For years, urban development in Southeast Asian cities like Bangkok in Thailand and Metro Manila in the Philippines has resulted in serious traffic problems. To cope with this situation, the formal Traffic impact assessment (TIA) was recently started. This paper aims to explain the current TIA applications in these two cities and compare their strengths and weaknesses. Moreover, obstacles are discussed together with possible remedies. We have classified the obstacles into four issues, namely institutionalization and legislation, unavailability of standard process, lack of knowledge, and budget limitation. Pragmatic examples are elucidated to provide clear perceptions. The study proposes two strategic points, concerned players and implementation stages. Five players, including governments, developers, consultants, academic persons, and community, should be encouraged to fulfill significant roles in three stages: promotion for the necessity, formulation, and evaluation processes. Ultimately, it is expected to be a case study to learn how to effectively set up TIA.
