Traffic Impact Assessment of Moving Work Zone Operations
Road maintenance activities involve both short-term stationary work zones and moving work zones. Moving work zones typically involve striping, sweeping, pothole filling, shoulder repairs, and other … [Read more...] about Traffic Impact Assessment of Moving Work Zone Operations
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
Modeling Freeway Work Zones with Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
This study developed a validation procedure for a dynamic traffic assignment—based mesoscopic simulator and identified its relevant data requirements. Model inconsistencies at the network level can be … [Read more...] about Modeling Freeway Work Zones with Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
Integrating Activities Risk and Traffic Microsimulation Data for Temporal Risk Assessment in Construction Work Zones: A Proof of Concept
Construction work zones impose mobility constraints and remain major contributors toward incidents on our highways. Pro-active hazard identification and risk assessment is necessary in order to … [Read more...] about Integrating Activities Risk and Traffic Microsimulation Data for Temporal Risk Assessment in Construction Work Zones: A Proof of Concept
