摘要 ：
道路交通安全设施的设置与驾驶员行车安全舒适性息息相关,如何合理有效地设置交通安全设施,对降低驾驶员行车安全风险至关重要。基于对交通安全设施设置原理和基本设置原则的分析,针对道路行车条件基本一致、分别依据中国和英国的交通安全设施相关设置规范的港珠澳大桥珠海口岸段与香港口岸段桥梁和隧道影响区域两个路段,进行对比分析,发现大陆段和香港段在交安设施设置方面存在一定差异。结果表明:对于交通标志,大陆段的版面图形和香港段的版面颜色设置更为合理,但香港段隧道入口前交通标志数量和版面信息过载;对于交通标线,大陆段隧道入口前设置的减速标线和红色路面铺装不符合交通安全需求和交通色彩要求;对于护栏,大陆段和香港段护...

摘要 ：
Objective Traffic safety is closely related to the driver's ability to obtain visual information. Low visibility would result in traffic accidents. This study aimed to explore the difference between meteorological visibility and traffic safety visual distance in foggy areas in the daytime, and analyze the difference between dynamic visual ability and static visual ability, so as to calculate the maximum acceptable speed limit that meets the driver's safety visual distance requirement. Methods Visual distances under different visibility conditions were collected for 12 passenger car drivers through static and naturalistic driving visual recognition experiments. The power function relation model between driver's static visual distance and meteorological visibility was established, and the attenuation rates of dynamic visual distance at different driving speeds were obtained. Results Traffic safety visual distance (TSVD) gradually grows with the increase of visibility and finally tends to be stable due to the vision limitation of the human eyes under good weather conditions. The drivers' visual ability decreased while driving dynamically, and dynamic TSVD was shorter than static TSVD. Conclusions Traditional meteorological visibility is different from drivers' actual TSVD, but there is a correlation between them. According to the relationship between visibility and dynamic TSVD, the maximum recommended speed limit values under different visibility levels are provided. The calculation of the maximum acceptable speeds under specific visibility conditions can provide a technical basis for road construction and traffic management.

为保证隧道内驾驶员对指路标志的安全视认,分析隧道照明光环境、标志特性对驾驶员视认距离的影响,营造了隧道中间段5种色温、3种亮度照明光环境,随机选取了20名小客车驾驶员进行半透发光式与逆反射式指路标志的视认试验.结果 表明:隧道内半透发光式指路标志的视认距离明显优于逆反射式指路标志,且半透发光式指路标志的最佳字体照度范围为3 000 ～3 500 lx;在最佳的背景光环境条件下,半透发光式指路标志与字高53 cm,笔画在5画以下、5～10画及10画以上的逆反射式指路标志达到相同的视认效果时,字高分别缩减了35.85％、30.19％和24.53％.半透发光式指路标志的应用可提高隧道内指路标志的视认距离,并能减少交通事故的发生,可为以后隧道内交通标志的改进与创新提供理论支撑.

摘要 ：
高速公路互通立交区道路、交通和行车环境条件的复杂程度远高于基本路段,是制约高速公路运行安全和通行效率的瓶颈路段.互通立交安全性评价研究虽取得了一系列成果,但离实际应用仍有一定差距,有必要对其研究现状进行回顾、总结与展望.为此,针对互通立交安全性评价研究进行系统梳理和总体框架搭建,将其具体分为人因工程理论、交通冲突理论、运行速度协调理论三大理论,事故统计法和层次分析法两大方法,并对其进行综合评述.研究结果表明:人因工程理论适用于主线和匝道的安全性评价,能更准确排查行车安全隐患点、段,但应考虑车辆类型和合理的试验样本量,提高评测指标的稳定性;交通冲突理论适用于主线上存在明显交通冲突区域的安全性评价,但未考虑道路条件对安全性的影响,且应进一步完善交通冲突评价指标体系、划分阈值以及分、合流形式的研究;运行速度协调理论较为成熟,已应用于高速公路基本路段的安全性评价,但主线和匝道的运行速度段落划分和预测模型精度均有待进一步提高;事故统计法的结论客观可靠,但事故数据统计和共享难度大,层次分析法可确定安全性评价的重点内容和关键影响因素,但评价结果主观性较强,2种方法的适用性均存在较大限制.未来研究应针对主线和匝道两大区域系统展开,评价对象应包括分流影响区、合流影响区和衔接过渡区三大路段,建议聚焦人因工程开展深入研究,以最小的代价创建符合人机功效学的互通立交安全运行环境条件.

摘要 ：
Prior safety evaluations of interchange merging areas have mostly focused on traffic conflicts and operating speeds, without considering how these factors can influence the driver workload. Researches regarding the level of driver workload have largely concentrated on urban roads, tunnel sections, and basic freeway segments, without considering the impact of merging traffic flows on safety. Therefore, this study has investigated how merging vehicles can impact through-driver workload and safety. Three independent field experiments were conducted on freeways, involving 18 drivers and 17 interchanges. The results showed that the vehicles merging onto freeway impact driver workload and driving performance, generating potential risk that cannot be ignored. Merging into the mainline traffic flow increases the through-driver workload to a higher level or even exceeds the safety threshold, despite there being better geometrical conditions of interchanges than those of basic freeway segments. When the volume of merging vehicles exceeds 564 pcu/h or the traffic saturation is above 0.485, driver workload rises above the safety thresholds and the driving risk is elevated, which potentially would lead to crashes. This study offers insights for more effective segment division of operating speed prediction, and dynamic risk management with regard to interchange safety.

摘要 ：
Traffic guide signs should be settled in a freeway tunnel when there is a short distance between the interchange exit ramp and the tunnel exit in order to provide enough reaction time for drivers. However, there is not enough space for guide sign in a tunnel adopting the same design method as the guide sign along the general segment of the freeway. The maximum dimension of a guide sign in tunnel should be studied firstly. Based on the analysis of the characteristics of the inner outline design of the tunnel and its relationship with the guide sign dimension, the study was classified into different combination conditions: left superelevation and right superelevation under two-, three-, or four-lane freeway tunnels, respectively. The essential elements, the horizontal and vertical clearances, the radius of the tunnel vault circles, the angle of the superelevation, and the allowance vertical dimension for future sign installation were all taken into account to establish the dimension model of the guide sign in the tunnel. The maximum dimensions of the guide signs were proposed under different combination conditions. The results indicated that there is only one set of the width and the height to obtain the maximum area of the guide sign in the freeway tunnel. The height of the guide sign reduces with the increase of its widths, and the area of the guide sign increases and then reduces with the increase of its width under the same grade of superelevation. The changing trend and extent of the dimension of the guide sign under left superelevation condition were different from those under right superelevation.

摘要 ：
The infrastructure, traffic, and driving environment at interchanges are considerably more complicated than those in basic freeway segments; interchanges are the bottleneck segments of freeways in terms of safety and efficiency. Although there has been a series of achievements in terms of safety evaluation of interchanges, issues remain between theoretical systems and practical applications. It is necessary to review the current literatures to lay the foundation for future research. This paper summarizes the framework of all researches on interchange safety evaluation. The evaluation works are based on three theories-ergonomic theory, traffic conflict theory, and consistent operating speed theory. The main evaluation methods are the crash statistical method and analytic hierarchy process method. For evaluation of the theory, ergonomic theory can be widely used to evaluate the safety of the mainline and the ramp. This accurately detects risky sites and segments; however, the tested vehicle types and sample sizes should be determined to improve the validity of the index results. Traffic conflict theory is applicable for assessing the mainline areas with obvious traffic conflicts, but the impact of road conditions on safety is not considered. The evaluation index and the corresponding thresholds under more forms of diverging and merging should be studied, respectively. Consistent operating speed theory is relatively mature to evaluate the safety condition of basic segments along freeways; however, the segment divisions and prediction models of operating speed on mainlines and ramps should be further optimized. In terms of the evaluation methods, the results of the crash statistical method are objective and reliable, but data collection and data sharing are difficult. The analytic hierarchy process method can determine the key factors for safety evaluation, but the results are partially subjective. Both evaluation methods have limitations. For further research, the safety evaluation for interchanges should be developed around both mainline and ramp systems, and the evaluation objects should consist of the diverging influence area, merging influence area, and the joint area. It is suggested that further research focus on human-factor engineering theory, and thus the cost-efficiency could be determined to establish a safe driving and operation environment for interchanges in line with ergonomics. © 2020, Editorial Department of China Journal of Highway and Transport.
