چکیده    Increasing pressures caused by negative consequences of transportation and traffic problems inmajor cities, have resulted many attempts towards improvement of planning and managementof transportation systems, according to sustainability objectives. in this paper, a comprehensivemodel is developed using a system dynamics approach to evaluate sustainable urban transportation.this model includes social, economical, environmental, and urban transportation variables.then, the validation of the model according to actual data for years 1994 to 2009 of city of mashhadare performed. the base year for simulation was 2009 and the horizon year was 2044. thisstage is very important because all of the analyses and decisions made in the following steps willbe based on the calibrated model. the sensitivity analysis of the parameters of the model showedthat the selected variables have considerable influences on urban transportation sustainability. theproposed model can be used to find the optimal strategy for sustainable urban transportation.
