Evaluating Mobility Impacts of Construction Work Zones on Utah Transportation System Using Machine Learning Techniques
Construction work zones are inevitable parts of daily operations at roadway systems. They have a significant impact on traffic conditions and the mobility of roadway systems. The traffic impacts of … [Read more...] about Evaluating Mobility Impacts of Construction Work Zones on Utah Transportation System Using Machine Learning Techniques
Enhancing Work Zone Capacity by a Cooperative Late Merge System Using Decentralized and Centralized Control Strategies
This paper explores the efficiency of a novel merging system based on a cooperative late merge strategy (CLMS) to mitigate the capacity reduction in work zones due to lane closure. Cooperative late … [Read more...] about Enhancing Work Zone Capacity by a Cooperative Late Merge System Using Decentralized and Centralized Control Strategies
Queue Analysis at Work Zones From Field-Collected Data
Estimation of the capacity of work zones is vital to manage the possibility of traffic flows exceeding capacity and resulting in unbearable queues during work zone lane closures. A plethora of … [Read more...] about Queue Analysis at Work Zones From Field-Collected Data
Survey of Work Zone Practices and Validation of Highway Capacity Manual Work Zone Capacity Model
Capacity at work zones is one of the major factors affecting queueing at work zones. Different states within the United States use their own methodology in determining work zone capacities and when to … [Read more...] about Survey of Work Zone Practices and Validation of Highway Capacity Manual Work Zone Capacity Model
Evaluation of DOTD’s Existing Queue Estimation Procedures
Louisiana Department of Transportation and Development (DOTD) requests that freeway lanes should not be closed for construction work during hours when capacity exceeds 1,309 pcphpl. It is not known … [Read more...] about Evaluation of DOTD’s Existing Queue Estimation Procedures
