摘要:

在“双碳”政策背景下,维护生态平衡,减少碳排放势在必行。现如今,准确测算大范围路网车辆碳排放指标十分关键。为此,本研究提出了一种基于多源数据融合的高速公路网车辆碳排放测算方法。首先提出面向碳排放统计的基础数据清洗方法,对后续碳排放测算所需基础数据进行清洗。其次建立高速公路碳排放测算模型,进而设计相关的计算流程。最后以广东省高速公路网为例,测算了2020年9月至2021年6月的车辆碳排放量,并与中国碳核算数据库进行对比、验证所提出方法的科学性与可靠性。研究表明:虽然微型小型客车车均碳排放量较小,但总碳排放量在各车型中占比最大,达到52.1%;汽油车碳排放总量占比达到了49.8%,高于柴油车的45.4%和其它类型能源车的4.8%,大力推广新能源汽车能有效地降低高速公路碳排放量;此外,研究发现“新冠疫情”下不同车辆的出行规律存在明显的差异,但对交通运输经济的整体影响有限。

Abstract:

Under the background of dual-carbon policy, it is imperative to maintain ecological balance and reduce carbon emissions. Nowadays, it is very important to accurately measure the carbon emission index of vehicles on a wide range of road networks. Therefore, this study proposed a measuring method of vehicle carbon emission in expressway network based on multi-source data fusion. Firstly, a basic data cleaning method for carbon emission statistics was proposed to clean the basic data required for subsequent carbon emission calculation. Secondly, the highway carbon emission calculation model was established, and then the related calculation process was designed. Finally, taking the whole highway network of Guangdong province as an example, this paper calculated the vehicle carbon emission from September 2020 to June 2021, and compared the calculation results with China’s carbon accounting database.Through this method, the proposed method was proved to be scientific and reliable. The research shows that the average carbon emission of mini buses in Guangdong province is small, but the total carbon emission accounts for the largest proportion of all types of vehicles, up to 52.1%; the total carbon emission of gasoline vehicles accounts for 49.8%, which is higher than that of diesel vehicles (45.4%) and of other energy vehicles (4.8%). Vigorously promoting new energy vehicles can effectively reduce the carbon emission of expressways. In addition, the study finds that there are significant differences in the travel patterns of different vehicles under COVID-19, but the overall impact on the transportation economy is limited.
