摘要:AbstractThe main problems of traffic at present are low design and over design, and this paper puts forward equilibrium theory of road capacity based on the main problems and then puts forward corresponding model based on equilibrium theory for the purpose of guiding and improving the design of road, The paper takes Zhouzhuang Road in Wuhan as example, and conducts capacity equilibrium test based on different traffic organization optimization scheme. Meanwhile, the paper will evaluate the model with VISSIN, and then demonstrates the feasibility and effectiveness of capacity equilibrium model.
