CubeView: a system for traffic data visualization

Due to the huge amounts of data being stored in traffic and transportation databases as well as many other information repositories, traffic data visualization is receiving substantial interest from both academia and industry. The Minneapolis-St. Paul (Twin-Cities) traffic archival stores sensor network measurements collected from the freeway system in the Twin-Cities metropolitan area. In this paper, we present a web-based visualization package for observing rapid summarization of major trends. In the underlying database, we modeled the traffic data as a multi-dimensional data warehouse to facilitate the on-line query processing used in the visualization software. We also discuss some research issues in mining traffic and transportation data.
