3D models in .v3d and .skp formats, which are produced by SketchUP and V3DM software respectively; like figure 1 As shown, based on VISSIM, supplemented by SketchUP and V3DM, a schematic diagram of the overall technical route of tra...
