This paper is composed of two parts by its main contents. In the first part of the paper, a transit network representation and some useful concepts are introduced. Also, an actual link cost function of transit network is defined. Then, a minimization problem is formulated which yields a Stochastic User Equilibrium (SUE) assignment with elastic transit demand and bottlenecks model for public transport network. In the second part of the paper, the solution algorithm for the model given in the first is proposed. Numerical examples are used to illustrate the applications of the SUE transit assignment model.
