【Abstract】 In this paper, the system character of urban transit network and the principle of passenger how to choose route when congestion exists is analyzed,also uncertain factors are discussed. Further, link cost function is developed and a stochastic user equilibrium assignment model which satisfies the SUE(Stochastic User Equilibrium) principle is formulated, then GA(Genetic Algorithm) is cooperated with the model. Finally, a simple numerical example is given.更多还原
