The applied trip distribution assumptions and resulting trips are shown in Table 4, which are based on the directionality of the 109 daily haul trucks that would visit the site rounded to the nearest five percent.

Generally, Level of Service A represents free flow conditions and Level of Service F represents forced flow or breakdown conditions. A unit of measure that indicates a level of delay generally accompanies the LOS designation. Operational Standard The San Joaquin County General Plan, 2016, states that the County’s standard is LOS C in general, or LOS D for minor arterials or roadways designated in the Congestion Management Plan (CMP), San Joaquin Council of Governments (SJCOG), as well as for Caltrans facilities such as SR-88. East Harney Lane, Jack Tone Road and Clements Road are classified as major collectors per the General Plan Figure TM-1. SR-88 is classified as a major arterial and both SR- 88 and Jack Tone Road are designated CMP roadways. Therefore, a standard of LOS D was applied to East Harney Lane/SR-88 and East Harney Lane/Jack Tone Road, while a standard of LOS C was applied to the remaining study intersections. Additionally, LOS D is considered acceptable for the study segment of SR-88 between East Harney Lane and Eight Mile Road, while LOS C is considered acceptable for the two East Harney Lane study segments.
