1 Andre Tok, Miyuan Zhao, Joseph Y.J. Chow, Stephen G. Ritchie, and Dimitri Arkhipov, University of California at Irvine 2010 Innovations in Freight-Demand Modeling and Data Symposium

2  Multiple freight data sources  Different user-interface designs and architecture  Availability of data definitions  Data dictionaries not always explicitly provided  Inconsistent data formats  Creates potential incompatibilities for modeling and analysis  Text-based data  Inability to assess scope and relevance of datasets

3  User-centered online tool  Convenient access through web-based architecture (http://moon.its.uci.edu/calfred/)  Standardized interface, centralized location for obtaining freight data from a variety of public sources  Data definitions  Downloadable data dictionaries and lookups associated with each data source  Data formats  Data tables associated with each data source can be downloaded in a variety of formats (tab-delimited, csv, html) to accommodate user needs  Data evaluation and assessment  Time-series and spatial analysis tools provide convenient evaluation and visual assessment of data
