Tehran, as a major metropolitan city, faces significant challenges in urban governance—particularly in the field of transportation management—such as excessive centralization, lack of transparency, and limited citizen participation. This study aims to design policy measures that strengthen technologically enabled participatory governance by leveraging the potential of emerging urban technologies, including intelligent traffic systems, the Internet of Things (IoT), and open data platforms. The research employs a descriptive–analytical and qualitative approach, utilizing policy analysis and thematic analysis frameworks to examine the current situation, identify institutional and technological barriers, and formulate alternative policy options. Findings reveal that the inefficiency of current governance mechanisms stems from weaknesses in open-data infrastructure, a control-oriented perception of technology, institutional fragmentation, and the absence of technology-based accountability systems. To address these challenges, four key policy actions are proposed:

(1) developing a comprehensive open data framework;

(2) designing a digital participation platform;

(3) fostering technological collaboration with civil society organizations; and

(4) establishing a transparent, technology-driven accountability system.

Based on a multi-criteria evaluation, these policies are found to be feasible, socially effective, and institutionally acceptable. The study concludes that transitioning toward technologically participatory governance in Tehran requires institutional reforms, enhancement of public digital literacy, and a paradigm shift from technology for control to technology for engagement.
