Given the inconsistent application of various road markings on Czech rural roads, there is a question “How does road marking in horizontal curves influence driving behaviour?” The study objective was to assess how centreline and edgelines influence driving behaviour. To focus on the critical conditions, six curves on secondary rural roads, with radii below 200 m, were selected and monitored before and after application of road marking. The studied indicators were average speed and lateral position, which were collected using trajectories detected in calibrated video recordings. The results indicated that speeds decreased in both edgeline and centreline applications; regarding lateral positions, the edgelines were associated with shifting the driving trajectories towards the centre of the road, and the centrelines were associated with shifting the driving trajectories towards the road edges. The indicated trends are likely to be influenced also by other factors, such as specific curve radii values, superelevation, speed profile, or parameters of road surroundings. Following study should thus focus on collecting data in a larger sample of sites and building a cross-sectional model, statistically linking the mentioned characteristics with safety.

水平曲线中的道路标记如何影响驾驶行为？

鉴于捷克乡村道路上各种道路标记的用法不一致，存在一个问题“水平曲线中的道路标记如何影响驾驶行为？” 研究目的是评估中心线和边缘线如何影响驾驶行为。为了关注关键条件，在道路标记应用之前和之后，选择并监测了半径在200 m以下的两条次要农村公路的曲线。研究的指标是平均速度和横向位置，它们是使用在校准视频记录中检测到的轨迹收集的。结果表明，在边缘线和中心线应用中速度均降低；关于横向位置，边缘线与将驾驶轨迹移向道路中心相关，中心线与将行驶轨迹移向道路边缘有关。所指示的趋势也可能会受到其他因素的影响，例如特定的曲线半径值，超高，速度分布或道路环境参数。因此，后续研究应着重于在更大的场所样本中收集数据并建立横截面模型，以统计方式将上述特征与安全性联系起来。
