§ 1116.12 ANALYSIS AND LEVEL OF SERVICE.

   (a)   Capacity analyses shall be performed on each of the street and site intersections (signalized and unsignalized) in the study area. For each analysis period being studied, projected traffic volumes for site and non-site traffic shall be analyzed and used for capacity analysis for future conditions. LEVEL OF SERVICE (LOS) is the street’s ability to carry traffic in terms of average stopped delay per vehicle. The LOS analysis procedure set forth in the most recent issue of the Highway Capacity Manual, published by the Highway Research Board, shall be used to evaluate traffic operating conditions.

Table 1116 - Traffic Levels of Service1
Level of Service	Average Stopped Delay per Vehicle
A	5.0 seconds or less
B	5.1 to 15.0 seconds
C	15.1 to 25.0 seconds
D	25.1 to 40.0 seconds
E	40.1 to 60 seconds
F	More than 60 seconds

   (b)   The city’s goal for the operation of its roadways is to maintain the best level of service possible. An overall level of service of “D” shall be the minimum acceptable. The level of service for an intersection is computed as a weighted average of the vehicle delay. An intersection may have an overall LOS of or “D” and have individual movements of LOS “E” or “F.” As a result, all movements should be analyzed individually. Recommendations shall include modifications to reduce delay and increase capacity on the critical movements.
