    Abstract:

    According to the driving environment characteristic of the expressway tunnels,the concept of spatial visual pattern was proposed to analyze the driving behavior in tunnel section for the first time.On the basis of the definition and the assumed conditions,the influencing factors of spatial visual pattern were analyzed,and the critical conditions of tunnel spatial visual pattern were calculated from three aspects including horizontal curve,vertical curve and visual characteristic of the drivers.Based on the measured data,the driving behavior in tunnel section was different for different spatial visual patterns,the driving behavior process of the spatial visual pattern could be divided into two sections and the un-spatial visual pattern could be divided into three sections,and the operating speed process of the typical spatial visual patterns was validated.
