Safety Evaluation Of Highway Roadside Greening Landscape In Mountain Area And Research On Resonable Construction Model

Based on summarizing of highway landscape design and evaluation both in domestic and abroad by collecting and looking up document, the problems existed in the construction and evaluation of highway landscape in our country were analyzed. The research on evaluation index system of driving safety and construction model of roadside afforesting landscape was carried out for further. The research contents and results in this paper are mainly as follows:(1) The related concepts of highway, highway landscape and landscape evaluation were introduced briefly. From the point of driving comfortable and driving safety, the impact of roadside landscape on driving safety was analyzed. According to the principle of construction for evaluation system, an evaluation system for assessing the impact of roadside landscape of highway on driving safety was established. Through analysis and comparison on method for evaluation of landscape existed, the unascertained measure evaluation was introduced into the field of highway landscape evaluation. The method was described in detail. The evaluation results show that the unascertained measure method is reasonable and can be applied as a new way for highway landscape safety evaluation.(2) Experimental research was performed on the highway from Zhang jiajie to Sang zhi. According to comprehensive piecewise method, the highway from Zhang jiajie to Sang zhi was divided into eight sections where the experiment in real car was carried out. In order to get each index value, the heart rate was recorded, and the roadside landscape of each road section was photographed at the same time.(3)According to the system of evaluation which has been established, the weight of each evaluation index was confirmed by using the entropy method, the roadside greening landscape of each section was evaluated by using the unascertained measure evaluation method. The results showed that the section L8 was evaluated as middle grade, the other sections were considered as excellent grade. Then, the security level of each roadside landscape was sequenced, as follows:section 2
