Highway cost estimation system based on terrain

As in the case of known corridor belt,the highway construction cost is predicted,which helps to limit the implementation of the design. Based on nearly 10 years of highway construction projects in Fujian province,the ones which have a great impact on the cost of the project are extracted from each project,including pricing earthwork,engineering denominated stonework,protecting works,drainage works,bridge construction,tunnel construction and the corresponding terrain index parameters. SPSS is used to do the correlation analysis and analyzes the key indicators terrain which controls the five quantities. And the example shows that the model can predict effectively 5 quantities in different terrain conditions and reasonable value of the total cost,with high precision,easy to operate.
