<br />. 1-694 is a four-lane principal arterial interstate highway providing access to the Guidant a <br />Campus via the Lexington Avenue interchange. The existing ADT on 1-694 is 99,000 .. <br />(between the Hamline Avenue and Lexington Avenue interchanges). <br /> <br />There are two roadways within the AUAR study boundary that provide for internal site <br />circulation - Fernwood Drive and Guidant Drive North. These roadways also provide <br />access to businesses and a park (Cummings Park) north of the study area, just north of <br />Guidant Drive North. Fernwood Drive is currently a two-lane public roadway that runs <br />north-south and bisects the existing campus, Guidant Drive North is currently a private <br />roadway that runs east-west along the study area's northern boundary. <br /> <br />Existing Traffic Operations <br /> <br />The capacity of nearly every roadway segment is determined at the nodes of each end of the <br />segment. Capacity is hardly ever restricted along the segment itself. In the case of a <br />freeway, the nodes are the interchanges. For an arterial roadway, the nodes are the <br />intersections. It is at these interchanges and intersections where the operational issues and <br />capacity deficiencies of a roadway will be observed. <br /> <br />A traffic operations analysis was conducted for the A.M. and P.M. peak hours at key <br />intersections to determine how traffic currently operates in the vicinity of the AUAR study <br />area. Refer to Table 7 for key signalized intersections analyzed and Table 8 for key <br />unsignalized intersections analyzed. Figure 14 shows existing geometries and A.M. and . <br />P.M. peak hour traffic volumes at these intersections. <br /> <br />Results of the operations analysis indicate that with the existing traffic controls and <br />intersections geometries, there are several intersections within the project area that <br />currently operate at LOS D or worse during the A.M. and P.M. peak hours (see <br />Tables 7 and 8). Table 7 shows that the signalized intersections of Lexington <br />Avenue/Eastbound 1-694 and Lexington Avenue/CR 96 operate at a LOS E in the P.M. <br />peak hour. The other three signalized intersections operate a LOS D or better, <br />Table 8 shows that five of the unsignalized intersections currently experience LOS E or F. <br /> <br />TABLE 7 <br />EXISTING A.M.
