摘要 针对穿村镇路段交通事故多发的现状,利用面向对象Petri网(OOPN)作为建模工具,基于穿村镇路段现存的交通干扰类别及特性,构建作用于交通安全设施的事故推演模型,用以分析在穿村镇路段上各类安全设施对于事故发生过程产生的影响。利用该模型可定性分析各部分设施间的共同作用与事故发生间的关系,同时可利用已建模型计算某类设施的缺乏导致事故发生的概率,以定量分析各设施的重要度。研究结果表明,交叉口标志、支路上停车让行标志、限速标志以及人行横道标线为穿村镇路段优先考虑设置标志。 According to the current situation of frequent traffic accidents in highway segments passing through villages, this paper used the object-oriented petri net (OOPN) as the modeling tool, and based on the existing types and characteristics of traffic interference in highway segments passing through villages, constructed an accident deduction model for traffic safety facilities, which could be used to analyze the impact of various safety facilities on the accident occurrence process in highway segments passing through villages. On the one hand, the model could be used to qualitatively analyze the relationship between the interaction of various parts of facilities and the occurrence of accidents. On the other hand, the model could also be used to calculate the probability of accidents caused by the lack of a certain type of facilities, so as to quantitatively analyze the importance of facilities. The results of the study showed that intersection sign, stop sign, speed limit sign and pedestrian crossing were important signs that should be taken into consideration for the highway segments passing through villages.
