4.7 EXISTING TRAFFIC OPERATING CONDITIONS

To assess the traffic operating conditions of the street system in Sutter County, existing daily traffic count information was collected from both the State and the County. Using the existing ADT's, Levels of Service for primary roadways in Sutter County were evaluated. Tables 4.7-1 and 4.7-2 show the existing Levels of Service on the State Highways and County roadway segments. A graphical representation of the existing roadway Levels of Service are shown on Figure 4.7-1.

As indicated by Table 4.7-1, all state highway segments currently operate at LOS "E" or better. A review of Caltrans Route Concept and Development Reports (RCDR) for all state highway segments indicate all segments are within their respective concept LOS standard.

As shown in Table 4.7-2, all County roadways are currently operating at, or better than, the County minimum standard of LOS "D" or better.
