Research on evaluation of highway reconstruction and expansion traffic organization plan

With the rapid social and economic development in China, the highway mileage has increased from 104,400 kilometers in 2013 to 177,300 kilometers in 2022, with an average annual growth rate of 7% in the past 10 years. Those highways built earlier are aging and dilapidated and need to be renovated or expanded to accommodate the rapidly growing traffic demand. The reconstruction and expansion project will be an important part of future highway construction. A reasonable traffic organization is crucial during reconstruction and expansion, which will affect project implementation as well as social, economic and safety. This article analyzes the traffic organization plan for highway reconstruction and expansion, and chooses the fuzzy analytic hierarchy process (FAHP) to evaluate the traffic organization plan. After literature analysis, a preliminary evaluation index set was constructed, and the primary and secondary factor analysis method was used to construct an evaluation system for the highway reconstruction and expansion traffic organization plan. By using the fuzzy analytic hierarchy process to determine the weight of the traffic organization plan evaluation indicators, calculate the degree of membership and build an evaluation model, combined with the G4 highway reconstruction and expansion case, we evaluate different traffic organization plans and determine the best plan for final use. Finally, the traffic organization plan was simulated through TransCAD software, and the V/C ratio of the road network was found to be within an acceptable range.
