<br /> Notes: The Stockton General Plan does not provide thresholds for local roads.The"Existing"Area is generally located between 1-5 and
<br /> SR 99,and between Eight Mile Road and French Camp Road.Eight Mile Road is considered a"New"arterial due to lack of
<br /> existing development in the area.
<br /> Table 4.19-3.Level of Service Criteria for Freeway Merge and Diverge Areas
<br /> Level of Vehicle Density Operating characteristics
<br /> Service
<br /> A Less than or equal to 10 LOS A represents unrestricted operations.Density is low enough to permit smooth
<br /> merging and diverging,with very little turbulence in the traffic stream.
<br /> B Greater than 10 At LOS B,merging and diverging maneuvers become noticeable to through drivers,
<br /> Less than or equal to 20 and minimal turbulence occurs.
<br /> C Greater than 20 At LOS C,speed within the influence area begins to decline as turbulence levels
<br /> Less than or equal to 28 become much more noticeable.Both ramp and freeway vehicles begin to adjust their
<br /> speeds to accomplish smooth transitions.
