Traffic Data Imputation
Traffic data imputation aims to reconstruct missing values in traffic datasets, crucial for reliable analysis and application in intelligent transportation systems. Current research heavily focuses on leveraging spatiotemporal correlations within the data using advanced techniques like tensor decomposition, graph neural networks, and recurrent neural networks, often incorporating semantic information about the road network. These improved imputation methods enhance the accuracy and efficiency of downstream applications, such as traffic prediction and optimization, by providing more complete and reliable data for analysis. The development of robust and scalable imputation techniques is vital for maximizing the utility of increasingly large and complex traffic datasets.
