Abstract

The European Civil Aviation Conference (ECAC) noise estimation model is widely used for its simplicity and efficiency. However, its reliance on fixed thrust coefficients for thrust calculation limits the accuracy of noise estimation. This study presents an innovative Copula-ECAC model for estimating aviation noise around airports to address this limitation. The core of the proposed model lies in leveraging the Copula theory to construct joint distribution models of thrust coefficients for various aircraft types. By utilizing the robust capability of Copula functions to characterize dependency relationships, the model effectively captures and simulates the complex dynamic interactions between different thrust coefficients. Applied to Nanjing Lukou International Airport in China, the Copula-ECAC model demonstrates superior performance compared to mainstream ECAC models in terms of prediction accuracy and generalization ability. With a coefficient of determination consistently exceeding 0.90, the model’s reliability and practical value are fully validated.

机场周围航空噪声估计的Copula-ECAC模型

欧洲民航会议（ECAC）噪声估计模型以其简单、高效的特点得到了广泛的应用。然而，推力计算依赖于固定的推力系数限制了噪声估计的准确性。本研究提出了一个创新的Copula-ECAC模型来估计机场周围的航空噪声，以解决这一限制。该模型的核心是利用Copula理论构建不同机型推力系数的联合分布模型。该模型利用Copula函数表征依赖关系的鲁棒性，有效地捕捉和模拟了不同推力系数之间复杂的动态相互作用。将Copula-ECAC模型应用于中国南京禄口国际机场，在预测精度和泛化能力方面均优于主流ECAC模型。模型的决定系数始终大于0.90，充分验证了模型的可靠性和实用价值。

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.
