Performance Measures Examples Regional Modeled and Observed Freeway Corridor Observed Freeway and Arterial
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 (<30 mph or > 60 pcplpm)
Relationship of Vehicle Density to Vehicle Speed High Speed of Vehicles Low Low High Density of Vehicles
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
