Central to the effective design of work zones is being able to understand how drivers behave as they approach and enter a work zone area. States use simulation tools in modeling freeway work zones to … [Read more...] about Validating the Performance of the FHWA Work Zone Model Version 1.0: A Case Study Along I-91 in Springfield, Massachusetts

Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
Increased delays and reduced speeds in work zones leads to congestion. This can be improved by optimizing the work zone length. The focus of this study is to model work zones using cellular automata … [Read more...] about Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
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
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
Safety Impacts of Queue Warning in a Connected Vehicle Environment
Queue warning systems (QWSs) have been implemented to increase traffic safety by informing drivers about queued traffic ahead so that they can react in a timely manner to the queue. Existing QWSs rely … [Read more...] about Safety Impacts of Queue Warning in a Connected Vehicle Environment
Evaluation of Variable Advisory Speed Limits in Congested Work Zones
The effectiveness of variable “advisory” speed limit (VASL) systems in congested urban work zones was investigated. Except for one publication, all previous studies focused on regulatory speed limit … [Read more...] about Evaluation of Variable Advisory Speed Limits in Congested Work Zones
