Exhaust emission analysis of expressway toll station based on PEMS data

Abstract

The complex operation characteristics of vehicles at tollbooths on expressway lead to the increase of vehicle emission intensity. In order to reduce energy emissions at toll stations on highways, the toll stations on highways have been replaced with ETC charging mode. In order to effectively evaluate the environmental and energy efficiency after the abolition of toll stations, it is necessary to analyze the correlation between ETC charging mode and lane emission under manual charging mode. Using PEMS data, this paper analyzes in detail the correlation between vehicle operating characteristics and emissions in ETC lane and toll lane. The results show that ETC lane can increase the vehicle traffic efficiency and effectively reduce the exhaust emissions at the toll station. The results of this study will provide a basis for evaluating the energy efficiency of expressway tollbooths after their removal.
