67 <br /> Triangle Regional o's F'r of e c 11'.)eveloIxii-neint Scope of Work <br /> Downtown Durham — Focused along Pettigrew Street from Ninth Street/NC 147 to Alston <br /> Avenue. <br /> Erwin Road—Along Erwin Road from Fifteenth Street to Cameron Boulevard. <br /> South Square/University Drive—Starting at the Cornwallis Road Crossing and continuing through <br /> the University Drive area. It is anticipated that only the D3 alternative will be examined as it was <br /> selected as the LPA in an earlier phase. <br /> Gateway/Patterson Place Area — Beginning with the crossing of Garrett Road and continuing <br /> through Leigh Village. <br /> NC 54/Meadowmont Village Area — This sub-area will begin west of Leigh Village and continue <br /> through the Hamilton Station/Finley Golf Course Road crossing. It is assumed that two build <br /> scenarios will need to be developed; one for Alternative C1 and one for Alternative C2. <br /> Manning/UNC Chapel Hill Area —This will begin with the crossing of Old Mason Farm Road and <br /> continue through to the UNC Hospitals station. <br /> Base Year Model Data Collection <br /> The project team will collect data necessary to develop the VisSim micro-simulation models. This data <br /> will include, but is not necessarily limited to the following: <br /> * Aerial photography <br /> Contour data <br /> Traffic signal plans <br /> Relevant coordination plans <br /> All existing and relevant traffic counts <br /> Initial Base Year VisSim Model Data Development <br /> Coding of the VisSim model along appropriate sections of the corridor will begin by creating a base <br /> network over relevant aerial photography and contour data. The network will be verified initially and <br /> will be refined for what will be needed for the micro-simulation. This will include, but is not necessarily <br /> limited to the following: <br /> Coding of lanes and geometry <br /> Adding contour data <br /> Adding in traffic signals and subsequent timing and coordination plans <br /> Developing and coding measures of effectiveness (MOE's) <br /> Preforming a QA/QC check to ensure that data accurately matches base field conditions <br /> Once completed a geometrically accurate base year micro-simulation model will have been created.This <br /> model will at this point have no traffic data. <br /> Durlhaiuru-Or-ain e ll,,,'[glnt IRaH °I°uransiit Project O June 2013 J 4-2 DRAFT <br />
