Attribute Theory-based Evaluation of Highway Construction Projects for Sustainable Development

In the background of scientific concept of development and sustainable development, while measuring the sustainability of highway construction projects, we should not only evaluate them in terms of the project objectives, but also make a comprehensive evaluation of its sustainability standing height of sustainable development. This article builds a comprehensive evaluation index system for sustainable development of highway construction projects based on the attribute comprehensive evaluation theory and also studies the dimensionless index of the method and method for determining the index weight, and finally verifies with examples.
