【摘要】 近年来,由于我国交通系统不够完善等因素,在高速公路上出现的交通事故也愈发增多,其中以二次交通事故带来的危害最大。通过问卷调查、资料查询等途径,深度分析出导致高速二次交通事故发生的主要成因,并对此建立一套较为完整的高速公路二次交通事故的智能预防系统,其中终端显示系统以GIS地图方式直观反映到各种显示端,使高速公路上其他车辆全方位获得事故信息,制定预防措施,有效地降低高速公路二次交通事故的发生,具有较大的现实意义。更多还原

【Abstract】 In recent years,due to the imperfect traffic system and other factors,there are more and more traffic accidents on the expressway,among which the second traffic accident is the most harmful.Through questionnaire survey,data query and other ways,the paper analyzes the main causes of secondary traffic accidents.A set of relatively complete intelligent prevention system for secondary traffic accidents of expressways is established,in which the terminal display system can directly reflect all kinds of display ends in the form of GIS map,so that other vehicles on expressways can obtain all-round accident information,formulate preventive measures,and effectively reduce the occurrence of secondary traffic accidents of expressways,which has great practical significance.更多还原
