Impacts of Environmental Concern on the Approval of Low-carbon Traffic Policy

The government should formulate transportation policies to encourage low-carbon travel, thereby reducing automobile exhaust pollution. Designing effective policy requires a thorough understanding of the psychological factors that influence low-carbon travel. The structural equation model(SEM)is used to study the impacts of environmental concern on the approval of the low-carbon transportation policy. Based on the basic principles of SEM, a model hypothesis is established, and the data is analyzed by Mplus. The results show that environmental attitudes directly influence environmental behaviors and public transportation preference. Meanwhile, environmental behaviors directly affect public transportation preference, and public transportation preference directly influences the approval of the low-carbon traffic policy. However, environmental attitudes and behaviors do not directly influence the approval of the low-carbon transportation policy. At the 95% confidence level, gender, marital status, private car ownership, house ownership, and whether or not drive to work have no significant effect on the SEM. However, at the 90% confidence level, gender and education level have significant effects on SEM.
