基于不同收费模式的高速公路收费站货车碳排放模型

Truck Carbon Emission Model of Expressway Toll Station Based on Different Toll Modes

为顺应全球“节能减碳”趋势,助力实现“碳达峰、碳中和”目标,本文在排队论、车流波动理论分析的基础上,提出了不同收费模式下的高速公路收费站货车碳排放量化方法。该方法根据国内外相关研究和理论分析,针对货车通行ETC技术的应用,依据收费模式的不同,建立了货车碳排放计量模型,并通过河南省高速公路收费站现场调研和收费数据进行模型因素分析和参数标定。最后以郑州东三环南收费站为例计算货车在不同收费模式下的碳排放量,结果显示,ETC收费模式下货车进出收费站时,各阶段碳排放量成线性关系;MTC收费模式下货车进出收费站时,在加速阶段碳排放量显著增大;与MTC收费模式的碳排放相比,货车在ETC收费模式下进出收费站的碳排放量将减少约2.5倍,验证了货车ETC系统的应用对于收费站节能减碳的显著效果,可以为收费站改扩建和运营管理提供定性和定量的参考。

In order to comply with the global trend of"energy conservation and carbon reduction"and help achieve the goal of"carbon peaking and carbon neutralization",this paper proposes a quantitative method for carbon emissions of trucks at expressway toll stations under different toll modes based on the theoretical analysis of queuing theory and traffic flow fluctuation.According to the relevant research and theoretical analysis at home and abroad,aiming at the application of ETC technology for truck traffic,and according to the different charging modes,this method establishes a truck carbon emission measurement model,and carries out model factor analysis and parameter calibration through the field survey and charging data of highway toll stations in Henan Province.At last,taking Zhengzhou East Third Ring South Toll Station as an example,the carbon emissions of freight cars under different charging modes are calculated.The results show that the carbon emissions of each stage are linear when freight cars enter and exit the toll station under ETC charging mode;Under MTC charging mode,when trucks enter and exit the toll station,the carbon emissions in the acceleration phase increase significantly;Compared with the carbon emissions of MTC charging mode,the carbon emissions of trucks entering and leaving the toll station under ETC charging mode will be reduced by 2.5 times,which verifies the remarkable effect of the application of truck ETC system on the energy conservation and carbon reduction of toll stations,and can provide qualitative and quantitative reference for the reconstruction and expansion of toll stations and operation management.
