• Abstract:
  A work zone intrusion alert technology is a type of safety system that is used in a roadway work zone to alert ; field workers and secure time for them to escape when errant vehicles intrude into the work zone. Although ; such technologies have potential to significantly improve the overall safety of construction work zones, ; previous studies reported mixed findings, resulting in limited application of intrusion alert technologies. In ; response, the primary goal of this research study is to scientifically assess the effectiveness of currently ; available work zone intrusion alert technologies, and to provide recommendations for use of the technologies ; in future ODOT construction and maintenance work zones. To fulfill this goal, the research gathered ; information about work zone intrusion alert technologies, gained experiential input and advice from ODOT ; staff and industry practitioners, and tested technologies under controlled conditions and in active work zones. ; While sample sizes were limited, the findings from the study indicate that aspects of intrusion alarms via ; visual, audio, and haptic means can be effective warning mechanisms in a work zone. To improve the ; potential impacts of these technologies, this report identifies recommended minimum standards for each of the ; aforementioned means of alert. Implementation of the research results is expected to assist ODOT with ; enhancing the safety of motorists and workers in construction work zones on high-speed roadways.
