高速公路交通事故与交通流量的定量关系分析

Quantitative relation analysis ofhighway traffic accidents and traffic flow

高速公路的交通事故预防研究是交通管理领域中的重要课题。通过具体分析事故发生前特定时间段的交通流量分布规律,统计交通流量中小型车和大型车等车型占比,建立交通流量计算模型,确定交通流量在事故高发时的阈值,通过高速公路实践验证结果的正确性,为今后高速公路精准控制交通流量,预防交通事故的发生提供了理论依据。

Prevention of traffic accidents on expressway is an important subject in the field of traffic management.This article analyzed a specific time period of the traffic flow distribution before accident,and the proportion of the small cars and large cars and other vehicles in traffic flow,and finally established a calculation model for traffic flow analysis to determine the threshold of traffic flow in a high incidence of accident.This model was verified in different highways,It provides a theoretical basis for preventing the happening of the highway traffic accident.
