高速公路上已经安装了减速标志，作为对超速的感知对策。然而，很少有人知道的道路标记的形状和间隔对行驶速度和车道位置的影响。采用驾驶模拟器试验和问卷调查相结合的方法，探讨减速标线模式对行车速度、车道位置标准差（SDLP）、驾驶员主观感受、心理负荷和视觉注意力的影响。39名参与者在模拟的双车道乡村公路上驾驶，在水平曲线处呈现不同形状和间隔的减速标记。路面标记与减少油门值和平均速度提前的水平曲线。标记形状并不影响参与者的速度选择或SDLP。减速标记的认知警示效应占主导地位，因为与具有恒定间隔的标记相比，参与者在朝向行驶方向具有收敛间隔的标记的情况下并没有更慢地驾驶。关于驾驶员注意力的问卷调查反映了道路标记对驾驶员车道位置维护的潜在用途。由于不到18%的参与者注意到标记间隔的收敛，减速标记也可能引起加速的知觉错觉。
Speed reduction markings have been installed on highways as perceptual countermeasures for speeding. However, little is known about the effects of the shape and interval of road markings on driving speed and lane position. In this paper, a driving simulator experiment and questionnaires were performed to explore the effects of speed reduction marking patterns on driving speed and standard deviation of lane position (SDLP), as well as drivers’ subjective feelings, mental workload, and visual attention. Thirty-nine participants drove on a simulated two-lane rural highway where speed reduction markings with different shapes and intervals were presented at horizontal curves. The pavement markings were associated with reduced throttle values and mean speed in advance of a horizontal curve. The marking shape did not affect participants’ speed choice or SDLP. A cognitive alerting effect of the speed reduction markings was dominant because the participants did not drive more slowly with the markings with converging intervals toward the traveling direction compared to those with a constant interval. A questionnaire on drivers’ attention reflected a potential use of road markings for drivers’ lane-position maintenance. Since less than 18 % of the participants noticed the convergence in marking intervals, speed reduction markings may also induce the perceptual illusion of acceleration.
