城市隧道路段驾驶行为综合风险研究.

The illumination of the entrance and exit sections of urban tunnels varies greatly,and the internal environment is monotonous,which has a significant impact on driving behavior. This paper intends to study the comprehensive risk factors of the driving behavior of the urban tunnel section in order to reduce the risk of driving behavior and improve the safety of urban tunnel traffic. The comprehensive risk of driving behavior in the urban tunnel section mainly comes from two aspects. The subjective risk refers to the drive’s own conditions such as the psychological load of the driver’s life,the driver’s risk cognition level,and the objective risk refers to road environmental conditions such as tunnel lighting conditions,road route shape,and traffic flow. In this paper,risk analysis and decision theory are introduced to model the risk degree function of the factors that make up the risk of driving behavior decision,and to explore the quantitative research method of comprehensive risk of driving behavior in urban tunnel section. Taking the basic data of three urban tunnels in a city as an example,the model is used to calculate the comprehensive risk value of driving behavior. The results show that the annual statistical accident number of tunnel B with higher comprehensive risk value of driving behavior is significantly higher than that of tunnel A and tunnel C. The accuracy and applicability of the model are verified. [ABSTRACT FROM AUTHOR]
