Research on the Impact of Typical Sections in Urban Tunnel on Drivers' Psychology and Physiology

摘要

With the continuous development of the urban road network and a shortage of urban land resources, the construction of urban tunnels in China has rapidly increased in recent years, but the relative research of traffic safety in urban tunnels is still lacking. Considering the special driving environment of the urban tunnel, it's necessary to study the drivers' psychology and physiology in the urban tunnel to improve the traffic safety in it. In this paper, driving simulation experiments in the urban tunnel is carried out to explore the characteristics of drivers' visual function and heart rate. A quantitative method is used to study the impact of urban tunnel alignment on drivers' psychological and physiological characteristics, to provide a basis for urban tunnel alignment design and safety operation management. We analyze the vehicle speed, acceleration, as well as the psychological and physiological indexes and finally establish the linear regression models.
