TABLE 3.6 <br /> INCREASE IN EXISTING VOLUMES DUE TO PROJECT TRAFFIC <br /> Increase in Existing <br /> 2-way PM Peak Hour Volumes <br /> Roadway Due to Project Traffic <br /> Mariposa Road (west of Austin) + 4% (from 435 to 454 VPH(a)) <br /> Mariposa Road (east of Austin) + 2% (from 495 to 505 VPH) <br /> Arch Road (west of Austin) +17% (from 58 to 68 VPH) <br /> Austin Road (south of Arch) + 4% (from 84 to 87 VPH) <br /> Austin Road (Arch to Mariposa) +24% (from 120 to 149 VPH) <br /> (a) VPH = Vehicles per hour <br /> on some roads, this is due to their existing low volumes. Project <br /> traffic increases would, in general , be low and could be accommodated <br /> well within the available capacities of all nearby roads. <br /> Table 3.2 shows that project traffic would not produce any <br /> measurable change in level of service at either the Mariposa/Austin or <br /> Austin/Arch intersections. All turn movements would remain at PM peak <br /> hour LOS A operation with the exception of the northbound Austin Road <br /> left turn to Mariposa Road, which would remain LOS B. Neither <br /> intersection would come close to meeting peak hour signal warrant <br /> criteria levels with the addition of project traffic. <br /> While analysis indicates that project traffic could well be <br /> accommodated within available roadway and intersection capacities, the <br /> significant number of project trucks would produce safety concerns at the <br /> project access and the Mariposa/Austin intersection due to the high <br /> prevailing speeds of ambient traffic and the extended times required for <br /> project trucks to accelerate from stopped conditions or to decelerate for <br /> 3-32 <br /> 101-32.R3 4/10/89 <br />
