Debra Bloom, P.E. July 18,2007 City of Roseville Page 8 I Alternatives 2 and 3 are expected to operate at an acceptable overall LOS B or better under year � 2030 peak hour conditions, with the respective traffic controls and existing geometric layout. � Again, installing traffic signals at one or both of the balccrest Avenue approaches will provide � additional gaps for the immediate or adjacent side-street approaches to Fairvi�w Avenue, thus 5 increasing safety for these vehicles and improving their access. Under year 2030 peak hour 6 conditions the installation of a traffic signal or signals does have a significantpositive impact on � the operations of the side-street appraach{esj. It should be noted that there will be no significant � queuing issues along Fairview Avenue, related to the installation of traffic signals under '� Alternatives 2 and 3. ] f] ] 1 The overall corridor operations were reviewed as part of the year 2030 operations as well to I� determine the impact Alternatives 2 and 3 will have on corridor mobility (travel time 13 comparison). Results of the analysis shown in Table 4 indicate that Alternative 2 will increase 1�� travel times along Fairview Avenue an additional five seconds during the p.m. peak hour (worst 15 case peak period). Alternative 3 will increase travel times along Fairview Avenue an additional l� 25 seconds during the p.m. peak hour (worst case peak period). It should be noted that the l r baseline travel time under Altemative 1 conditions (existing traffic control) was modeled to be I R approximately 215 seconds during the year 2030 p.m. peak hour. l� �+� Table 4 �] Year 2030 Volume Peak Hour Corridor Analysis �?� Travel Time Comparison Travel Time Difference in Seconds Intersection Weekday Saturday A.M.

Results of this analysis show that under existing volume �� conditions, the intersection of �'air�vievv� Avenu�/Oakcr�st Avenue does not meet signal warrants. 3�? However, although the intersection does not currently meet signal warrants the results indicate �� that minimal growth in traffic volumes could result in multiple signal warrants being met. �� Therefore, this intersection should be monitored continuously to determine its quantitative traffic �3.� signal need in the near future. Under year 2030 volume conditions, the intersection of Fairview ;3� AvenuelOakcrest Avenue meets multiple signal warrants, justifying the installation of a traffic �� signal under future conditions (see Appendix for signal warrant analysis data and graphics).
