City of Roseville i YEAR 2030 CONDITIONS � 3 � � � r S � l� ]1 � �, 1? l� 1� l� l� l8 E� �� �� � �� �3 ��i July 18,2007 Page 6 In order to determine how this area will operate under future conditions, year 2030 peak hour traffic volumes were developed for the key intersections along Fairvievv Avenue. Year 2030 volumes were developed using data from the recently completed Twin Lakes AUAR Update. Based on development assumptions contained therein, an annual growth rate of one-half percent was applied to the existing peak hour turning movement volumes to develop year 2030 background traffic forecasts. Adjacent land uses expected to deve�op/redevelap were then added to produce the year 2030 forecast volumes. Figure 3 displays the resultant year 2030 forecast traffic volumes. An operations analysis was conducted for the weekday a.m., midday, and p.m. peak hours as well as the Saturday midday peak hour at the key intersections along Fairview Avenue to determine how the proposed Alternatives will operate under year 2030 conditions. Analysis results shown in Table 3 indicate that under year 2030 peak hour conditions, all key intersections will continue to operate at an acceptable overall LOS A, with existing traffic controls and geometric layout. However, it is worth noting that during the weekday midday and p.m. peak hours, the west approach of 4akcresi Avenue is expected to operate at LOS E(approximately 40 seconds of delay). It should also be noted that as side-street delays increase, safety begins to degrade. As delays increase drivers will begin to accept smaller gaps in order to enter the traffic stream and make their ttxrning maneuver.
