<br />Synchro Intersection Operations Model <br /> <br />The Synchro database was developed for over 100 signalized and unsignalized <br />intersections on City streets. The database was coded for the three scenarios <br />(Existing, Approved, and General Plan Buildout) and 2 peak hours (AM and PM). <br /> <br />City of Pleasanton staff provided the existing base traffic counts and intersection <br />data to determine existing base year intersection levels of service. The Synchro <br />database requires for each signalized intersection: <br /> <br />. Signal phasing and controller settings <br />. Intersection lane geometry, <br />. Turn pocket lengths, and <br />. Turning movement forecasts. <br /> <br />The turning movement forecasts for Approved and General Plan Buildout are <br />obtained from the City travel demand tool as described above. The forecasted <br />turning movements are ported from the demand tool to the micro-simulation tool in <br />comma delimited files. The Synchro portion of the microsimulation tool is used to <br />compute intersection delay, level of service, and to optimize signal controller <br />settings and signal coordination settings. <br /> <br />The following intersection based roadway network improvements were assumed in <br />the evaluation of "Buildout" conditions: <br /> <br />. Bernal Avenue at Case/Old Bernal - widen west side of street to add a <br />southbound right turn only lane on Old Bernal Avenue <br /> <br />. Valley Avenue at Busch Road - widen Busch Road to provide a second right <br />turn lane to Valley Avenue <br /> <br />. Bernal Avenue at Valley Avenue - convert eastbound right turn only lane <br />into a through/right option lane <br /> <br />. Bernal Avenue at Angela Street - right turn only from Angela during peak <br /> <br />. Bernal Avenue at Meadowlark widening associated with Arroyo Del Valle <br />bridge widening <br /> <br />. Bernal Avenue at Puerto Vallarta - right turns only from Puerto Vallarta <br />during peak hours <br /> <br />. Bernal Avenue at Vineyard Avenue widening associated with Arroyo Del <br />Valle bridge widening <br /> <br />. First Street at Vineyard/Ray - convert east/west to protected/permissive left <br />turn phasing <br /> <br />. Foothill Road at Canyon Way - convert #1 southbound through into third left <br />turn lane, restripe eastbound to create triple left turn, widen eastbound <br />Canyon Way to receive traffic from three left turn lanes <br /> <br />City of Pleasanton <br />Travel Demand Forecasting and Ml:cro-Simulation Models <br /> <br />Page 14 <br />January 23, 2007 <br />
