But there is a great dissimilarity between the real traffic system and this hypothesis. In this paper the authors considered the above dissimilarity and adopted a logit model to describe the drivers’ route choice behavior under real-time traffic state information. When modeling, each driver’s characteristics are taken into account. These characteristics include gender, age, income, familiarity with the road network, trip purpose and so on. Finally, by analyzing SP and RP survey data in the Shanghai urban expressway A20, the authors proved the validity and rationality of the established logit model.
