Impact of Platooning Connected and Automated Heavy Vehicles on Interstate Freeway Work Zone Operations
Work zones pose mobility issues to the traveling public and safety challenges to travelers and road maintenance workers. These safety and mobility issues may be exacerbated by the presence of heavy … [Read more...] about Impact of Platooning Connected and Automated Heavy Vehicles on Interstate Freeway Work Zone Operations
Determining the Most Economical Work Zone Lengths for Rural Highway Rehabilitation Projects
Despite the wealth of research that has sought to understand the effects of highway work zones, very little definitive information is available concerning the determination of work zone length (WZL) … [Read more...] about Determining the Most Economical Work Zone Lengths for Rural Highway Rehabilitation Projects
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
Delay or Travel Time Information? The Impact of Advanced Traveler Information Systems on Drivers’ Behavior Before Freeway Work Zones
Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and … [Read more...] about Delay or Travel Time Information? The Impact of Advanced Traveler Information Systems on Drivers’ Behavior Before Freeway 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
