1 Values shown are presented as two-way annual average daily volumes for levels of service and are for the automobile/truck modes unless specifically stated. This table does not constitute a standard and should be used only for general planning applications. The computer models from which this table is derived should be used for more specific planning applications. The table and deriving computer models should not be used for corridor or intersection des ign, where more refined techniques exist. Calculations are based on planning applications of the Highway Capacity Manual and the Trans it Capacity and Quality of Service Manual. 2 Level of service for the bicycle and pedestrian modes in this table is based on number of motorized vehicles, not number of bicyclists or pedestrians us ing the facility. 3 Buses per hour shown are only for the peak hour in the single direction of the higher traffic flow. * Cannot be achieved us ing table input value defaults. ** Not applicable for that level of service letter grade. For the automobile mode, volumes greater than level of service D become F because intersection capacities have been reached. For the bicycle mode, the level of service letter grade (including F) is not achievable because there is no maximum vehicle volume threshold us ing table input value defaults.
