Dynamic Design of Green Products in Tehran's Public Transportation System (Challenges and Opportunities)

Air pollution and traffic in Tehran, as two major urban challenges, require effective solutions. Green public transportation, as one of the key tools in reducing negative environmental impacts, can play an effective role. This article examines the dynamic design of green products in Tehran's public transportation system. The aim of this study is to identify challenges such as lack of infrastructure, economic problems, and lack of public awareness, as well as opportunities such as the use of new technologies and government support. To achieve these goals, qualitative and quantitative methods have been used. Data have been collected through semi-structured interviews with experts and a survey of 200 Tehrani citizens. Preliminary results show that 55% of respondents are willing to use green transportation systems, while 80% emphasized the importance of appropriate infrastructure. The research hypotheses include the positive impact of green technologies on pollution reduction and the impact of government incentive policies on public acceptance. The main research question is: How can green technologies be used to improve the public transportation system in Tehran and reduce pollution?
