Semantic Enrichment of Spatio-temporal Trajectories for Worker Safety on Construction Sites
Existing literature reveals that major reasons of fatalities on construction sites are linked to mobility related issues such as unsafe human behaviors, difficult site conditions and workers striking … [Read more...] about Semantic Enrichment of Spatio-temporal Trajectories for Worker Safety on Construction Sites
Behavioral Measures for 48 Participants in Work-Zone Messaging Driving Simulation Study Collected in 2016 at the University of Minnesota
This study explored the impact of in-vehicle messages to alert drivers to events within a simulated work zone. Participants used a partial motion-based driving simulator made by Realtime Technologies, … [Read more...] about Behavioral Measures for 48 Participants in Work-Zone Messaging Driving Simulation Study Collected in 2016 at the University of Minnesota
Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
Increased delays and reduced speeds in work zones leads to congestion. This can be improved by optimizing the work zone length. The focus of this study is to model work zones using cellular automata … [Read more...] about Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
Locating Roadworks Sites via Detecting Change in Lateral Positions of Traffic Signs Measured Relative to the Ego-Car
Roadworks can be hazardous for both road workers and road users. Even with state-of-the-art safety measures in place, serious accidents do happen there, particularly when drivers do not heed roadwork … [Read more...] about Locating Roadworks Sites via Detecting Change in Lateral Positions of Traffic Signs Measured Relative to the Ego-Car
System to Provide Data on Risky Work-Zone Incidents
Work zone intrusions are a serious safety concern. Researchers at the University of Minnesota’s HumanFIRST Laboratory created a system for road crew workers to report work zone intrusions. The … [Read more...] about System to Provide Data on Risky Work-Zone Incidents
