Abstract: Logit model is among the most important model in SUE DTA study. A lot of work have been done based on Logit model. As the other very important SUE DTA model, Probit model has not been the focus of many researcher. This paper presents a SUE model based on Probit model, which aims at building up the Probit model with constant demand. The existence and uniqueness of the model is presented, Finally, a algorithm is given.

Abstract: DTA modeling is first presented by Daganzo and Sheffi aiming at building up model to descript the traffic assignment in terms of practical application., their work lays the foundation of SUE (Stochastic User Equilibrium) modeling. This paper makes a brief review of Probit model, a integrated model based on Probit model with elastic traffic demand is presented by using SUE method, the existence and uniqueness of the solution to the model is dicussed, the solution to the model is presented. Finally, a case study is presented.
