Impact of the built environment on the vehicle emission effects of road pricing policies: A simulation case study

In order to develop a road pricing policy that is effective in reducing vehicle emissions, this paper explores the relationship between road pricing, the urban built environment, and vehicle emissions. Existing studies generally tend to choose a city or an entire region as the research object. For this reason, these kinds of studies can neither analyze the differences in the vehicle emission effects of road charging on regions with different built environment attributes, nor distinguish how different built environment attributes affect the vehicle emission effects of road user charging. To fill in the research gap, this paper focuses on the influences of road charging on the vehicle emissions of regions with different built environment characteristics. In order to achieve the above mentioned goal, this paper first applies a method which combines the land use and transport interaction model with a vehicle emission model to simulate the automobile emissions under different road pricing schemes. Then, using multiple regression analysis, this paper establishes the association between the built environment attributes and the vehicle emissions under different road charging levels. Additionally, using factor analysis and cluster analysis, this research further distinguishes the vehicle emission effects of road pricing based on attributes of the built environment. The results confirmed that road pricing affects vehicle emissions in different regions differently. More importantly, not every region will experience decreases in vehicle emissions after the implementation of a road charging policy. The presence of retail amenities, good street design, and public transportation, the more significant the effect of road pricing in reducing vehicle emissions. Furthermore, a healthy jobs-housing balance is also conducive to the decline of regional automobile emissions as well.
