This <br />intersection currently operates at an undesirable LOS F. It is important to note that existing <br />signal timing obtained from Mn/DOT and Ramsey County was used in the analysis. <br /> <br />Table 2 <br />Existing Year 2006 P.M.

Overall LOS is shown followed by worst approach LOS. <br />** Indicates an intersection with all-way stop control. <br />(1) Value shown in parenthesis represents the average delay per vehicle. <br /> <br />In order to improve the County Road C/Snelling Avenue existing intersection operations to <br />LOS 0, the following geometric improvements are recommended: construct an additional north <br />and southbound through lane along Snelling Avenue; and construct an additional left-turn lane at <br />the eastbound and westbound approaches (dual left-turn lanes). <br />
