[Abstract]:Based on the matter-element analysis theory in extension theory and the entropy theory in information theory, a quantitative study on the intersecting scheme of urban expressway is carried out. Firstly, based on the analysis of the factors affecting the intersection scheme, the evaluation index system of the urban expressway interchange scheme is constructed. Secondly, by combining information entropy, correlation function and complex element, a complex element model for the evaluation of urban expressway intersection scheme is established. Thirdly, the complex element is calculated on the basis of determining the weight coefficient of the evaluation index by using the correlation entropy. Finally, an example is used to verify the validity of the model. The results show that the complex element model is simple and practical, and it can reflect the advantages and disadvantages of the intersection scheme of urban expressway.
