Feasibility of Lane Closures Using Probe Data
To develop an adequate traffic operations management and congestion mitigation plan for every roadway maintenance and construction project requiring lane closures, transportation agencies need … [Read more...] about Feasibility of Lane Closures Using Probe Data
Evaluation of Traffic Control Options in Work Zones
Lane closures for work zones along freeways produce bottlenecks. These bottlenecks are problematic due to loss of capacity and excessive lane changes, which impact the facility performance represented … [Read more...] about Evaluation of Traffic Control Options in Work Zones
Optimizing the Planning of Highway Work Zones to Maximize Safety and Mobility
Highway work zones create potential risks for both traffic and workers in addition to traffic congestion and delays that result in increased road user delay, traffic crashes, and vehicle emissions. … [Read more...] about Optimizing the Planning of Highway Work Zones to Maximize Safety and Mobility
A Smart Highway Work Zone Merge System Enabled by Connected Vehicles
Typical traffic control and operations at work zones usually are not very effective in mitigating the work zone bottleneck. A major reason is that the common early merge behaviors limits utilizing the … [Read more...] about A Smart Highway Work Zone Merge System Enabled by Connected Vehicles
Variable Speed Limit Control for Delay and Crash Reductions at Freeway Work Zone Area
Improving operational efficiency and safety on freeway segments has long been recognized as a priority in traffic communities. This study presents a comprehensive variable speed limit (VSL) control … [Read more...] about Variable Speed Limit Control for Delay and Crash Reductions at Freeway Work Zone Area
