摘要:

交通数据插补是智能交通系统中的关键预处理步骤,支撑着下游交通服务的可靠性。尽管插补模型已取得显著进展,但由于三个关键缺口,实际应用中的模型选择与开发仍具挑战性:1)缺乏用于交通数据插补的模型分类体系,以追踪技术发展并突出其不同特征;2)缺乏统一的基准测试流程,难以在标准化交通数据集上进行公平且可复现的模型评估;3)缺乏在有效性、计算效率和鲁棒性等多个维度上联合比较模型的深入分析。为此,本文提出面向实践的交通数据缺失模式与插补模型分类体系,系统编目真实世界交通数据丢失场景,并分析现有模型的特征。我们进一步引入统一的基准测试流程,在不同缺失模式和缺失率下全面评估11个代表性模型,评估总体性能、挑战性场景下的性能和计算效率,并提供可视化。本工作旨在为交通数据插补提供整体视角,并作为智能交通系统中模型选择与应用的实践指南。

英文摘要:

Traffic data imputation is a critical preprocessing step in intelligent transportation systems, underpinning the reliability of downstream transportation services. Despite substantial progress in imputation models, model selection and development for practical applications remains challenging due to three key gaps: 1) the absence of a model taxonomy for traffic data imputation to trace the technological development and highlight their distinct features. 2) the lack of unified benchmarking pipeline for fair and reproducible model evaluation across standardized traffic datasets. 3) insufficient in-depth analysis that jointly compare models across multiple dimensions, including effectiveness, computational efficiency and robustness. To this end, this paper proposes practice-oriented taxonomies for traffic data missing patterns and imputation models, systematically cataloging real-world traffic data loss scenarios and analyzing the characteristics of existing models. We further introduce a unified benchmarking pipeline to comprehensively evaluate 11 representative models across various missing patterns and rates, assessing overall performance, performance under challenging scenarios, computational efficiency, and providing visualizations. This work aims to provide a holistic perspective on traffic data imputation and to serve as a practical guideline for model selection and application in intelligent transportation systems.
