Traffic Volume Forecast for Expressway Expansion Projects Based on Python Improvement
Based on the traditional four-stage method,the current expressway segment OD is split by using Python in the traf-fic generation stage,and the accuracy of traffic volume forecast of expressway expansion project is improved from the first stage of the four-stage method.The method is applied to the expansion project of the Taicang-Changzhou section of the Shang-hai-Wuhan Expressway.Combined with the construction sequence of different river crossing passages,the annual traffic vol-ume of each feature of the road is predicted,and the segment OD of the long-term year is analyzed,which provides a basis for the formulation of expansion technology scheme and traffic organization.The results show that the method improves the fore-cast accuracy of the expressway expansion project,and has guiding significance for similar engineering schemes.
