LoS

Comments

1

0-2

Primarily free flow- movement at average travel speeds usually about 70% of the free flow speed for the key corridors.

2

3-4

Small increases in traffic causing substantial increase in approach delay and hence, decrease in arterial speed.

3

5-6

Significant approach delays and average travel speed of 1/3 the free flow speed or lower. Such conditions causing a combination of one or more reasons such as high signal density, extensive queuing at critical intersections and inappropriate signal timing.

4

7-8

Key corridors at extremely low speeds below 1/3 to 1/4 of the free flow speed. Intersection congestion is likely at critical signalized locations, with high approach delays.
