【 摘 要 】

In this paper, the comparison of transportation CO2 characteristics and vehicle emission structure of two typical urban roads in Beijing are studied from the urban road scale. We found that traffic CO2 emissions from the North Fifth Ring Expressway is much higher than the Datun and Beichen West urban main road. In both of the two typical urban roads, private vehicles such as ordinary passenger cars and SUV constitute the main part of transport CO2 emissions. The percentage of CO2 emitted by trucks in the North Fifth Ring is higher than that in the main urban area while the percentage of CO2 emitted by public transport is lower than that in the main urban area. Based on this, some recommendations on transportation carbon emission reduction is proposed in this paper.
