A Handheld Terminal for Field Elements

This report documents the research project entitled: “A Handheld Terminal for Field Elements.” The primary goal of this research was to design and develop a Handheld Terminal (HHT) kit for the purpose of diagnosing and configuring field element devices. The HHT was developed based on ubiquitous commercial off-the-shelf (COTS) hardware; selection of this hardware was an important early task in the project. Most of the subsequent research in this study involved development of the software package. The HHT kit was programmed to interface with closed-circuit TV (CCTV) cameras and changeable message sign (CMS) hardware, using standardized protocols for each. The HHT also provides a console app. The goal of the HHT kit is to give Caltrans field personnel a more ruggedized, robust system to deal with the specific task of diagnosing and configuring traffic operations field elements. This will enable employees to get their work done faster, safer, and with dramatically reduced chances for loss of potentially expensive equipment. The system will also assist Caltrans in reaching its goals of System Performance, Stewardship, and Efficiency.
