Research on Quantitative Methods for Vehicle Carbon Emissions during Expressway Operation Period
The online toll collection data of expressway has the characteristics of complete monitoring equipment,high statistical data accuracy,and full sample size.Based on the online toll collection data of expressway and the fusion of vehicle fuel type data,taking into account factors such as traffic volume of different vehicle models and benchmark energy consumption values of different vehicle models,a calculation method for expressway carbon emissions based on road network granularity is constructed.Taking Guangdong Province as an example,from the perspective of total distribution,the sections with high carbon emissions mainly appear in the Pearl River Delta region and the provincial passages with a high proportion of trucks;from the perspective of carbon emission intensity per kilometer,the sections with higher carbon emission intensity are mainly located in the Pearl River Delta and Lechang-Guangzhou Expressway.
