In order to compute the network scale of urban rail transit, the paper proposed a mutualist model describing the network scale, through investigating the main influencing factor of network scale-the population and the relationship between population and network. The equilibrium point of different equations was given practical meaning.calibrating the key physical quantities, the nonlinear differential equations have been solved by using Runge–Kutta. Applying the model to predict the population and network scale in main city in Hefei in 2020 and long future, compared with the traditional travel demand model and network service coverage model. The result are basically accordant, so the new model is feasible.The theory model provides a new means of quantitative analysis method for urban rail transit network planning, So it has important theoretical and practical significance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
