Performance Measures Used in the DFW Region – How to Track and Report the M & O Investment and Results AMPO Management and Operations Work Group September 28-29, 2006

Performance Measures Examples Regional Modeled and Observed Freeway Corridor Observed Freeway and Arterial

Congestion: A Growing Problem

Blob Maps Parameters Percentage of Roadways Congested (LOS D, E or F) Model Output 0 to 30 Percent, not Congested 30 to 60 Percent, Moderately Congested Above 60 Percent, Severely Congested

Congestion Map Parameters Observed Data Moderate or Intermittent Congestion (30 – 50 mph or 45 – 60 pcplpm) Severe Congestion ( 60 pcplpm)

Relationship of Vehicle Density to Vehicle Speed Speed of Vehicles Density of Vehicles Low High LowHigh

Thoroughfare Assessment Program Data Collection System Analysis (including emission calculations, NCTCOG) Recommend Improvements (timing plans and low-cost capital improvements) Implementation and Fine-Tuning After Assessment Documentation of Results

Thoroughfare Assessment Program – Performance Measures Travel Time – Modeled/Observed Delay – Modeled/Observed Number of Stops - Modeled/Observed Average Speed – Modeled/Observed Emissions (VOC and NOx) – Modeled/ Post-Processed

Truck Lane Pilot Study Observed ITS Data Speed, Volume and Lane Occupancy Average Speed by Direction by Phase Percent Change in Volumes by Phase Average Speed by Lane by Phase

Next Steps for DFW Continue to Develop Inventory of P.M. Develop Regional Standard P.M. Continue to Track and Gather Data Develop a Regular Reporting Schedule Document Benefits of Projects
