Example Embodiment

[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...

Abstract

The invention discloses a traffic accident three-dimensional simulation method based on microscopic traffic simulation software (VISSIM), and is a novel method for traffic accident three-dimensional simulation, uses a classical traffic simulation software VISSIM as a basic platform, and is achieved supplemented by a component object model (COM) interface secondary programming. The traffic accident three-dimensional simulation method based on the VISSIM supplies an overall technical route and a modeling method of main links, and comprises three-dimensional element model building, simulation system framework building, vehicle trajectory and process control, collision instant effect design and traffic environment design. The traffic accident three-dimensional simulation method based on the VISSIM has the advantages that the traffic accident three-dimensional simulation method based on the VISSIM greatly reduces workload, is large in flexibility ratio and low in technical difficulty, and is suitable for accident assessment mechanisms to accurately and rapidly achieve simulation of traffic accidents in low cost.

Description

technical field [0001] The invention relates to a method for three-dimensional simulation of traffic accidents, in particular to a method for three-dimensional simulation of traffic accidents based on VISSIM. Background technique [0002] In the process of analyzing and handling traffic accidents, relevant traffic police, parties, media, and the public often hope to have 3D simulation animations to show the whole process of the accident, so as to increase the persuasiveness and confidence of the accident analysis results. expressiveness. At present, the pure 3D animation production technology represented by 3DMAX can already produce similar animations, but this kind of method requires professional 3D production personnel on the one hand, and on the other hand, the production cycle is long and the production cost is high, so it is not suitable for the accident identification industry. Objective requirements of low cost and short cycle. Contents of the invention [0003] (...
