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 • 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
