摘　　要：针对目前我国高速公路2次事故多发的特点,从初次交通事故交通流辐射分析入手,阐述高速公路交通事故影响范围和影响时间的分析方法。建立基于TransModeler微观交通仿真平台的交通事故辐射分析模型,对其中一种紧急事件的交通流辐射范围进行实例分析。本模型可为交通事故或其他突发事件的信息发布、预警提供信息与决策支持,从而达到减少2次事故发生的目的。Aiming at features of frequent secondary accidents on expressways in our country at present and starting from coverage analysis for traffic flow after the primary traffic accidents, this paper expatiates analysis methods for influencing range and time of traffic accidents on expressways. The paper establishes an analytical model for coverage of traffic accidents based on TransModeler, a micro traffic simulation platform, to perform example analysis for coverage of traffic flow of one emergency accident. This model can provide information and decision making support for issue of information and warning in advance of traffic accidents or other emergency events so as to reach the purpose of reducing occurrence of secondary accidents.
