Innovative Work Zone Capacity Models from Nationwide Field and Archival Sources
Freeway work zone capacity has been the focus of significant research, but most studies were limited to specific geographic regions or work zone configurations or both. To date, no work zone … [Read more...] about Innovative Work Zone Capacity Models from Nationwide Field and Archival Sources
Incident Capacity Reduction on Four-lane Freeways Using Real World Data: Multilane Closures
One of the main goals in incident management is to reduce delay and queuing caused by an incident. Delay and queuing are among other things dependent on the road capacity, so an accurate estimate of … [Read more...] about Incident Capacity Reduction on Four-lane Freeways Using Real World Data: Multilane Closures
Work-Zone Traffic Operation and Capacity
In assessments of the impact of expressway lane closures on traffic flow, current practice generally involves an assumption of the nominal capacity per lane which varies, in some cases significantly, … [Read more...] about Work-Zone Traffic Operation and Capacity
Effects of Road Construction Intensity and Operations on Rural Freeway Work Zone Capacity
Capacity is affected by construction type and its intensity on adjacent open traffic lanes. The effect on capacity is a function of vehicles moving in and out of the closed lanes of the work zone, and … [Read more...] about Effects of Road Construction Intensity and Operations on Rural Freeway Work Zone Capacity
