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
