Research On Highway Landscape Design Based On Driver’s Visual Sensitivity

With the rapid development of my country’s economy and society,the construction of expressways and their landscapes has gradually attracted people’s attention.As the "spatial chain" of urban development,expressway promotes the development of regional economy,but during the construction process,it will inevitably cause fragmentation of the landscape of the area it passes through,causing the original complete landscape to be fragmented into fragmented forms.Expressway landscape,as a long and narrow belt-shaped landscape space,can effectively darn and repair broken and fragmented regional styles,which is conducive to recreating regional styles.With the concept of "beautiful land" put forward in 2016,my country has paid more and more attention to the protection of national land and features and the restoration of the ecological environment.Since the northwest region occupies one-third of my country’s total area,it is an important part of the construction of my country’s land and features.Therefore,attention should be paid to the construction and protection of the landscape in the northwest region,which can be realized with the help of expressway landscape.When designing the expressway landscape,it should give full play to its linear landscape characteristics,and play a role in connecting and darning the fragmented and damaged landscape.At the same time,the expressway landscape can also bring a series of positive effects to the ecological environment of the area passed by.Therefore,the construction of expressway landscape is of great significance to urban development.This thesis studies the highway landscape design method from the perspective of drivers’ visual safety.Through the study of the existing research results,analyze the relationship between the highway landscape and the driver’s dynamic vision;through the combination of qualitative and quantitative methods and the application of mathematical models,visualize the highway space space based on the driver’s dynamic visual characteristics The sensitive area is divided,and the spatial scope of the high,medium and low visually sensitive areas is obtained;based on the results of the zoning,the landscape design methods of the three visually sensitive areas are explained separately.Due to the different nature of the three zones,the design focus is also different.Among them,the high visual sensitivity zone has the greatest impact on the driver’s vision,so the focus is on it.Through the principle of fuzzy analytic hierarchy process,the landscape components of the high visual sensitivity area are screened,and three highly sensitive factors are finally determined-slope landscape,central partition,and tunnel entrance landscape.The design of the three highly sensitive factors is discussed in detail method.Through the description of the landscape design methods of the three visually sensitive areas,we hope to form a set of highway landscape design methods that truly start from the perspective of driver’s visual safety,provide theoretical guidance for actual projects,and finally apply the design methods to the Linfa highway landscape In the design,it is aimed at improving the highway landscape quality and driving safety at the same time.
