Predicting Traffic Dynamics with Driver Response Model for Proactive Variable Speed Limit Control Algorithm
Variable Speed Limit (VSL) control contributes to potential crash risk reduction by suggesting a suitable dynamic speed limit to achieve more stable and uniform traffic flow. In recent studies, … [Read more...] about Predicting Traffic Dynamics with Driver Response Model for Proactive Variable Speed Limit Control Algorithm
Effects of Mounting Height, Offset Distance, and Number of Light Towers on Drivers’ Visual Performance and Discomfort Glare in Work Zones
Portable light towers are a significant source of glare to motorists entering a work zone. Although existing research has evaluated the effect of light tower orientation on visibility and glare, the … [Read more...] about Effects of Mounting Height, Offset Distance, and Number of Light Towers on Drivers’ Visual Performance and Discomfort Glare in Work Zones
Analysis of the Sensitivity of Heart Rate Variability and Subjective Workload Measures in a Driving Simulator: The Case of Highway Work Zones
Heart rate variability and subjective workload measures are extensively used to determine workload during driving. However, the sensitivity of heart rate and workload measurements in simulated driving … [Read more...] about Analysis of the Sensitivity of Heart Rate Variability and Subjective Workload Measures in a Driving Simulator: The Case of Highway Work Zones
Effectiveness of Visual Warnings on Young Drivers Hazard Anticipation and Hazard Mitigation Abilities
Previous studies have demonstrated that young drivers fail both to scan for and mitigate latent hazards mostly due to their cluelessness. This study aims to investigate whether these skills could be … [Read more...] about Effectiveness of Visual Warnings on Young Drivers Hazard Anticipation and Hazard Mitigation Abilities
In-Vehicle Work Zone Messages
Work zones present an increased risk to drivers and the work crew. To mitigate these risks, this study investigated the potential effects of in-vehicle messages to communicate work zone events to the … [Read more...] about In-Vehicle Work Zone Messages
