<br />The p.m, peak hour traffic volumes for the three scenarios were used to perform capacity <br />analyses at the ten critical intersections, The level of service for the signalized intersections <br />was estimated using Synchro computer software. The unsignalized intersection level of <br />service was estimated using the unsignalized intersection module of the Highway Capacity <br />Software. (Note: The Spring 2001 analysis was conducted with an older release of the <br />software, then either February 2000 analysis or the current addendum) <br /> <br />Table 21-2 summarizes the level of service for the signalized intersections. Level of service <br />D is generally considered acceptable operating conditions. As table 21-2 presents, no level <br />of service difficulties are expected at any of the five signalized intersections. In addition, all <br />movements at the five intersections are expected to operate at LOS D or better in the 2004 <br />p.m, peak hour under the currently proposed development concept. <br /> <br />TABLE 21-2 <br /> <br /> . . ea our eve s 0 ervlce or 12na lze ntersectlOns <br /> 2004 Level of Service by Development Scenario <br /> With With With Spring 2001 With Currently <br />Intersection Development Development Proposed Proposed <br /> Approved in 1997 Approved in Development Development <br /> February 2000 <br />Cleveland Ave 1 D D D D <br />Co.

All intersections are expected to provide level of service D or better operations <br />under all 2004 scenarios, with the exception of the North Centre Pointe Drive intersection <br />with Cleveland A venue. The high volume of left turns expected from North Centre Pointe <br />Drive to northbound Cleveland Avenue will likely cause the west approach of the <br />intersection to operate at level of service F in the 2004 p.m, peak hour under the current <br />proposed development concept. <br /> <br />Environmental Assessment Worksheet <br />Centre Pointe Business Park <br /> <br />Page 19 of 29 <br />
