Abstract :

This research examines the impact of energy consumption reduction policies, carbon dioxide (CO₂) emission reduction and economic growth in urban transportation systems. Given the increasing importance of environmental issues and sustainable development, system dynamics modeling and simulation have been chosen as the primary approach for this study. The research has been conducted in the context of Tehran, and efforts have been made to simulate the relationship between energy consumption, CO₂ emissions, and economic growth using the Vensim software. Initially, key variables and subsystems related to transportation, CO₂ emissions, and economic growth were identified, and the relationships among them were modeled. Various scenarios, such as increasing fuel prices and developing subway and bus rapid transit lines, were examined. The results showed that the development of public transportation infrastructure could have a significant impact on reducing CO₂ emissions. Additionally, rising fuel prices have negative short-term effects on household income but lead to decreased traffic and air pollution in the long term. This research emphasizes that investing in renewable energy and developing sustainable transportation plays a crucial role in reducing environmental impacts and improving quality of life. This study can assist urban policymakers in making more effective decisions for enhancing urban transportation and mitigating environmental effects, utilizing scientific approaches and dynamic system modeling.
