City of Roseville CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendationsare offered for consideration. July 18,2007 Page 9 �► 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 a�erage side-street delay reported was less than 20 seconds per vehicle. Under Alternative 2 and 3 conditions, all key intersections will continue to operate at an acceptable overall LOS A or better during each of the peak hour time periods, with the respective traffic controls and e�sting geometric layout. o 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 �'airvi�w Avenue via Oa�CCrest Avenue. The installation of a traffic signal at the Fairview AvenuelOal�crest Avenue (West) intersection will create more gaps for the east approach of Oakcrest Avenue and Rose Place, improving their access to �airview Avenue. By installing traffic signals at both the east and west approaches of Oalccrest Avenue, Alternative 3 creates a safer condition for accessing Fairviev,r Avenue, providing protected movements to all users of Oakcresi Avenue. Vehicles using Rose Place will continue to benefit due to gaps created by the signal at the west approach of Oakcr�st Avenue. o The traffic signal under Alternative 3 was modeled with split phase traffic control. Split phase traffic control indicates that two phases at the intersection, that could otherwise run simultaneously, are run individually. This either provides additional protection for a particular movement or reduces the vehicular conflicts. This traffic control method may result in longer queues andlor delays. Providing this type of traffic control will ensure that the driveway access points located east of Fazrvi��v Avenue will have the opportunity for safe and efficient ingress/egr�ss. o It should be noted that the installation of a traffic signal will increase the potential for rear-end collisions along Fairoiernr Avenue, and potentially result in an increase in right-angle collisions due to vehicles along Fairview Avenue not complying with the traffic signal. • The overall corridor operations were reviewed to determine t�e impact Alternatives 2 and 3 will ha�e on corridor mobility (tra�el time con�parison}. Analysis results indicate that Alternative 2 will increase travel times along �'airvi�w Avenue an additional five seconds during the p.m. peak hour (worst case peak period). Alternative 3 will increase travel times along Fai;rview Avenue an additional 20 seconds during the p.m. peak hour (worst case peak period). It should be noted that the baseline travel time under Alternative 1 conditions (existing traffic control) was modeled to be approximately 145 seconds during the p.m. peak hour.
