Revised Traffic Impact Study March 27.2008 <br /> Proposed CEMEX Mining Site Page 6 <br /> The adjusted traffic volumes considering PCEs for use in the intersection analyses are presented in <br /> the following figures: <br /> L • Figure 16—PCE Existing Traffic Volumes <br /> • Figure 17—PCE Project Traffic Volumes - Haul Route 1 <br /> L • Figure 18—PCE Project Traffic Volumes - Haul Route 3 <br /> • Figure 19—PCE Approved Project Traffic Volumes <br /> • Figure 20—PCE Near-Term Traffic Volumes Without Project <br /> • Figure 21 —PCE Near-Term Traffic Volumes With Project-Haul Route 1 <br /> 6. • Figure 22 —PCE Near-Term Traffic Volumes With Project-Haul Route 3 <br /> • Figure 23 —PCE Cumulative Year 2025 Traffic Volumes Without Project <br /> L • Figure 24—PCE Cumulative Year 2025 Traffic Volumes With Project-Haul Route 1 <br /> • Figure 25 —PCE Cumulative Year 2025 Traffic Volumes With Project-Haul Route 3. <br /> For purposes of the two-lane road segment analyses, the 2000 Highway Capacity Manual establishes <br /> IN a PCE value of 1.7. For purposes of the multi-lane road segment analyses, weaving, merge, and <br /> diverge, the 2000 Highway Capacity Manual establishes a PCE value of 1.5. Therefore, the road <br /> segment analyses are based on the values presented in Figures 7 through 16 with the appropriate <br /> Ir PCE entered into the calculations. <br /> 6.0—TRAFFIC ANALYSES <br /> 6" 6.1 —Level of Service <br /> "Level of service" (LOS) is a qualitative measure describing operational within a traffic stream, <br /> based on service measures such as speed and travel time, freedom to maneuver,traffic interruptions, <br /> comfort, and convenience. LOS characteristics for unsignalized and signalized intersections are <br /> presented in Tables 2 and 3, respectively. LOS characteristics for road segments are presented in <br /> ` Table 4. <br /> Table 2 <br /> LLevel of Service Characteristics for Unsignalized Intersections <br /> Level of Service Description Average Vehicle Delay <br /> (seconds) <br /> A Little or no delay. 0-10 <br /> �.
