Debra Bloom, P.E. City of Roseville EXISTING CONDITIONS July 18,2007 Page 3 Current traffic controls include side-street stop control at each of the key intersections along Fairview Avenue. Peak hour turning movement counts were collected at each location by Ramsey County in June 2007. Existing geam�trics, traffic controls and peak hour traffic volumes for the key intersectionsare shown in Figure 2. r 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 9 how traffic currently operates and potentially will operate under the other two alternatives if E�1 improvements were implemented today. All intersections were analyzed using the I I �yncl�ro/SiamTraf�e and Highway Capacity Software. Capacity analysis results identify a Level 1� of Service (LOS), which indicates how well an intersection is operating. The LOS results are 13 based on average delay per vehicle, Intersections are given a ranking from LOS A through 1� LOS F. LOS A indicates the best traffic operation and LOS F indicates an intersection where �� demand exceeds capacity. LOS A through D is generally considered acceptable by drivers. I �k ] '� ]� ]� ��} �] �? �� �� For side-street stop controlled intersections, special emphasis is given to providing an estimate for the level of service of the minor approach. The traffic operations at an unsignalized intersection with side-street stop control can be described in two ways. First, consideration is given to the overall intersection level of service. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support those volumes. Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, the maj ority of delay is attributed to the side-street approaches. �� Results of the analysis shown in Table 1 indicate that all key intersections currently operate at an �� acceptable overall LOS A or better during each of the peak hour time periods, with existing �� traffic controls and geometric layout. The corresponding average side-street delay reported was 2S less than 20 seconds per vehicle. Although this delay is generally considered acceptable, �� residents may perceive this delay unacceptable and unsafe. Under Alternative 2 and 3 3+J conditions, all key intersections will continue to operate at an acceptable overall LOS A or better 3l during each of the peak hour time periods, with the respective traffic controls and existing �? � i �� 35 3�r �� �8 3� �0 �] �� geometric layout. Based on these operations results, the improvements do not appear to have a significant impact at the key intersections. However, the improvements do provide safe access for residents, businesses, and customers accessing Fairviern+� Avenue via Oalccrest Avenue. The installation of a traffic signal at the �'air�iew AvenuelOakerest Avenue (West) intersection will create more gaps for the east approach of �akcrest Avenue and Rose Place, improving their access to �'airview Avenue. By installing traffic signals at both the east and west approaches of Qakcr�st Avenue, Alternative 3 creates a safer condition for accessing Fairvievv Avenue, providing protected movements to all users of �akcxest Avenue. Vehicles using Rose Place will continue to benefit due to gaps created by the signal at the west approach of 4akcr�st Avenue.
