碩士 === 逢甲大學 === 交通工程與管理所 === 93 === Due to the economic growth and the income increasing, the private vehicles are increasing simultaneously. In the meanwhile, the existed road capacity can’t fit the growth of vehicles. Therefore, the number of traffic accidents will still maintain in the higher level. Besides, the cases within each local traffic accident authentication are also increasing yearly. Under the limitation of manpower and the existed authentication system, it is almost impossible to improve the quality of the authentication cases. Therefore, this study will utilize the 3D simulation software to reconstruct the accident occurrence and to distinguish the accident liability. This study uses the PC-Crash simulation software to reconstruct the accident scenes drawing. Then, the courts or authorities can apply these accidents reconstruction as the major evident. However, the vehicle database is based on the European vehicles, so that it may not suitable for the requirements in Taiwan area. Therefore, this study will construct the vehicle database in which can be used in Taiwan area. In the accident authentication aspect, we will use the vehicle fundamental database in the real cases for simulation and analysis, and then compare the results of simulation with the practical cases. Furthermore, we will evaluate the capacity of PC-Crash software. In the reconstruction of accident scene aspect, we can use the PC-Rect in which is attached within the PC-Crash software, and then compare the recovered distances to the distance by the practical measurement. Also the study will select different location, vehicles, and types of accidents for simulation. Furthermore, this study will use “the Traffic Accident Fast system（TAFS）”developed by Jilin University to validate the reliability of PC-Crash. In the same time, this study will select six circumstances for three-cars-collision. Hopefully, we can simulate the collision, and then estimate the velocity of vehicles before collision. Besides, this study also use the real cases delivered by courts to reconstruct the accident scene, and then evaluate the advantages and limitations of the PC-Crash software. In the overall, use the PC-Crash software will increase the quality and credibility of accident authentication.
