Variable Speed Limit Systems
Driver Feedback on Monetary Penalty and Its Impact on Work Zone Speed
Across the nation, one work zone fatality occurs every 10 h (about 2.3 per day) and one injury, every 13 min (110 per day). Speed limit compliance in and around work zones concerns transportation … [Read more...] about Driver Feedback on Monetary Penalty and Its Impact on Work Zone Speed
Fault-Tolerant Variable Speed Limit Control for Freeway Work Zone
Freeway work zone can easily lead to traffic congestion which has detrimental effects on travel time and safety. By using the detected traffic states near work zone area, variable speed limit (VSL) … [Read more...] about Fault-Tolerant Variable Speed Limit Control for Freeway Work Zone
Variable Speed Limit for Freeway Work Zone with Capacity Drop Using Discrete-Time Sliding Mode Control
Freeway work zone with lane closure has a direct negative impact on travel time, safety, and environmental sustainability. The capacity drop at the onset of the congestion can also further reduce the … [Read more...] about Variable Speed Limit for Freeway Work Zone with Capacity Drop Using Discrete-Time Sliding Mode Control
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
Use of Portable and Dynamic Variable Speed Limits in Construction Zones
Utah Department of Transportation (UDOT) implemented dynamic management of portable variable speed limit (PVSL) technology to reduce regulatory speed limits through an active work space (AWS), and … [Read more...] about Use of Portable and Dynamic Variable Speed Limits in Construction Zones
