Knowledge discovery from transportation network data Wei Jiang, Jaideep Vaidya, Zahir Balaporia, Chris Clifton, and Brett Banich   View Paper (PDF)   Return to Industrial Session 5: New Applications for Databases Abstract Transportation and logistics are a major sector of the economy, however data analysis in this domain has remained largely in the province of optimization. The potential of data mining and knowledge discovery techniques is largely untapped. Transportation networks are naturally represented as graphs. This paper explores the problems in mining of transportation network graphs: we hope to find how current techniques both succeed and fail on this problem, and from the failures, we hope to present new challenges for data mining. Experimental results from applying both existing graph mining and conventional data mining techniques to real transportation network data are provided, including new approaches to making these techniques applicable to the problems. Reasons why these techniques are not appropriate are discussed. We also suggest several challenging problems to precipitate research and galvanize future work in this area. ©2006 Association for Computing Machinery
