Evaluation of Dynamic Landscape along Jiuzhi-Maerkang Expressway based on Digital Twin Scenario
The Jiuzhi-Maerkang(Jiu-Ma)Expressway,as a major channel connecting the northwest to the southwest of China,plays an important role in promoting local economic,social development and driving tourism.From the perspective of road users,a dynamic landscape evaluation study is carried out on 4 landscape sections along the Jiu-Ma Expressway,11 evaluation indexes are selected from landscape basement,landscape horizon,landscape nodes and other aspects to create a dynamic landscape evaluation model along the expressway with 3 levels of"plane-line-point".BIM+VR technology is used to build a digital twin scenario to simulate driving experience and evaluation,and AHP is used to determine the weight of dynamic landscape evaluation indicators and carry out fuzzy comprehensive evaluation of the landscape.The results show that different landscape sections along the Jiu-Ma Expressway bring different feelings to the road users.Among them,the dynamic landscape section with extreme high-quality is the Duomeihuayuan landscape section,the relative high-quality one was the Lyuxiahuagu landscape section,the Mijinghualang landscape section and the Hongyuanhuahai landscape section are ordinary quality,and there is no sections with low-quality.Objective assessment of each landscape section's quality along the Jiu-Ma Expressway can provide references for local relevant departments to guide the development of tourism along the expressway and landscape management,construction,development and decision-making.
