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 Freeway Work Zone Capacity Distribution Based on Logistic Speed-Density Models
Speed-volume-density relationship and capacity are key elements in modelling traffic operations, designing roadways, and evaluating facility performance. This paper uses a modified five-parameter … [Read more...] about Predicting Freeway Work Zone Capacity Distribution Based on Logistic Speed-Density Models
Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
In addition to closed merge lanes as physical bottlenecks of work zones, traffic oscillations caused by merging vehicles at multiple locations could reduce work zone capacity. This study took a … [Read more...] about Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
Capacity Models for Long-Term and Short-Term Freeway Work Zones in Germany
The paper presents results from a comprehensive study of work zone capacity on German freeways. A large number of long-time work zones with and without a reduction of the number of lanes as well as … [Read more...] about Capacity Models for Long-Term and Short-Term Freeway Work Zones in Germany
