Comprehensive Analysis of Traffic Operation for On-Street Parking Based on the Urban Road Network

With the continuous improvement of the world's economic development level, traffic pressure on the road networks of major cities around the globe has been increasing. Influenced by multiple factors, traffic pressure on urban road networks is not balanced in different directions and at different times. We evaluated and analyzed the efficiency of traffic operations and pollutant emission levels at different time periods and traffic volumes using micro traffic simulation software against the background of real roads in the Nishi-Waseda area of Tokyo. We determined the standard traffic volume based on the pollutant emission level and designed three on-street parking schemes, considering different driving habits and application scenarios, and conducted a comparative analysis of different parking scenarios. In terms of pollutant emission levels, scheme A (far to near scheme) reduced carbon monoxide emissions by 2.86% and 0.97%, respectively, compared to the other two parking schemes. The NOx and VOC emissions were also lower than those in the other two scenarios. This study aims to develop a methodology for assessing traffic operations and pollution emissions based on a real road environment. By designing and comparing different on-street parking schemes, a comparative analysis revealed the efficacy of various parking management strategies in mitigating the environmental impacts. Moreover, this study provides a valuable reference for understanding dynamic changes in traffic pressure on urban road networks and their impact on the environment.
