What is Level of Service (LOS)?
Level of service (LOS) measures a driver’s experience on the road and at intersections, based on the speed and number of cars using the road. The LOS of a road is designated by a letter grade of A (free flow) to F (near gridlock).
A designation of A, B, or C represents free-flowing conditions. F is stop-and-go traffic. These scores are based on the highest congestion level on that roadway, even if it only occurs a few minutes a day.
A: Free flow. Low volumes and no delays.
B: Stable flow. Speeds restricted by travel conditions, minor delays.
C: Stable flow. Speeds and maneuverability closely controlled because of higher volumes.
D: Stable flow. Speeds considerably affected by change in operation conditions; high-density traffic restricts maneuverability, volume near capacity.
E: Unstable flow. Low speeds; considerable delays, volume at or slightly over capacity.
F: Forced flow. Very low speed, volumes exceed capacity, long delays with stop-and-go traffic.
