<br />I <br />I. <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />.- <br />I <br />I <br />I <br />I <br />I <br />I <br />I. <br />I <br />I <br /> <br />Roadway Improvements <br /> <br />In addition to the roadway improvements assumed in the 2005 No-Build condition, the <br />2005 Build condition assumes that existing Guidant Drive North will be turned over to the <br />City and will become a public street requiring the street to be modified to meet the City of <br />Arden Hills public street design standards. These improvements will likely require a traffic <br />signal to be added to the intersection of Guidant Drive North and Lexington Avenue. <br />Traffic signal timing was also assumed to be optimized along Lexington Avenue to <br />account for the higher volumes of traffic being experienced on the roadway network due to <br />the Guidant Campus site growth. The roadway geometry for the 2020 Build conditions are <br />the same as the 2005 Build conditions, with the addition of a north-south connection being <br />extended north of CR 96 to CR I. This improvement was also assumed in <br />the 2020 No-Build. <br /> <br />Traffic Operations Analysis <br /> <br />Tables II and 12 display the results of the signalized and unsignalized intersection analysis <br />for the 2005 and 2020 Build traffic conditions. With limited public improvements planned <br />between 2005 and 2020 and traffic volumes estimated to increase, the LOS at roadways <br />will continue to decline and the majority of intersections will experience a LOS E or F by <br />2020. <br /> <br />TABLE 11 <br />FUTURE BUILD A.M.
