Study of expressways with heavy traffic flow during occupying-road construction

Abstract

In order to select the construction period of expressways with heavy traffic flow reasonably, this paper builds a mixed integer optimization model based on the in-depth analysis of various economic and social benefits and the constructional and organizational costs. Then the algorithm for the optimization model is studied and coded by Excel VBA. Finally, by the example of Ningbo-Taizhou-Wenzhou Expressway, the application method of the optimization model is demonstrated through concrete case analysis. The method proposed by this study can support the decision-making of the optimal allocation during the construction period of expressways with heavy traffic flow, and can effectively reduce the economic loss of expressway reconstruction or extension construction.
