基于驾驶模拟器数据的因果关系分析，对道路直行车道接近缓和曲线路段设置减速标线的有效性进行了分析。本研究着眼于构成减速标线的横向标线的间距模式（称为阵列模式），假设在直线车道上实验设置的任意截止点之前，车辆的线性减速度在间距减小模式和间距恒定模式之间没有差异。通过使用面板数据进行差异中的差异分析，指出在截止点之后，两种比率之间存在显著差异。最后得出结论，当平曲线半径发生变化时，除驾驶员以接近曲线设计速度的速度接近曲线外，均需改变缩减间距模式。
Based on causality analysis using driving simulator data, this study analyzes the effectiveness of speed reduction markings installed in the straight lane approaching transition curve section on the road. Focusing on the spacing pattern of transverse marking lines constituting the speed reduction markings, which is referred to as an array pattern, this study assumes that linear deceleration rates of the vehicle before an arbitrary cutoff point placed experimentally on the straight lane do not differ between the reduced spacing pattern and constant spacing pattern. By performing a difference-in-differences analysis using panel data, it is pointed out that there is a significant difference between both rates after the cutoff point. Finally, it is concluded that the reduced spacing pattern needs to be changed when the horizontal curve radius changes, except in the case that drivers approaches the curve with the speed close to the design speed of the curve.
