A Review on the Safety Studies at Entrances and Exits of Expressway Interchanges
-
摘要: 高速公路互通式立交是保障高速公路正常运行的关键节点,而主线出入口是互通立交的重要组成部分,同时也是互通区交通流特性最为复杂的路段。国内外学者对互通式立交的安全性展开了较多研究,并取得了一系列成果,但由于互通式立交出入口的复杂性,相关研究并不系统。为此,以高速公路互通式立交以及高速公路出入口的安全性为主题进行文献分析,得到高速公路互通立交出入口安全性的研究热点,从几何设计指标、安全性评价方法以及运行速度3个方面对研究成果进行梳理与综合评述。研究结果表明:①我国现行规范对变速车道长度的考虑因素过于单一,与车辆实际运行中的变速距离需求不吻合;规范中对互通立交分合流端视距的规定,未针对车辆性能、驾驶人对道路交通环境的感知-反应时间进行优化;②目前对分合流鼻端的研究主要从二维角度开展,几何设计指标研究重点未聚焦于平纵指标的组合效果;③事故统计法、层次分析法以及模糊综合评价法在高速公路安全评价中应用较多,事故统计法可以客观的反映道路安全状态,但依赖于事故统计数据的准确性,层次分析法可以较好的构建安全性评价指标体系,但指标赋权较主观,使得评价结论不稳定,模糊综合评价方法对系统安全水平的准确评价依赖于隶属函数的选择,对研究人员的专业性提出了较高的要求;④现行规范的线形协调性、连续性的评价标准以传统方法Δv85为基础,该方法假设基础与实际相悖,高估了道路的安全性能,针对不同车型在不同出入口形式的运行速度预测模型有待深入研究。得到针对相关研究的建议与展望如下:①变速车道研究可以基于驾驶行为,优先考虑对变速车道上加速度变化趋势进行研究;②出入口视距研究应考虑复杂道路条件、视觉刺激下的反应时间,结合不同车型的车辆特性展开研究;在事故统计方法、预测模型基础上,可结合出入口特点进一步优化,并用相对成熟的安全评价方法进行检验;③出入口处的运行速度研究可考虑以浮动车辆数据(floating vehicle data,FCD)为主,龙门架及雷达测速数据为辅对车辆实际行驶速度变化过程进行研究。Abstract: Interchanges of expressways are critical nodes for traffic operation, and their entrances/exits are key components and show most complex traffic flow behaviors. Researchers have conducted numerous safety studies on interchanges and obtained a variety of conclusions, but their studies are not systematic due to the complexity of interchanges and the entrances/exits. To this end, this paper looks into the literature on the safety of interchanges and entrances/exits of expressways, identifies corresponding research topics of interest, and reviews corresponding findings in three areas: geometric design index, safety evaluation method and operation speed. Study results indicate that: ①The number of factors considered during the design of speed-change lanes in the existing standards in China is not enough to match the required distance for speed change from the field. The criterion of sight distance at the merging end of an interchange is not optimized based on vehicle performance and drivers' perception-reaction time to different traffic scenarios. ②Studies in the literature on the merging nose are mainly carried out from a two-dimensional perspective, and the geometric design factors are not focused on the effect of the combination of flat and longitudinal factors. ③The accident statistics method, analytic hierarchy process, and fuzzy comprehensive evaluation method are most commonly used in evaluating the safety of expressways. The accident statistics method can objectively be used to evaluate the safety, but it is dependent on the accuracy of accident statistics; the analytic hierarchy process can be used to develop safety evaluation indexes, but the weights associated to the indexes are often subjectively determined, which often makes the results useless; the fuzzy comprehensive evaluation method relies on the selection of the affiliation function to ensure a good accuracy of the evaluation of the level of safety, which places high requirements on the knowledge of the user. ④The evaluation criteria of coordination and continuity of road alignment in the existing standards are based on the traditional method Δv85, whose basis is contrary to the reality leading to overestimating the safety performance of the road. Therefore, speed prediction models for different vehicles in different entrances/exits should be studied in depth. From these results, the suggestions for the future works are as follows: ①Studies on speed-change lanes can be based on driving behavior, with a focus on the analysis of acceleration patterns over speed-change lanes. ②Studies on sight distance at entrances/exits should take into account complex traffic circumstances, drivers' reaction time under visual stimuli and characteristics of vehicles. Further optimization can be conducted based on the unique characteristics of entrances/exits, and tested with relatively mature safety evaluation methods, such as accident statistics methods and prediction models. ③In terms of the operating speed at entrances/exits, floating vehicle data (FCD) can be used together with the data from gantry cranes and radars to study the process that vehicles change their speed.
