摘要
施工围挡是道路施工区常用的交通安全设施,合理设置施工区围挡位置对保障施工区交通安全和节约施工区用地资源具有重要作用。以典型改扩建的高速公路为研究对象,利用驾驶模拟技术,在硬路肩有限的工作面内,设计3种外侧车道与施工围挡间距的模拟场景(0.5 m、0.75 m、1.0 m),组织开展40人的驾驶模拟对比试验,采集驾驶行为、眼动特性和生理信号等数据,采用配对t检验分析试验数据的可靠性,并提出由7项指标组成的评价指标体系,构建了基于熵权法的模糊综合评价模型,提出高速公路施工围挡位置熵权模糊综合评价方法,对3种高速公路施工围挡场景进行了比较分析和安全评价。结果表明:驾驶模拟器和试验场景均不会对试验造成不利影响;外侧车道与施工围挡间距为0.5 m的方案计算分值最高,综合响应表现最好。高速公路路侧施工围挡与外侧车道为0.5 m的距离,有效兼顾了节约用地范围和保障行车安全,可为科学设置高速公路施工围挡提供决策参考。
The work zone fence is a common traffic safety facility in the road construction area.The reasonable setting of work zone fence location plays an important role in ensuring traffic safety and saving land resources in the construction area.To this end,the paper took a typical freeway as the research object during the reconstruction and expansion.In the hard shoulder within limited working face fence spacing,the paper designed three kinds of the outside lane and construction simulation scenario(0.5 m,0.75 m,1.0 m),and carried out 40 people driving simulation experiments,and collected driving behavior,such as eye movement characteristics and physiological signal data.Then this paper used the paired t-test for analyzing the reliability of the experimental data and put forward the evaluation index system of 7 indicators and constructed a model of fuzzy comprehensive evaluation based on the entropy weight method.Thus we proposed the highway construction fence location entropy weight fuzzy comprehensive evaluation method.This paper carried out the comparative analysis and safety evaluation of three kinds of expressway construction enclosure scenes.The results show that neither the driving simulator nor the experimental scene has a negative effect on the experiment,which ensures the reliability of the experimental data.The paper established the membership degree relationship matrix of different evaluation grades and index value ranges,and the entropy-fuzzy comprehensive evaluation model was used to score.The scheme with the distance between the outer lane and the construction enclosure of 0.5 m has the highest calculated score and the best comprehensive response performance.The distance between the side construction fence and the outside lane of the expressway reconstruction and expansion is 0.5 m,which effectively takes into account the saving of land use range and the guarantee of driving safety and can provide a reference for the decision of setting the scientific construction fence of expressways.
