Intelligent work zone (IWZ) systems use innovative technologies in real time to mitigate the negative impacts of work zones on the traveling public. The automatic queue detection (AQD) system is one … [Read more...] about Calibration and Validation Methodology for Simulation Models of Intelligent Work Zones
Traffic Queuing
Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data
Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has … [Read more...] about Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data
Queue Analysis at Work Zones From Field-Collected Data
Estimation of the capacity of work zones is vital to manage the possibility of traffic flows exceeding capacity and resulting in unbearable queues during work zone lane closures. A plethora of … [Read more...] about Queue Analysis at Work Zones From Field-Collected Data
Survey of Work Zone Practices and Validation of Highway Capacity Manual Work Zone Capacity Model
Capacity at work zones is one of the major factors affecting queueing at work zones. Different states within the United States use their own methodology in determining work zone capacities and when to … [Read more...] about Survey of Work Zone Practices and Validation of Highway Capacity Manual Work Zone Capacity Model
