  1. TMC and Quality Assurance Quality Control TRANSPO Conference October 29, 2012 Joseph Snyder

  2. What is Quality Assurance Quality Control (QA/QC) • Quality Assurance • Activities Implemented to Meet Performance Metrics • Sets Standards • Quality Control • Process for Reviewing Performance • Includes Inspections or Review Process

  3. Why do we need QA/QC? • For Accountability, Standards, and Review Process Performance Metrics = Accountability = Excellence

  4. TMC Overview • Roadways Managed • 81 miles of Limited/Controlled Access • 125 miles of Arterials • Field Equipment • 22 Ramp Signals • 237 CCTV • 317 Detector Stations • 108 DMS

  5. TMC Overview • Performance Metrics • <2:00 min. to confirm (1:42) • <2:00 min. to dispatch (0:56) • <5:00 min. to Disseminate Information (2:27) • <7:00 min. for notification (1:11) • <0.59% errors (0.30%) • >95% DMS Efficiency (99.77%)

  6. TMC Overview • Standard Operating Guidelines • Control Management • TMC Systems • Road Rangers Coordination • Event Management (EM) • DMS • System Monitoring & Reporting • Express Lanes • Ramp Signal

  8. QA/QC Process

  9. Components • Review based on Event Chronology • Checks based on Software Data Structure • Data pulled directly from database • Performance Metric based on data • Reports validates the QA/QC process • Automatically checks events • Assists the review process by allowing Event Checker results to be viewed and processed • Stores results in the database • Check a Single Event • Performance Reports

  10. Mechanism Process Events page has four Components: • Event Filter • Checks • Operator Comments • Reviewer Comments

  11. Reporting • Lane Blockage • Non-Lane Blockage • Performance by Operator • Operator Output • Error Categories • Operator and Category Trends

  12. Benefits • Enhanced Productivity and Accountability • Reduced Errors by 47.3% • Clearly Communicates Performance Goals • Develops Consistence Performance • Tracking Performance Trends • Indentifying Training Needs • Work Load Analysis • Early Identification of Performance Problems • Celebrate Accomplishments
