Since its inception in 1978, the National Transit Database (NTD) has become the sole source of standardized and comprehensive data for use by all constituencies of the U.S. transit industry. However, accessing multiple years of NTD data was an especially tedious process. One reason is because NTD data were and continue to be collected and distributed by the Federal Transit Administration (FTA) annually on separate files.
To perform a trend analysis, for example, one must first learn about the file structures that may vary from year to year, identify the specific variables of interest from the vast number of potential NTD variables, and then extract the data from specific files for specific transit systems. The urban version of the Integrated National Transit Database (Urban iNTD) system has been developed by the Florida Department of Transportation (FDOT) Transit Office to facilitate the process. Integrating NTD data that date back to 1984, the system provides a set of user-friendly tools to enable the quick application of these data for trend analyses, peer comparisons, and other general data inquiries.
- Quick access to multiple years of Urban NTD data (since 1984).
- Quick access to calculated transit performance measures.
- Quick access to aggregate data at the agency-wide and state level.
- Automated peer selection process based on the TCRP G-11 methodology.
- Easy identification and selection of variables.
- Display of data on tables, forms, charts, and reports.
- Quick adjustment of financial variables to account for inflation.
