Evaluation Method of Two-Lane Highway Green Landscape

Highway green landscape is an important part of the highway systems. Now freeway and multi-lane highway green landscape have been concerned, but two-lane highway green landscape has not been researched. Through analyzing the function of greening, this paper summarizes a research project that was to develop evaluation models for green landscape evaluation. The main evaluation indices considered are soil stability enhancement capability in slope embankment area, and environmental ecologic protection capability in roadside area. In addition, landscape scenic view quality is another important factor. The main purpose of the models is to convert evaluation indices to an overall quality measure, representing the overall quality of the second grade highway green landscape. The conversion is based on linear regression models and AHP method, basing on highway in Jiangsu. These models can be used to more objectively evaluate two-lane highway green landscape.
