Rainvision: the impact of road markings on driver behaviour – wet night visibility
潮湿天气对驾驶员的影响

Previous European research, i.e. COST 331 and the IMPROVER projects had demonstrated that road markings greatly increase driver comfort during dry night time conditions. Nevertheless, they highlighted the need for additional research under wet and wet and rainy conditions.

Building upon this research, the RAINVISION project has investigated over the last three years how road markings can influence driver behaviour under all nightime weather conditions (dry, wet and wet and rainy) and how different age groups and gender groups adapt their behaviour based on the visibility and retro-reflectivity of road markings. The project has carried out three different trials; i.e. a simulation trial in France, a track test trial in Austria and on-road trial in the United Kingdom in cooperation with local authorities. For the simulation and track test trials, more than 100 test subjects were recruited respectively according to three age groups (20–40, 41–60 and 61+ years) and took several trials during different conditions. For the on-road trials, 10 highrisk sites were selected in cooperation with Durham county and Type II marking materials were applied in these sections. The project subsequently monitored speed over a whole climatic cycle and undertook an accidentology analysis. The results of the study in general indicate that the presence of enhanced road markings did significantly increase driver comfort, especially for older drivers. While there was an increase in driver speed, it was not seen as safety hazard as it was compensated by greater preview times. In fact in the UK trials, the results show that the presence of enhanced road markings actually led to a decrease in speeds.

先前的欧洲研究,i.e. COST 331 and the IMPROVER已经证明,道路标线在干燥的夜间条件下大大提高了驾驶员的舒适性。然而,他们强调了在潮湿和多雨的条件下进行深入研究的必要性。
 
在这项研究的基础上,RAINVISION项目在过去三年里调查了道路标线如何影响司机在晴雨天气条件下的行为(干、湿、湿和雨),以及不同年龄组和性别群体如何根据道路标线的可见度和回射率调整他们的行为。
该项目进行了三次不同的试验;即与地方当局合作,在法国进行模拟试验,在奥地利进行轨道试验,在英国进行公路试验。对于模拟和跟踪测试试验,根据三个年龄组(20-40岁、41-60岁和61岁以上)分别招募了100多名受试者,并在不同条件下进行了几次试验。在道路试验中,与达勒姆县合作选择了10个高风险地点,并在这些路段应用了第二类标记材料。该项目随后监测了整个气候周期的速度,并进行了事故学分析。研究结果总体上表明,增强的道路标线的存在确实显著提高了驾驶员的舒适性,尤其是对于老年驾驶员。虽然驾驶员的速度有所提高,但这并不被视为安全隐患,因为它通过更长的可视距离及反应时间得到了补偿。事实上,在英国的试验中,结果表明增强道路标线可视认性实际上导致了速度的降低。(在线翻译仅供参考)

Given that there is a correlation between a drivers perception of the road environment and road safety, it can be concluded that the more salient a marking material is perceived, the higher the subjective comfort and safety is experienced. 
Regarding driving behavior by means of speed choice (measured as lap times), test subjects drove slowest in the baseline condition, faster under condition with applied marking material I (dry reflective, type I), and slightly faster under condition with applied marking material II (wet reflective, type II). This result holds especially true for older persons like the subjects in the oldest age group in this study as an age interaction could be observed here. 
考虑到驾驶员对道路环境的感知和道路安全之间存在相关性,可以得出结论,对标记材料的感知越显著,主观舒适度和安全性就越高。
关于通过速度选择(以圈速测量)的驾驶行为,受试者在基线条件下驾驶最慢,在使用标记材料ⅰ(干反射型,1型)的条件下驾驶较快,在使用标记材料2(湿反射型,2型)的条件下驾驶稍快。这一结果对老年人尤其适用,如本研究中年龄最大的受试者,因为在这里可以观察到年龄相互作用。(在线翻译仅供参考)
