Changes in traffic carbon emissions with traffic conditions and their corresponding control strategies

Abstract

Road traffic carbon emissions have a significant impact on the atmospheric environment, and changes in traffic conditions can affect road traffic carbon emissions, while changes in traffic state and traffic infarction can reflect traffic conditions, in addition, there are differences in carbon emissions generated by different fuel vehicles. Therefore, this paper sequentially determines quantitative indicators of traffic states and traffic infarction as well as macro control strategies to improve traffic carbon emissions. Furthermore, taking the confluence area as the analysis object, the impact of traffic state and traffic infarction on carbon emissions is sequentially analysed with actual traffic flow data and statistical methods, and corresponding models are constructed, meanwhile, based on the analysis results, mainline speed limit control strategies based on traffic state and traffic infarction, as well as the control strategy based on the combination of multi-fuel vehicles, are presented. The analysis results show that changes in both traffic states and traffic infarction can affect traffic carbon emissions from mainline and on-ramp, which can affect traffic conditions essentially. Moreover, the total carbon emissions under the combination of gasoline minibuses and diesel minibuses decrease with the increase in the ratio of gasoline minibuses.
