Study On The Driver’s Eye Movement And Psychological Characteristics And Its Application In Landscape Construction In Mountainous Freeway

Mountainous highway usually have the complex linear,more bridge and tunnel,frequent space conversion etc,which seriously affect the driver’s eye movement behavior and psychology.The highway landscape design is the lack of driver’s eye movement behavior and psychological characteristics into account,leading to the highway landscape viewing experience is not ideal,easy to cause the driver’s visual fatigue and boredom,which lead to traffic accident.Therefore,to study on the driver’s eye movement and psychological characteristics in the mountain highway,and the Countermeasures for the construction of the mountainous expressway landscape are discussed.,in order to the driver’s visual psychological needs.Based on the summary of driver’s dynamic visual characteristics and psychological reaction on the basis of relevant theories,combined with the experimental conditions to determine the index of the driver’s eye movement and psychological characteristics,the behavior of eye movement indicators: fixation duration,fixation times percentage,the percentage of fixation time,average fixation time,the psychological reaction index for GSR(GSR).Based on the real vehicle test,the driver’s eye movement and physiological index data were obtained,and the eye movement behavior and thus mental state of the driver in the mountainous highway were analyzed.On this basis,combined with the characteristics of mountainous highway environment,to discusses the Countermeasures of landscape construction.through this study: driver’s psychological state is generally open space than the shelter space is more intense,more psychological load.Right turn open road in three vertical space on the psychological load is much larger than the other linear road,and the depression angle is the Maximum.;in the linear test road,the driver’s fixation points focus on the front of the central region,in turn period of fixation will be offset to one side turn right away,the open section of the fixation point is more biased in the right side of the front;the straight section,fixation in angle space is the most divergent,most concentrated in the elevation space;linear test road in the segment,fixation duration is shorter,the cognitive load is small,the overall performance of the covered space look a long time than the open space;the driver on the straight road and the left road basically the same fixation characteristics to the region of interest in the three vertical space,and turn right at the three vertical space fixation characteristics to the region of interest there is a big difference in the linear section road of the driver;the average fixation time on the front of the central region of the longest,largest in cognitive load;short tunnel tunnel,the import and export of the psychological impact of small,long tunnel driver by import and export a greater impact,the effect of inlet than outlet section,and the second half of the long tunnel is prone to fatigue driving.It is clear that the connotation of landscape design of mountain freeway is to integrate and express all kinds of landscape resources in the road environment,to optimize the visual environment,to display the regional culture,and to ensure the safety of driving.Based on the investigation of the landscape resources along the mountainous highway,the concept of scenic spots is put forward based on the driver’s eye movement behavior and psychological state.From the three aspects of the value of the site,visibility and security to ensure the superiority of the scenic spots,to create the landscape point countermeasures.In the end,the author puts forward some countermeasures for landscape optimization.
