Abstract
PurposeGiven 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.MethodsTo 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.ResultsThe 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.ConclusionsThe 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.

4 Discussion and conclusions The study addressed the problem of inconsistent application of various road markings on Czech rural roads
It relates to the question: How does road marking in horizontal curves influence driving behaviour? The specific objective of the paper was to assess how centreline and edgelines influence driving behaviour
Summary
Horizontal road alignment is one of the general design features, which has a significant impact on driving and safety. Curves are places of special interest for their higher accident risk compared to straight alignment due to Another feature is road marking. It may be seen as a simplistic measure, it was found to be the most effective (i.e., with one of the highest cost-benefit ratios) low cost road safety treatment [11]. It consists mainly of longitudinal lines [12]: Havránek et al European Transport Research Review (2020) 12:33
