Multimodal Level of Service for Urban Streets Page 28 STEP 1 SELECT ANALYSIS METHOD For analysis of existing conditions for a facility, it is usually most accurate to measure performance in the field and then use that measured performance to compute LOS from those measurements. In this case the analyst should skip over the performance computation steps and focus only on the level of service computation steps, using their measured performance data as inputs to the LOS computations.

Multimodal Level of Service for Urban Streets Page 29 Exhibit 11 illustrates the segmentation of a two-block long street with 3 intersections into 2 eastbound segments and 2 westbound segments. Note that each segment starts downstream of the upstream intersection and terminates downstream of the downstream intersection.
