Using Driver State Detection in Automated Vehicles
The next several years will bring a large increase in automated vehicle capabilities. High levels of automation will require bi-directional transfers of control between the driver and vehicle. These … [Read more...] about Using Driver State Detection in Automated Vehicles
The Sooner the Better: Drivers’ Reactions to Two-Step Take-Over Requests in Highly Automated Driving
Driving behavior after take-over requests (TORs) is one of the most popular subjects in human factors re-search on highly automated driving. Many studies utilized one-step TOR procedures to prompt … [Read more...] about The Sooner the Better: Drivers’ Reactions to Two-Step Take-Over Requests in Highly Automated Driving
Peripheral Monitoring of Traffic in Conditionally Automated Driving
Conditionally automated vehicles (level 3) allow drivers to engage in visual, non-driving related tasks (NDRTs) while the automation is active. System limits require drivers to reengage in the dynamic … [Read more...] about Peripheral Monitoring of Traffic in Conditionally Automated Driving
Evaluation of Green Lights on TMAs
The use of green versus traditional amber lights on Truck Mounted Attenuators (TMAs) was investigated to see if their use could help to improve safety in mobile work zones. Four light color … [Read more...] about Evaluation of Green Lights on TMAs
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
