TMC and Quality Assurance Quality Control
What is Quality Assurance Quality Control (QA/QC) Quality Assurance
– Activities Implemented to Meet Performance Metrics
– Sets StandardsQuality Control
– Process for Reviewing Performance
– Includes Inspections or Review Process
Why do we need QA/QC?
For Accountability, Standards, and Review Process
Performance Metrics = Accountability = Excellence
Quality Assurance Quality Control
Focus on processes Focus on outputsImproving production processes Sampling & checking outputs
Targets the whole organization Targets activities
Emphasizes the customer Emphasizes required standards
Quality is built into the product Errors are identified
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
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%)
TMC Overview
Standard Operating Guidelines– Control Management– TMC Systems– Road Rangers Coordination– Event Management (EM)– DMS– System Monitoring & Reporting– Express Lanes – Ramp Signal
