Environmental Impact Assessment of Highway: A new approach based on D numbers theory

Environmental impact assessment (EIA) is an important technique to ensure that possible effects of development projects have been fully identified and calculated for environment, and also its main purpose is accurate predicting, identifying and analyzing of all positive and negative impacts on the natural and human environment.Assessment of the environmental impact requires a method or methods to do it. Since the lack of sufficient knowledge, potential effects of projects are qualitative for nature, and they cannot been numerical exactly. One way to overcome this problem is using different types of uncertainty on EIA process. The theory of D numbers is a new provision of unreliable informationand it is developed version ofDempster-Shafer theory. In this research, an assessment of environmental impacts arising from the construction and operation of highways has been shown using D theory of numbers.
