120 <br /> Emerson Waldorf School <br /> Traffic Impact Analysis <br /> Currently there are no Town of Chapel Hill projects scheduled for construction in <br /> the project study area. Because of this, no adjustments were made to the <br /> existing area lane configuration. All analyses will be conducted using the existing <br /> configurations. <br /> confi <br /> lane g <br /> III. Project Conditions <br /> The site generation potential of the proposed development was determined using <br /> the trip generation rates projected by the NCDOT s Municipal and Scho <br /> ol <br /> Transportation Assistance's (MSTA) school calculator. The approxima <br /> te numb <br /> er <br /> of students (350) was used to estimate the traffic generated during the AM and <br /> (school) PM peak hours. It should be noted that the MSTA school calculator <br /> provides only the peaking characteristics of the school. While the AM peak hour <br /> me as the <br /> AM peak hour for the <br /> trips generated by the schoo <br /> l occur at the <br /> same time <br /> p g not <br /> hour gene <br /> rated tr <br /> ips s do <br /> PM peak p <br /> project study area roadway facilities, the p g <br /> correspond with the peaking characteristics of the project study area roadway <br /> facilities. The school's PM peak hour will occur at approximately 2:30 — 3:30 <br /> p.m., whereas the PM peak hour of the project study area roadway facilities <br /> occurs between 4:00 p.m. — 6:00 p.m. For this reason, PM traffic was analyzed <br /> during the school's PM peak period (2:00 p.m. — 4:00 p.m.). AM trips generated <br /> totaled 372 vehicles with 221 vehicles entering and 152 vehicles exiting. PM trips <br /> generated totaled 211 vehicles with 94 vehicles entering and 117 vehicles <br /> exiting. <br /> Because the existing MSTA school calculator volumes closely resembled the <br /> existing traffic data collected (see Table ES-1 below), it was assumed (for <br /> purposes of analysis) that the MSTA calculator would provide an accurate <br /> representation of future on-site trips and on-site queuing. Therefore, trips <br /> generated by the MSTA calculator were used for all on-site Condition 3 analyses. <br /> The net differences in trips between the future and existing trips calculated by the <br /> MSTA calculator were applied to the traffic network for all off-site Condition 3 <br /> analyses. <br /> Table ES-1 summarizes the estimated traffic generation for the proposed <br /> development during the AM and (school) PM peak hour. No attempt was made to <br /> reduce the number of trips by a transit factor (due to the lack of accessible bus <br /> routes in the area), nor were the trips reduced due to pass-by trips. A heavy <br /> vehicle percentage of two percent was calculated by the MSTA school calculator <br /> and assumed for the purposes of this analysis. Existing peak hour factors were <br /> used for analysis due to the fact that existing school trips are currently using the <br /> same network as commuter trips. <br /> ES-3 Q P <br /> i 1 R ^.h1A 14IIci <br />
