摘要: 为深入研究雾天低能见度环境下驾驶人对可变限速(VSL)标志的遵从程度,首先设计问卷并对556名驾驶人进行访谈和调查;然后利用探索性因子分析选出影响驾驶人遵从程度的主要影响因子,包括驾驶人个人属性(年龄、驾龄)、驾驶人对限速的认可程度等;进而通过结构方程模型(SEM)确定主因子内部的各影响因素与遵从程度的相关性。结果表明:所建立的SEM与调查数据拟合程度良好;在雾天环境下,驾驶人对于VSL标志设定的限速认可程度都会在很大程度上影响其遵从程度;年龄、驾驶经验对驾驶人的遵从程度有显著影响;能见度较低时,行驶在车道数少的道路上驾驶人的遵从程度较高,而在能见度较高时,道路类型的影响不显著。

Abstract: To investigate the drivers' compliance with VSL signs under a reduced visibility condition, a survey was conducted into 556 drivers by means of questionnaire. The method of exploratory factor analysis was used to identify the main factors affecting drivers' compliance with VSL instructions, including driver personal factors, driver's satisfaction level at the signs etc. A structure equation model was built for the relationships between these factors and drivers' compliance. The results reveal that the SEM model effective, that drivers' satisfactions level at the signs is the most significant factor positively affecting drivers' compliance with VSL instructions under fog weather, that age and driving experience have a positively significant effect on drivers' compliance, and that driver's compliance would be higher when they drive on a two-land road, while the effect of road type is not significant under an improved visibility condition.

Key words: fog weather, reduced visibility, variable speed limit (VSL), degree of compliance, exploratory factor analysis, structure equation model (SEM)
