Traffic Accident Reconstruction Technology Research

Abstract

Based on the virtual simulation theory, we used three-dimensional modeling software to build modeling road facilities (vehicles, trees, street lights, etc.) for simulating the accident environment, and by using OpenGL technology, achieved reading, displaying and controlling the three-dimensional models. This dynamically realized the three-dimensional animated simulation of vehicle movement. Simultaneously we have calculated in progress the simulation of vehicle crash with the basic theory of automobile collision, vehicle collision model and the law of conservation of energy and momentum. Finally, we constructed a flexible platform for the simulation experiment. The platform is enabling to add and update road, trees, street lamps and house on the simulation environment dynamically, and has ability to analysis the traffic accident. This could give an assistant to the handling traffic accidents.

Methodology Designed to Evaluate Accidents at Intersection Crossings with Respect to Forensic Purposes and Transport Sustainability

“…Until relatively recently, the experts were limited by the absence of any recording devices within the systems used for traffic signal phasing and timing. Accident reconstruction methods have long relied on the generalized signal phasing and timings programmed for that intersection by the responsible jurisdiction, combined with the vehicle dynamics calculated for the collision sequence in conjunction with witness testimony regarding signal indications and phase changes [17,18]. Recent technological advancements in signal timing data collection, recording, and logging can provide engineers and experts with a new, time-specific, incident-relatable, and more robust method of analyzing signalized intersection collisions (in case the intersection is equipped with the signal timing data loggers).…”

“…Probably the most important aspect is the tenet three (traffic signal phasing and timing). Compared to the study [17], our methodology considers only the use of the static signal plan. Additional analyses of signal timing in real-time are needed for the dynamically controlled intersections (but when the traffic signal is determined the methodology is fully functional).…”
