Statistical Methodology for Measuring and Improving Data Quality

Research Project

Data quality issues were being explored, along with paths to resolve them, for the Bureau of Transporation Studies' (BTS) Intermodal Transportation Database (ITDB). One principal recommendation is that BTS develop a software toolkit that would automate generic aspects of data quality assessments and systemize application of relevant domain knowledge. The ITDB integrates a number of diverse databases maintained by the U.S. Department of Transportation.
