One of the methods of controlling traffic in central and high traffic areas of major cities is creating central congestion charging zone and the ban on entry private car into this zone at certain hours of the day. This interdictions and control infrastructure constraints cause significant problems for residents and who has been working in the central zone of the cities. This interdictions and traffic constraints cause many urban systems and regional and local problems in Tehran, because of importance of those changes this study is to evaluate and assess the influence of central Tehran congestion charging zone on the mode choice of people trips for entry into the zone. In this context, the questionnaires were collected from the central zone of Tehran and for modeling of mode choice in this study, due to the discrete nature of data, multinomial logit model was used and the implementation of this model was done using the TransCAD software. The results showed that business dependence on the automobile, the number of passengers in the car, having an entry permit to the congestion zone and the amount of commute to the congestion zone are including influencing parameters on the use of private cars in order to enter the study area. Model evaluation showed estimated mode matches with people selected mode at 84%.
