The objective of this paper is to test the effectiveness of speed reduction markings (SRMs). The empirical data including vehicle operations and drivers' psychological and physical reactions were collected in a driving simulator. An index-the relative speed difference-was developed to evaluate the effectiveness of speed reduction markings. Researchers analyzed data to test the effectiveness of speed reduction markings and quantitatively study their effects and the deceleration process. Out of 15 subjects, there were 1 (7%), 2 (13%), and 7 (47%) subjects who decelerated while driving through the downhill section in the No SRMs scenario, Longitudinal SRMs scenario and Transverse SRMs scenario, respectively. In terms of speed and subjects' decelerating maneuver, the results of the analysis of variance (ANOVA) and the contrast analysis (S-N-K method) showed that transverse speed reduction markings (TSRMs) could significantly influence subjects' speed choice and maneuver (P<0.05).
本文旨在测试减速标记（SRM）的有效性。在驾驶模拟器中收集了包括车辆运行和驾驶员心理及生理反应在内的经验数据。开发了一个指标——相对速度差——来评估减速标记的效果。研究人员分析数据以测试减速标记的有效性，并定量研究它们的效果和减速过程。在 15 名受试者中，分别有 1 名（7%）、2 名（13%）和 7 名（47%）受试者在无 SRM 场景、纵向 SRM 场景和横向 SRM 场景中下坡路段行驶时减速。从速度和受试者的减速操作来看，方差分析（ANOVA）和对比分析（S-N-K 法）的结果表明，横向减速标记（TSRM）可以显著影响受试者的速度选择和操作（P<0.05）。
