• Description:
  This report provides an overview of travel surveys, including literature review and background, as well as the motivation for the
  
  research and development of the Global Positioning System Automated Travel Diary (GPS-ATD). The system requirements and
  
  specifications for the device development are presented and discussed. In addition, the detailed architecture, hardware, software,
  
  and user interface design are included. Vehicular and personal GPS-ATD systems were developed to support comprehensive
  
  traveler behavior studies. The GPS-ATD provides an intuitive user interface to capture trip activity information (trip purpose,
  
  travel mode, etc.), with minimal user input and burden during travel surveys. Each survey participant interacts with their own
  
  personal GPS-ATD, and information is automatically coordinated between personal and vehicular GPS-ATD units via ZigBee
  
  wireless. The system captures and logs data from the High-Sensitivity GPS (HSGPS) receiver, allowing subsequent identification
  
  of corridors, route lengths, and regional and inter-regional trips. The primary sensor is the HSGPS receiver. For the vehicular
  
  GPS-ATD, inertial sensing (MEMS gyro and accelerometers) is also provided to fill in the gaps during GPS outages and cold
  
  starts. To obtain vehicle sensor information, the GPS-ATD uses ZigBee wireless communications to the car computer On-Board
  
  Diagnostics connector (OBD-II). Following the design discussion, complete system testing, results, and user feedback are
  
  discussed. The report concludes with recommendations for future work related to the GPS-ATD and its use in the 2010 California
  
  Statewide Household Travel Survey.
