Wireline Communications Workshop for Intelligent Transportation System Applications (0-4969-S)

This project summary report summarizes the research performed in Texas Department of Transportation (TxDOT) Project 0-4969. The project developed a communications design methodology for assessing communications needs for intelligent transportation system (ITS) deployments. It also produced a reference guidebook and training workshop materials concerning wireline communications concepts and technologies. Researchers conducted a literature survey, identified the most common technology solutions utilized in the ITS arena, and provided detailed information on each technology choice. Of particular usefulness to engineers are the cross-technology tabulations of critical aspects of the communications solutions. A main result of the project is a design/evaluation methodology, which covers both data and video applications. This methodology provides TxDOT engineers with a systematic procedure for device accounting, bandwidth determination, evaluation of latency effects, suggested communications solutions, and typical design and deployment scenarios. The project summary report also describes recommendations for future workshops.
