Traffic Study <br />Lexington Avenue Reconstruction <br /> <br /> <br />Alliant No. 118-0186.0 33 <br />April 18, 2019 <br />Table 9. Operations Analysis Summary – Preliminary Alternatives (2040 PM Peak Hour) <br />Alternatives 0, 1, & 2: <br /> <br />Alternatives 3, 4, & 5: <br /> <br />Results of the traffic operations analysis indicate that the Lexington Avenue corridor intersections <br />are expected to operate at overall LOS D or better under forecast year 2040 traffic volumes and <br />the various preliminary alternatives. Modeling indicates that the side-street approaches at the <br />Lexington Avenue / Enterprise-Big O Tires-Arby’s and Lexington Avenue / Shannon Square <br />intersections are expected to endure long delays and queues under alternatives 0, 1, 2, and 3. This <br />is primarily due to the difficulty of finding acceptable gaps to make side-street left-turn maneuvers <br />under peak hour volumes. It should be noted that unsignalized side-street right-turn maneuvers <br />would typically be expected to be made with minimal delay, except when blocked by queued <br />left-turning vehicles. Therefore, RIRO access may be acceptable at unsignalized intersections. <br /> <br />Lexington Avenue & I-694 WB Ramps C / E 30.3 / 60.9 C / D 26.2 / 45.4 C / D 28.7 / 53.1 <br />Lexington Avenue & I-694 EB Ramps C / E 24.9 / 67.2 C / D 21.1 / 50.6 C / D 21.2 / 41.3 <br />Lexington Avenue & Red Fox Road C / D 34.7 / 47.9 C / D 34.6 / 52.7 C / D 28.5 / 42.4 <br />Lexington Avenue & Lexington Station <br />Lexington Avenue & Target South <br />Lexington Avenue & Enterprise/Big O Tires/Arby's A / C 1.8 / 20.1 A / C 1.5 / 20.8 A / C 1.5 / 20.5 <br />Lexington Avenue & Grey Fox Road B / D 17.0 / 41.1 B / D 15.5 / 42.7 B / D 16.5 / 41.3 <br />Lexington Avenue & Shannon Square A / D 6.9 / 28.3 A / D 6.8 / 32.1 A / E 8.0 / 47.5 <br />Lexington Avenue & CR E D / E 48.8 / 74.5 D / E 48.8 / 74.5 D / E 48.8 / 74.5 <br />1: Lexington Avenue & Lexington Station consolidated with Lexington & Target South for Alternatives 0,1,2,3,4,&5 <br />A /D 7.5 /29.58.6 /29.2 A /D 7.3 /29.6 <br />Overall Intersection LOS / Worst Approach LOS <br />Overall Intersection Delay / Worst Approach Delay <br />ALT 0 ALT 1 ALT 2 <br />LOS Delay (s)LOS Delay (s)LOS Delay (s) <br />A /D <br />Intersection <br />Lexington Avenue & I-694 WB Ramps C / D 28.2 / 46.0 C / E 30.2 / 58.8 C / D 25.0 / 45.4 <br />Lexington Avenue & I-694 EB Ramps C / D 20.9 / 41.9 C / D 21.6 / 44.1 C / D 21.3 / 45.1 <br />Lexington Avenue & Red Fox Road C / D 28.8 / 47.9 C / D 26.9 / 41.4 C / D 27.8 / 41.8 <br />Lexington Avenue & Lexington Station <br />Lexington Avenue & Target South <br />Lexington Avenue & Enterprise/Big O Tires/Arby's A / D 2.1 / 33.9 A / A 1.5 / 9.6 <br />Lexington Avenue & Grey Fox Road B / D 16.6 / 41.2 C / D 21.0 / 41.8 <br />Lexington Avenue & Shannon Square A / F 8.5 / 52.4 A / C 4.5 / 15.6 <br />Lexington Avenue & CR E D / E 42.8 / 56.0 D / E 42.8 / 57.9 D / E 42.2 / 63.4 <br />3: Lexington Avenue & Shannon Square consolidated with Lexington & Grey Fox Road for Alternative 5 <br />2: Lexington Avenue & Enterprise/Big O Tires/Arby's consolidated with Lexington & Target South for Alternative 5 <br />/D <br />Intersection ALT 3 ALT 4 ALT 5 <br />LOS Delay (s)LOS Delay (s)LOS Delay (s) <br />B /D 15.6 /40.6 <br />Overall Intersection LOS / Worst Approach LOS <br />Overall Intersection Delay / Worst Approach Delay <br />7.8 /30.6 <br />A /D 6.7 /30.0 <br />A /D 8.3 /32.5 A
