Research On The Setting Technology Of Anti-dazzle Facility For Highway

In recent decades,With the rapid development of China’s highway construction,the road traffic accidents attendant has serious crisis to beneficial to the people’s livelihood,The driver in the driving process mainly rely on visual access to traffic information around,and while driving at night,The sight condition is poor and the driver is easy to produce glare in the direct light of the headlights,The glare is a major factor affecting the driver’s vision at night,to eliminate or reduce glare phenomenon,anti dazzle facilities set in the central partition of the road.China’s current anti dazzle facilities set the spacing and height is the same,fixed,and different line sections have different requirements for anti dazzle,using a unified anti dazzle facilities height hidden danger of traffic safety,So from the view of traffic safety,It is necessary to carry out systematic and comprehensive research on the installation of anti dazzle facilities for highway.On the basis of the analysis of the physiological mechanism of visual production,the basic visual characteristics are studied,and the visual influence of glare on the driver is emphatically introduced.On the premise of analyzing the requirement of sight distance under different design speed,based on stopping sight distance,we set up the bias model of the anti dazzle facilities in the curve section,and calculate the maximum offset distance of the anti dazzle facilities for different types of vehicles on the overtaking lane of the curve.According to the antiglare plate spacing and shading angle and plate width relation establishment chart analysis of the relationship between the three separated,Through the establishment of the medial strip anti glare plant spacing calculation model,proposed different crown plant antidazzling spacing value of straight and flat curve under the most unfavorable conditions.Through research the anti dazzle facilities height on the flat slope,obtain the straight sections anti dazzle facilities height value of different motorcycle type of the most unfavorable Lane combination,and base on flat curve set ultra-high obtain ultra high section anti dazzle facilities height formula of computation,via the different vertical curve study on the setting height of anti dazzle facilities,obtain corresponding anti dazzle facilities height calculation model,and based on the existing research results,using computer programming technology to quickly get the entire road anti dazzle facilities height.This section analyzes two common engineering anti dazzle facilities,determines the situation of engineering anti dazzle facilities in different areas,and points out that we should pay attention to the landscape design of engineering anti dazzle facilities.Based on stimulation frequency and heart rate decreased experimental research,put forward a reasonable length of single green,and stipulate the color landscape color and set length,suggestions from the transformation form,increase plant species and increased flowering plants to central strip plant landscape for the corresponding optimization.
