An Overview of Transportation Data
Introduction
Transportation data is the foundation for informed policy decision making. Transportation data is
collected and managed as an asset. These data provide insight into many different aspects of the
transportation system, including:
" Transportation system assets and their physical condition.
" Safety, system operation, and performance.
" Travel behavior, demography, and modal data.
" Transportation economics, finance, and programming.
" Freight movement, volumes, and modes.
" Project planning and development.
" Public opinion data (to reflect attitudes and awareness).
For example, transportation system asset inventories and conditions of buses and bridges are
collected and reported to the Federal Transit Administration (FTA) National Transit Database
(NTD) and to the Federal Highway Administration (FHWA) National Bridge Inventory (NBI).
State DOTs use their own systems to collect and report their data to relevant federal agencies. In
Texas, these include the Texas Department of Transportation's (TxDOT's) PTN 128 (the transit
database) and TxDOT's Bridge Inventory, Inspection and Appraisal Program (BRINSAP).
Historically, these databases have been collected, stored, and managed as separate systems. As
geographic information systems (GIS) have evolved, many of the data sets have been available
in internet-based GIS. TxDOT maintains the website http://gis-txdot.opendata.arcgis.com-/ that
contains a broad range of data sets (See Figure 1).
