The type of ramps of interchange in urban road network is an essential preliminary work in interchange constructing.Different type of interchange will invole various traffic function,investment,landspace and so on.So in this paper,Rough Set Theory is used to determine the interchange type of relative interchanges.A modle of interchange type selection is built via the evaluation for different design decision in the same network conditions.Indexes are screened out by the Rough Set Theory on the consideration of specific problems.This method avoids the traditional subjective evaluation method on determine the subjective membership index in AHP method.At last,an example is advised to solve the Rough Set model mentioned above.
