Improving the Effectiveness of Smart Work Zone Technologies
This project evaluates the effectiveness of sensor network systems for work zone traffic estimation. The comparative analysis is performed on a work zone modeled in microsimulation and calibrated with … [Read more...] about Improving the Effectiveness of Smart Work Zone Technologies
Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Traffic incidents are a major source of congestion in both urban and rural areas. Nationally, roughly 25% of total congestion is due to traffic incidents. Further, traffic incidents create unexpected … [Read more...] about Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Estimation of Arterial Work Zone Capacity Using Simulation
Numerous states have policies that provide guidance for the institution of short term lane closures on arterial streets based on capacity estimates, however it is not clear how the existing values … [Read more...] about Estimation of Arterial Work Zone Capacity Using Simulation
User Delay Costs Due to Work Zone Operations Near Echo Junction
With the increasing number of road rehabilitation projects across the United States, the need to reduce user costs due to congestion is more important than ever. The Utah Department of Transportation … [Read more...] about User Delay Costs Due to Work Zone Operations Near Echo Junction
Simulation Models for Assessment of the Impacts of Strategies for Highway Work Zones: Eight Case Studies Along Interstate Highways and State Routes in New England
As the National Highway System reaches the end of its serviceable life, transportation agencies increasingly need to focus on the preservation, rehabilitation, and maintenance of these roads. In light … [Read more...] about Simulation Models for Assessment of the Impacts of Strategies for Highway Work Zones: Eight Case Studies Along Interstate Highways and State Routes in New England
