ESTIMATE METHOD FOR COST OF ROAD CONSTRUCTION

摘要

A method of estimating expenses for constructing road is provided to minimize error in the prediction of construction expenses by reflecting a unique characteristic of each construction. A plurality of indexes showing the characteristic of the road construction is set up. A case database including the index information of cases and construction expenses is built. A similarity point of each index is given to the index of the preexistence case. The weighted value and similarity score are applied to a plurality of indexes, and the similarity score of the preexistence case is calculated. After a plurality of preexistence cases is selected as the order where the similarity score is high, the average of the construction cost per unit length of the chosen preexistence case as described above is calculated. The road length of the predicted case multiplies the construction cost per unit length.
