Debra Bloom,, P.E. <br />City of Roseville <br />Year 2030 , Peak Hour Intersection Operations <br />July 13, 2011 <br />Page 19 <br />To determine how the existing and potential (with the County Road C2 connection) roadway <br />network will operate under year 2030 conditions, a p.m. peak hour intersection capacity analysis <br />was completed. This analysis was used to compare the operational impacts with or without the <br />potential County Road C2 connection. <br />The year 2030 operations analysis results shown in Table 4 indicate that all key intersections will <br />operate at an acceptable overall LOS A during the p.m. peak hour with existing traffic control <br />and geometric layout. All side-street delays are considered acceptable and do not require <br />mitigation. Under year 2030 conditions with the County Road C2 connection, all key <br />intersections will operate at an acceptable overall LOS C or better during the p.m. peak hour with <br />existing traffic control and geometric layout. The side-street at the Lexington Avenue North and <br />County Road C2 intersection will operate at LOS F with an eastbound side-street delay of <br />approximately two minutes. Side-street delays of this magnitude are generally considered <br />unacceptable to motorists and warrant mitigation. <br />Table 4 <br />Year 2 Peak ,030 Pe Hour Capacity Anal�ys,iis, Comparison <br />Legal LeveI of Service Res,ul�ts, <br />Intersection <br />P.M.

The overall LOS is shown <br />followed by the worst approach LOS. <br />Parentheses indicate the intersection operations with the recommended improvements. <br />To improve the side-street delays at the Lexington Avenue North and County Road C2 <br />intersection under year 2030 conditions with the County Road C2 connection),, an eastbound <br />right-turn lane should be constructed. With the recommended right-turn lane, the Lexington <br />Avenue North and County Road C2 intersection will operate at LOS BAF (shown in parentheses <br />is Table 4 . Side-street delays along County Road C2 will be approximately 90 seconds. While <br />this may be perceived unacceptable, it will only occur during the peak hour, which represents a <br />small proportion of the overall daily operation. However, if the side-street delays are considered <br />unacceptable by the City, installation of a traffic signal would mitigate this condition. Based on <br />a preliminary review of the p.m. peak hour traffic volumes, the Lexington Avenue North and <br />County Road C2 intersection will likely meet the peak hour traffic signal warrant. <br />
