Cemex Vernalis Warn/Mining and Reclamation Project levels of service (with corresponding ranges of average vehicle delay)have been established, from LOS A(little or no delay)to LOS F(very long delays). Level of service characteristics for — unsignalized intersections are defined in the 2000 Highway Capacity Manual published by the Transportation Research Board and are presented in Table 4.4-1. — The San Joaquin County Guidelines for the TABLE 4.4-1 Preparation of Traffic Impact Studies indicates LEVEL OF SERVICE CHARACTERISTICS FOR LINSIGNALIZED INTERSECTIONS all County roadways shall operate at LOS C or better(except in a City sphere of influence Average Level of Vehicle Delay where the City has adopted LOS D); Service Description (Seconds) _ intersections shall operate at an overall LOS D A Little or no delay 0-10 or better on minor arterials and roadways of B Short traffic delays >10-15 higher classification;and LOS C on all other C Average traffic delays >15-25 — roads;all freeways and State highways shall D Long traffic delays >25-35 operate at LOS D. The Caltrans Guide for the E Very long traffic delays >3550 Preparation of Traffic Impact Studies indicates F Stop-and-go conditions >50 that Caltrans endeavors to maintain a target level of service at the transition between LOS C and LOS D, which effectively requires that an LOS C or better be maintained. The results of the existing intersection level-of-service calculations are shown in Table 4.4-2, and the analysis output is on-file and available for review at the San Joaquin County offices. Levels of — service are presented for each intersection approach from which movements are controlled by stop signs; the level of service for the intersection as a whole is not defined because the major street traffic is not required to stop.The levels of service were determined using the computer program Synchro 6,which is based on the 2000 Highway Capacity Manual procedures for calculating levels of service and which is listed in the Caltrans Guide for the Preparation of — Traffic Impact Studies as a commonly-used program. The results of the existing road segment level-of-service analyses are shown in Table 4.4-3. The _ Florida Department of Transportation has published tables correlating peak-hour volumes of roadway segments with levels of service. For this analysis,the table titled"Table 4-6, Generalized Peak Hour Two-Way Volumes for Florida's Urbanized Areas"(Florida Department — of Transportation, 2002)was used. The table is included in Appendix C. Freeway weaving and ramp junction analyses were performed at the study freeway interchanges. — Those analyses evaluated the effect of traffic at the intersections of on/off ramps and mainline freeway segments and determined resulting levels of service at these locations. The analysis was performed using HCS2000 computer program for the future-with-project conditions at the study — locations to identify the worst-case conditions based on the projected traffic. The analyses resulted in LOS C or better for all future-with-project conditions. The analysis sheets are on-file and available for review at the San Joaquin County offices located at 1810 East Hazelton Avenue, Stockton, California.
