車輛油漆不同方向重複刮痕特性研析與鑑識

Abstract

車輛行車事故鑑定係以車輛行車事故現場偵查與鑑識技術為其基礎，因此致力於現場偵查之有效性、完整性，並鑑識技術之系統性有其必要性。行車事故車輛油漆片與刮痕鑑識屬車輛行車事故鑑定體系之重要一環，且不易獨立於其他鑑識技術，因而有待建立具有一般性及系統性之國內行車事故油漆刮痕走向與特性於肇事鑑定應用，此係一值得研究之課題。國內曾對於車輛油漆刮痕走向與特性進行分析研究，已提出單向刮痕走向與特性之研究成果，另外，亦發現汽車間特別存在有油漆不同方向重複刮痕之現象，不僅刮痕走向較為不易判別，過去也鮮少有相關參考文獻。汽機車間刮擦痕多半較不明顯，且大多於刮地過程中被磨去，不同方向重複刮痕之現象更為少見。因此，考量資料取得之難易度與實驗之危險性，本研究之研究對象以汽車間為主，不予考慮汽機車間之情形，而本研究將以單向刮痕走向與特性之研究成果為基礎，針對汽車間行車事故油漆刮痕走向及特性之研究課題，並以微觀觀點深入探討汽車間油漆不同方向重覆刮痕之現象。本研究並研擬當交通事故發生後，如何將油漆刮痕特性應用於事故鑑識之流程，將可供行車事故鑑定之重要參考依據。

It is based on scene inspection of an accident and the technology of investigation to investigate the traffic accident. Hence, it is necessary to strive for the effectiveness, completeness of scene inspect and the systematicness of the investigation technology. The pieces of paint and scrape of vehicles in accidents are the important things of investigation technology, and hard to discriminate from other investigation technology. It is a topic worth to study to build scratch direction and characteristics on investigation with generalization and systematicness. We have analysed and studied the scratch direction and characteristics of vehicle painting, and present the outcome. We also found that there existed repeat scratches with vehicle-vehicle particularly. It is not only harder to determine the direction but less reference about this. Scratches with motorcycle-vehicle are unapparent and generally rubbed off. Repeat scratch is more rare. Because of thinking about the degree of difficulty and the danger to get data, this study focus on vehicle-vehicle without considering motorcycle-vehicle. This study will be based on the results of the study of single scratch characteristics and direction of car painting with the topic of scratch direction and characteristics to discuss and research the phenomena of repeat scratches by microviewpoint. The study will draw up the procedure of how to use scratch characteristic in investigation after an accident was happened. The result could be the important reference of investigation.
