This report summarizes Phase Three of a long-term Intelligent Transportation Systems (ITS) research program by the Arizona Department of Transportation (ADOT) to study cooperative vehicle and infrastructure-based guidance technologies. ADOT's Arizona Transportation Research Center (ATRC) in Phoenix has conducted this research project as an in-house effort. Phase Three of Arizona's advanced-vehicle research, the 2002-03 winter seasons, was Year Five of the program. In four previous years, the project efforts focused on advanced lane positioning and predictive guidance technologies that required a complex roadway infrastructure component. This concluding Phase Three of the project, in contrast, has evaluated two commercial on-board driver-warning systems on seven snowplow routes across northern Arizona. |
