The current trend of the global increase in energy consumption has presented societies with several major crises including environmental pollution and the acceleration of diminishing energy supplies. Energy storage and pollutant reduction in the city play a crucial role in the process of conserving the existing energy. In addition, the transportation sector should be emphasized due to its importance. Further, it can bring significant amounts of annual economic savings to the people and governments by reducing the energy consumption and adverse environmental effects, as well as reducing the travel time and unwanted delays. Therefore, the present study aimed to determine the most important parameters of environmental pollutant emissions in the urban transport sector and develop the system dynamics model of Tehran urban transport. To this aim, six scenarios including Business As Usual, Priority to the Development of Public Transport, Technical Progress, Administrative Rules and Regulations Management (ARM), Travel Demand Management (TDM), and Comprehensive Policy (CP) were quantitatively analyzed. Based on the results, both TDM and ARM scenarios were effective in the short term. Although CO₂ emissions in the TDM scenario were estimated at about 155,072 million kilograms in 2015, which was better than all individual policies, the reduction of the ARM scenario was better after 2019 and the CO₂ emissions of the ARM scenario were estimated to be 153,940 million kilograms in 2025. However, the CP scenario had generally the best performance compared with all the individual policies. Finally, by implementing the scenarios simultaneously, we observed that each plays a role in improving the situation while reducing energy consumption and CO₂ emissions significantly. In particular, CO₂ emissions in the CP scenario were estimated to be 125,934 million kilograms by 2025.

当前全球能源消耗的增长趋势已给社会带来了数个重大危机，包括环境污染和加速的能源供应减少。城市的储能和减少污染物在节约现有能源的过程中起着至关重要的作用。此外，由于其重要性，应强调运输部门。此外，通过减少能源消耗和不利的环境影响，以及减少旅行时间和不必要的延误，它可以为人民和政府带来大量的年度经济节省。因此，本研究旨在确定城市交通部门环境污染物排放的最重要参数，并开发德黑兰城市交通系统动力学模型。为此，定量分析了“日常照常”，“公共交通发展的优先级”，“技术进步”，“行政规章管理”（ARM），“旅行需求管理”（TDM）和“综合政策”（CP）等六个方案。根据结果​​，TDM和ARM方案在短期内均有效。虽然一氧化碳2015年，TDM情景中的₂排放量估计约为155,072百万千克，优于所有单个政策，ARM情景的减少量在2019年之后更好，ARM情景中的CO ₂排放量估计为1539.4亿公斤到2025年，CP方案与所有单个策略相比通常具有最佳性能。最后，通过同时实施这些方案，我们发现每种方案在改善情况的同时，还可以显着减少能耗和CO ₂排放。特别是，到2025年，在CP情景中，CO ₂排放量估计为125,934百万千克。
