2020年山东省实施了高速公路收费政策的调整,对干线公路网货车的交通流量和碳排放格局产生了显著影响。本文基于收费政策调整前后的数据,分析了不同类型货车(小型货车、中型货车、大型货车、特大型货车与集装箱车)碳排放的变化情况,探...2020年山东省实施了高速公路收费政策的调整,对干线公路网货车的交通流量和碳排放格局产生了显著影响。本文基于收费政策调整前后的数据,分析了不同类型货车(小型货车、中型货车、大型货车、特大型货车与集装箱车)碳排放的变化情况,探讨了山东省不同饱和度干线公路路段的不同平均车速的货车碳排放规律。借助交调站各货车车型交通流量数据,基于IPCC改进的碳排放计算模型,本文计算并对比了政策调整前后的碳排放差异。研究表明,收费政策调整对货车特别是重型货车的碳排放分布产生了重要影响。研究结果表明:① 收费政策调整对高速公路和普通国省道的货车通行路径选择与碳排放分布特征产生了显著影响,特别是在特大货车这一车型上的效果尤为明显。② 高速公路与普通国省道之间碳排放压力存在显著不均衡。以济青通道和鲁中通道为例,平行路段中普通国省道的碳排放压力明显高于高速公路,很有必要通过优化调整高速公路收费政策来平衡两类道路的碳排放负担,鼓励更多货车优先选择高速公路通行。本研究为收费政策优化、交通碳排放平衡、干线公路低碳发展及高速公路网经济效益提升提供了重要参考。In 2020, Shandong Province implemented adjustments to its highway toll policies, significantly impacting the traffic flow and carbon emissions distribution of freight trucks on the trunk highway network. This paper analyzes the changes in carbon emissions of various truck types (small trucks, medium trucks, large trucks, extra-large trucks, and container trucks) based on data before and after the toll policy adjustment. It explores the carbon emission patterns of trucks at different average speeds across trunk highway sections with varying saturation levels. Using traffic flow data from traffic monitoring stations for various truck models and an IPCC-modified carbon emission calculation model, this study calculates and compares the differences in carbon emissions before and after the policy adjustment. The results indicate that toll policy adjustments have significantly impacted the carbon emissions distribution of trucks, especially heavy trucks. Specifically: (1) Toll policy adjustments have had a notable impact on the route choice and carbon emission distribution characteristics of trucks on highways versus regular national and provincial roads, with particularly evident effects on extra-large trucks. (2) There is a significant imbalance in carbon emission pressures between highways and regular national and provincial roads. For example, on parallel routes such as the Jinan-Qingdao corridor and the central Shandong corridor, the carbon emission pressure on regular national and provincial roads is significantly higher than on highways. It is essential to optimize toll policies to balance the carbon emission burdens between these two types of roads, encouraging more trucks to prioritize highway routes. This study provides valuable references for toll policy optimization, traffic carbon emission balancing, low-carbon development of trunk highways, and the enhancement of economic benefits in the highway network.展开更多
