    • Abstract:
      In this project, University of Florida researchers

      collected field data along several highways to

      evaluate travel time measurements from several

      sources: STEWARD, BlueTOAD, INRIX, and HERE.

      STEWARD (Statewide Transportation Engineering

      Warehouse for Archived Regional Data) is a central

      repository maintained by the Florida Department

      of Transportation (FDOT), which collects data from

      FDOT Traffic Management Centers. STEWARD’s flow

      and speed data can provide travel times based on

      spot measurements. BlueTOAD (Bluetooth Travel-time Origination and Destination) is technology

      that detects anonymous Bluetooth signals from

      passing vehicles; detection of the same signal by

      two widely spaced BlueTOAD units can be used

      to obtain travel times. INRIX is a company that

      collects traffic information worldwide as the

      basis for a number of applications related to road

      travel; INRIX can provide real-time or archived

      travel time data. HERE, formerly NAVTEQ, is a

      product of the communications company Nokia;

      HERE brings together a number of mapping

      services, including data collection services. HERE

      data include real-time data from GPS, smart

      phones, and consumer and commercial sources,

      using proprietary methods to derive information,

      including travel times.
