Summary        In recent years, the problem of traffic air pollution in urban areas has attracted people’s attention. The use of traffic management strategies to guide private vehicle users to transfer to public transportation or low emission vehicles is the key to reducing traffic air pollution in urban areas.
       This study continues the research results of the previous two years and analyzes respondents from different regions and different socioeconomic conditions. It is found that women, older people, and people with higher education pay more attention to the impact of traffic air pollution on health, and their willingness to use public transportation is also higher. However, there is no significant difference in the willingness of people with different income levels. In different regions, respondents from Taipei, New Taipei, and Kaohsiung are all more concerned about traffic and air pollution and are willing to move vehicles than respondents from Taichung.
       In terms of the feasibility and public acceptance of each strategy, it can be divided into three major aspects: private transportation management, public transportation enhancement, and low emission vehicles promotion. Each strategy differs from region to region, and respondents may be willing to transfer transportation, with significant differences. Through scenario setting, the air pollution reduction benefits after the promotion of management strategies are estimated. Taking PM2.5 as an example, Taipei and New Taipei can reduce emissions by approximately 0.4%–1.8% under the promotion of various management strategies. In Taichung, the decrease is 0.2%–1.6%, and Kaohsiung is approximately 0.5%–3.9% decreased.
       This plan refers to the analysis results of the previous questionnaire, the effectiveness and feasibility of strategy implementation, and relevant domestic and foreign actions, to develop short-, medium-, and long-term pollution reduction strategy recommendations. The short-term (1–2 years) strategy includes optimizing public transportation routes, strengthening transferring connections, managing parking rates, and providing electric vehicle purchase subsidies. Mid-term (3–4 years) strategies include reducing free parking spaces for schools and enterprises, reducing roadside parking spaces, expanding air quality maintenance areas, etc. Long-term (more than 5 years) recommendations are related to the national long-term policy planning and require public opinion communication, feasibility investigation and research, etc., including the implementation of promoting low-carbon transportation zones and increasing the cost of high-polluting vehicles.
