• Abstract:
  Traffic congestion mitigation is one of the key challenges that transportation planners and operations engineers face when
  
  planning for construction and maintenance activities. There is a wide variety of approaches and methods that address work
  
  zone impacts, starting with simple equations, over spreadsheets and deterministic methods, to high-level computer simulation
  
  software. Some of the widely used tools include CA4PRS, QuickZone, and VISUM. However, every model has its own
  
  limitations and assumptions that are dictated by the applied computational technique. These analysis tools may not fully
  
  capture the dynamic nature of drivers‟ responses to traffic management techniques and significant changes in the
  
  transportation network. In this case, performing analyses with a Dynamic Traffic Assignment (DTA) engine, or a similar
  
  traffic estimation method, may meet this need while providing additional analysis details (e.g. network, path, OD, and link
  
  analyses) for local engineers to justify their decisions/actions. At the same time, technical expertise, data management, and
  
  software licensing often become significant barriers for incorporating this type of analysis into every-day operations. This
  
  research presents a DTA based tool that is designed to overcome the existing limitations in work zone simulation and analysis.
