The invention relates to the field of road engineering economy, in particular to a method for establishing an expressway reconstruction and extension opportunity decision model based on physical options. According to the particularity of the expressway reconstruction and extension project, the composite entity option of the expressway reconstruction and extension project is formed by selecting delay and expansion options, and then the closeness degree of the net present value and the composite entity option value is used as a design thought of a decision index. Compared with a traditional method, the conclusion obtained by using the method for establishing the highway reconstruction and extension opportunity decision model based on the entity options can give full play to the economic value of the highway reconstruction and extension project.
