Abstract:

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.
