SPR 782 Improving Worker Safety in Work Zones with Effective Proximity Sensing Technology

The project will synthesize SWZ technologies and analyze their benefits and challenges —specifically focusing on intrusion alert and motorist alert systems—based on their use by other highway agencies and the construction industry. These findings will then be tailored to fit the needs of the South Carolina Department of Transportation's (SCDOT’s) internal and contract workforce. To meet the research goals, the team will focus on three key objectives: (1) Investigate various intrusion alert technologies to identify those best suited for highway worker safety, motorist alert systems effective in work zones, and solutions that can reduce unsafe driving behaviors in South Carolina. (2) Assess at least three intrusion alert and three motorist alert technologies for suitability to the SCDOT, evaluating their capabilities, feasibility, and providing cost estimates for initial implementation and life cycle comparisons against current practices. (3) Evaluate compliance by workers in using these technologies and assess motorist response and behavioral changes prompted by driver-facing alert devices.
