Work Zone Capacity Estimation for High Truck Volume Routes in Arkansas: Predicting Highway Capacity through Work Zones With High Truck Volumes and Reduced Lane Geometry Based Upon Local Conditions
Work zones on freeways are estimated to contribute to nearly 24 percent of non‐recurring delay. Prior to 2010, the Highway Capacity Manual (HCM) provided limited guidance on vehicular capacity … [Read more...] about Work Zone Capacity Estimation for High Truck Volume Routes in Arkansas: Predicting Highway Capacity through Work Zones With High Truck Volumes and Reduced Lane Geometry Based Upon Local Conditions
Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones
The present study proposes a method for determining the capacity and measures of effectiveness of two-lane highway work zones. Therefore, a deterministic mathematical formulation was developed based … [Read more...] about Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones
Issues With Work Zone Free Flow Speed Computation in 6th Edition HCM and Proposed Improvements
Free flow speed (FFS) and capacity of work zones (WZ) directly affect queue length and delay in the WZ. The 6th Edition of Highway Capacity Manual introduced a new model to estimate WZ FFS and … [Read more...] about Issues With Work Zone Free Flow Speed Computation in 6th Edition HCM and Proposed Improvements
Estimating Construction Work Zones Capacity Using Deep Neural Network
Construction work zones are a major cause of traffic disruptions and delays on roadways. Thus, accurate estimation of traffic states within work zones would be beneficial to both road users and … [Read more...] about Estimating Construction Work Zones Capacity Using Deep Neural Network
Improving Work Zone Mobility Through Planning, Design, and Operations
This research project consists of a series of tasks intended to yield results that will better inform transportation agencies in their planning, design, and operations of freeway work zones. This … [Read more...] about Improving Work Zone Mobility Through Planning, Design, and Operations
