Sustainable development has become a major concern for policy makers and planners in the world today. Sustainable development is composed of three main aspects: environmental, economical and social. transportation has significant economical, social and environmental impacts, and is an important factor in sustainability. urban transportation system is a complex system with multiple variables and nonlinear feedback loops. Transportation can not be rated as an independent criteria.This article aims to present a dynamic model for urban transportation system concerning sustainable urban transportation in a way that by using this model the complicated and dynamic nature of urban transportation system will be understood and the impact of policies will be analyzed. So the best has been done in the article using systems dynamic approach, a completed and integrated Model for Tehran transportation system be introduced considering sustainable urban transportation system concept and the system dynamic conduct be analyzed. In continue some policies have been introduced by model simulating in order to increase urban transportation system utility and urban traffic parameters improvement. This model has been analyzed in vensim software using the data from Tehran. Results show that compound performance of presented policies has a great impact on urban transportation systems and Tehran traffic parameters improvement.
