The transportation industry plays a significant role in greenhouse gas emissions and global temperature rise. Sustainable transportation development can improve social welfare and economic conditions while preserving the environment and reducing carbon emissions. This dissertation examines various strategies for sustainable transportation development, including restricting the purchase and use of fossil-fuel vehicles, promoting the adoption of electric vehicles, and expanding public transportation. In this regard, the effectiveness of different monetary and non-monetary government policies on sustainable development goals and the profitability of various automotive industry agents has been investigated and eva‎luated.In the first problem, the government's supportive and tax policies for the development of sustainable transportation, with the presence of fossil fuel vehicle manufacturers, electric vehicle manufacturers, and electric vehicle battery manufacturers as an influential factor in promoting electric vehicles, were studied. In this problem, the amount of subsidy for the purchase of electric vehicles and the amount of subsidy to the battery manufacturer for research and development and reducing battery prices have been considered, and the amount of tax levied on fossil fuel vehicle buyers and fossil fuel to limit the purchase and use of fossil fuel vehicles and the tendency to buy electric vehicles have been examined under different scenarios. In the second problem, in order to develop sustainable transportation, various monetary policies, including tax, subsidy, and public transportation (bus) development policies, as well as non-monetary policies, including allowing electric vehicles to access bus lanes, have been considered for the government. In this circumstance, two fossil fuel and electric vehicle manufacturers compete with each other and determine the prices of their products. In these problems, the government has taken into account various economic, social, and environmental objectives for the development of sustainable transportation and has made its decisions based on the priority of each of these objectives in different conditions and the decisions of other production factors. The problems have been solved using game theory and using real data from Norway. The various management points extracted from the results are as follows. In order to attract more electric vehicle customers and increase the profits of electric vehicle manufacturers and battery manufacturers, the driving range of electric vehicles with a single charge should be increased, and the government should provide a lot of facilities to electric vehicle customers. If the government's priority is environmental objectives and the promotion of electric vehicles, it should levy a significant tax on fossil fuels and fossil fuel vehicles; however, the government does not generate a lot of revenue by imposing a high tax on vehicles and fossil fuels, and to maximize revenue, it should reduce the fuel tax while maintaining a high tax on vehicles, so that it does not face low demand for fossil fuel vehicles. Also, if the government prioritizes social welfare, it should refrain from imposing a high tax.
