不同道路交通标志的服务功能和对驾驶员驾驶行为的影响是不同的。文章选择具有行为约束性的限速标志和警告标志,研究这两类交通标志对驾驶行为的影响机理。基于数值分析方法建立了限速标志影响下的速度选择模型,建立了警告交通标志影响下的驾驶行为模型,并用实测数据对模型进行了验证和分析。该研究成果有助于深入理解驾驶员在限速和警告交通标志影响下的驾驶行为特性,为交通标志的合理设计设置和交通安全行为的管制提供理论依据。
The service functions of the different road traffic signs are different from those of the driver’s driving behavior. The paper chooses behavioral restraint speed limit signs and warning signs to study the influence mechanism of these two types of traffic signs on driving behavior. The speed selection model under the influence of speed limit sign is established based on numerical analysis method. The driving behavior model under the warning traffic sign is established and the model is validated and analyzed with the measured data. The research results help to deeply understand the driving behavior of drivers under the influence of speed limit and warning traffic signs, and provide a theoretical basis for the reasonable design of traffic signs and the regulation of traffic safety behaviors.
