Quick. Zone — A Work Zone Delay Estimation and Analysis Tool Matthew H. Hardy Senior Transportation Engineer Mitretek Systems James J. Larkin Senior Transportation Engineer Mitretek Systems Karl E. Wunderlich, Ph. D. Senior Principal Analyst Mitretek Systems Slide http: //ops. fhwa. dot. gov/wz/workzone. htm

What is Quick. Zone? • Work Zone Delay Impact Analysis Tool – FHWA-sponsored – Developed by Mitretek Systems – Available for purchase at Mc. Trans ($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 Slide 2 http: //ops. fhwa. dot. gov/wz/workzone. htm

Quick. Zone 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 Slide 3 http: //ops. fhwa. dot. gov/wz/workzone. htm

Quick. Zone 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 4

Quick. Zone Partnership Program • Partnership Between the FHWA and State or Local DOT – Takes Advantage of Quick. Zone’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 – – Maryland SHA Pennsylvania DOT Ohio DOT North Carolina DOT – Wisconsin DOT – Washington DOT – Utah DOT Slide 17 http: //ops. fhwa. dot. gov/wz/workzone. htm

How Can Quick. Zone 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 Slide 18 http: //ops. fhwa. dot. gov/wz/workzone. htm
