what is quickzone
What is QuickZone?
  • Work Zone Delay Impact Analysis Tool
    • FHWA-sponsored
    • Developed by Mitretek Systems
    • Available for purchase at McTrans ($200)
  • Microsoft Excel-based Application
  • Open Source Code for the Ability to Customize
  • Targeted at State and Local Traffic Construction Staff, Operations and Planning, and Construction Contractors
quickzone capabilities
QuickZone Capabilities
  • Quantifies corridor delay resulting from capacity decreases in work zones
  • Identifies delay impacts of alternative construction phasing plans
  • Supports Trade-Off Analyses between construction costs and delay costs
  • Considers Alternate Phasing Schedules:
    • Location along mainline
    • Time-of-day (peak vs. off-peak)
    • Season (summer vs. winter)
  • Assesses Impacts of Delay Mitigation Strategies:
    • E.g., Variable message sign deployments
    • Signal retiming on detour routes

QuickZone Analysis Process

Little Bras d’Or Bridge

Highway 105

Gerard Kennedy, P.Eng

Project Engineer, NS DOT&PW

  • Key bridge under repair
  • Capacity limited because of two-way, single lane operations
  • Work coincided with peak of travel season
  • Significant community concern about delays

quickzone partnership program
QuickZone Partnership Program
  • Partnership Between the FHWA and State or Local DOT
    • Takes Advantage of QuickZone’s Open Source Code
  • Designed to:
    • Further Improve the Software
    • Provide State and Local DOT with a Tool that Best Meets their Needs
  • Current Partners
  • Wisconsin DOT
  • Washington DOT
  • Utah DOT
  • Maryland SHA
  • Pennsylvania DOT
  • Ohio DOT
  • North Carolina DOT
how can quickzone be customized
How Can QuickZone be Customized?
  • State-specific queue-length estimation
  • Additional mitigation strategies
  • More detailed detour route volume assessment
  • Custom capacity reduction for work zones
  • Different calculations for user delay, queue estimation or cost analysis
  • Ability to import networks from other transportation modeling and simulation packages
