Research On Evaluation Model For Landscape Coordination Of Mountain Highway Based On The Driver's Visual Psychological Characteristics

Recently,with the new concept of the road has been got more and more attention,the problem of people in harm ony with natu re is being more and more hot in the community.The function of transporting peopl e and goods has been unable to m eet the demand for roads,people care more about the traf fic safety and com fort of road.Mountain roads are usua lly specific location,it repu ires higher environm ental quality.Research on m ountain highway landsca pe coordination,not only reflects the harmony between man and nature and other c oncepts,but also promotes the upgrading of mountain highway traf fic safety level.In oreder to fi nd the lack fo the highway landscape coordination and provi de reference for im proving highway safety,this paper constructed mountain highway landscape evaluation system coordination.First,this paper analyzed systematically the p resent situation of the landscape design of roads and the highway landscape evaluation studies,and described the visual psychological characteristics of the driv er and landscape coordination theoretical foundation,including highway landsca pe concepts,along H ighway,Highway Landscape,ecology principles and mountain coordination related concepts.Through investigating and analyzing the m ountain highway landscape coordination of Nanfu Road and Shuangqing Road,summ arized landscape along the current situation and problems,including slope,retaining walls,d itches,structures,guardrails and village landscape.It provided the basis of constr ucting of m ountain highway landscape evaluation system coordination.Firstly,selected evaluating indicato r by tar get decomposition method.Followed,filtered evaluating indicator with expl oratory factor anslysis.Then,built structural equation modeling by confirmatory factor analysis and verified reliability and validity of the evaluation system.Established a m ountain highway landscape evaluation system coordination Including qualitative and qua ntitative indicators.The obtaining of quantitative indicators based on field measurements and combine research paper and the obtaining of qualitative indica tors based on exp ert survey.Then,the evaluation results need to be standardized.In order to inte gtate subjective weighting method and objective weighting method,and make the index we ight distribution m ore objective and reasonable,this paper used cloud model-anal ytic hierarchy process determ ining the mountain highway landscape coordination index weight.Finally,according to the actual situation of mountain highway,this paper established a co mbination evaluation model Mountain Highway coordination based on the deviation,the model can take advantage of various evaluation methods,im prove accuracy,reasonableness and feasibility of the evaluation results.In order to verify the reasonableness of mountain highway landscape coordination assessment model which this paper built,the paper used a combination of evaluation model based on the devi ation to evaluate a projects.The results showed the evaluation model has a certain rationality,accuracy and feasibility.
