Abstract

Shipping emission inventory is the basis of regional air pollution assessments and pollution prevention and control policies. The accuracy depends to a large extent on the calculation results of every single ship based on AIS. This paper establishes a regional stratified sampling emission model based on the emission calculation of every single ship to improve the efficiency and precision of regional shipping emission inventory preparation. It performs calculations according to waterway characteristics, ship types and main engine power. The key findings of this paper include (1) the fast algorithm calculates exhaust emissions using complete ship information, helping reduce the uncertainty caused by the absence of single ship parameters during estimation, (2) when the ship sampling ratio is not lower than 1/3, the relative error of emission results is less than 3% and (3) the preparation of shipping emission inventory using the fast algorithm significantly improves the calculation efficiency and accuracy.

利用 AIS 数据编制航运排放清单：分层随机抽样法

航运排放清单是区域空气污染评估和污染防治政策的基础。其准确性很大程度上取决于基于 AIS 的单船计算结果。本文建立了基于单船排放计算的区域分层抽样排放模型，以提高区域航运排放清单编制的效率和精度。该模型根据航道特征、船舶类型和主机功率进行计算。本文的主要结论包括：（1）快速算法利用完整的船舶信息计算废气排放，有助于降低估算过程中由于单船参数缺失而导致的不确定性；（2）当船舶抽样比例不低于 1/3 时，排放结果的相对误差小于 3%；（3）利用快速算法编制航运排放清单可显著提高计算效率和精度。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
