  7. Abstract:
  8. The transportation sector plays a critical role in three key dimensions: economy, environment, and energy, necessitating integrated planning approaches. This study introduces an innovative approach to simultaneously addressing economic, environmental, and energy aspects by optimizing urban transportation systems. The focus is particularly on passenger cars, which significantly contribute to environmental pollutants such as particulate matter (PM) and energy consumption. The innovation of this research lies in developing an integrated model using linear optimization methods. This model identifies the optimal mix of fuel portfolios and transportation technologies from an economic perspective, while incorporating environmental and energy constraints. The technologies examined include dual-fuel, electric, and low- and high-cost gasoline vehicles. Various scenarios, such as reducing PM emissions and mitigating greenhouse gas emissions, are analyzed. The results indicate that, to achieve an annual reduction in PM emissions, the share of electric vehicles must increase to 8.4%, while the share of low-cost gasoline vehicles must decrease from 95% to 88%. These changes result in a 15% rise in fuel consumption. The findings provide an economically optimal solution that simultaneously respects energy consumption and environmental emission constraints
