Evaluation of profile edge markings as a road safety countermeasure: Analysis of crash statistics and on-road study of driver behaviour and attitudes

疲劳导致20%的致命车祸。轮廓线标记（PLM）旨在通过在驾驶员开始偏离道路时发出警报来减少与疲劳相关的撞车事故。澳大利亚每年都有大量的延伸，尽管对PLM的评估并不复杂或有缺陷。我们的目标是通过调查来提高对PLM影响的理解：1）关于PLM的信念/态度（例如“PLM损坏汽车”）; 2）道路边缘PLM是否增加了正面碰撞; 3）具有更宽间隔的“肋”的PLM的功效，有和没有单独的凸起的路面标记; 4）潜在的机制（例如，减少疲劳，增加夜间/潮湿时的能见度），以提高PLM使用的功效和效率。

Fatigue contributes to 20% of fatal car crashes. Profile line-marking (PLM) aims to reduce fatigue-related crashes by alerting drivers when they begin veering off the road. Substantial stretches are laid annually Australia-wide, although evaluations of PLM have been unsophisticated or flawed. We aim to improve understanding of PLM impacts by investigating: 1)beliefs/attitudes regarding PLM (e.g. "PLM damages cars"); 2)whether road-edge PLM increases head-on crashes; 3)the efficacy of PLM with more widely spaced "ribs", with and without separate raised pavement markers; 4)underlying mechanisms (e.g. reducing fatigue, increasing visibility during night/wet) in order to improve the efficacy and efficiency of PLM use.
