Marc Culver, PE City of Roseville February 12, 2015 Page 24 • Results of the existing operations analysis indicate that all study intersections currently operate at an acceptable overall LOS D or better during the p.m. peak hour with the existing geometric layout and traffic control, except along County Road C at the Lincoln Drive and Snelling Avenue intersections, which operate at LOS F. o To mitigate this situation, modifications are necessary to the at grade intersections along Snelling Avenue or additional capacity is needed along the Snelling Avenue corridor. • SRF worked with City staff to develop a year 2030 land use plan in the study area. Trip generation estimates for both the current and future land uses were developed for the p.m. peak hour and on a daily basis using the HE Tri Generation Manual, 9tb Edition. o Assuming that the existing land uses generate at the average ITE trip rate, an additional 2,965 p.m. peak hour and 31,707 daily trips will be generated in the Twin Lakes Study Area under year 2030 full build conditions. • The Metropolitan Council regional travel demand model was used to develop average daily traffic (ADT) volumes for the greater adjacent roadway network, directional distribution for the p.m. peak hour trip generation estimates, and to estimate the potential for a subregional travel pattern shift with the extension of Twin Lakes Parkway to Fairview Avenue (i.e. non - Twin Lakes area development trips diverting to Twin Lakes Parkway). • Results of the year 2030 analysis indicate that there will be operational issues during the p.m. peak hour for all three scenarios under year 2030 conditions. • To improve operations, the following improvements should be considered. o County Road D and Fairview Avenue/New Brighton Road (all Scenarios) • Traffic control modification is recommended at this intersection. Further review is needed to determine proper traffic control, such as installation of a traffic signal or roundabout. • Construct or clearly delineate a northbound through/right turn lane. o Cleveland Avenue and County Road C2 • This intersection should be monitored as development occurs to ensure proper traffic control is installed. o Fairview Avenue and Lydia Avenue • This intersection should be monitored under future conditions. If operational issues occur consider installation of a traffic signal or roundabout. o Snelling Avenue • Modifications are necessary to the at -grade intersections along Snelling Avenue or additional capacity is needed along the Snelling Avenue corridor to mitigate the capacity issues that are observed. If this does not occur it is anticipated that traffic will divert to other routes, including regionally, subregionally, and locally.
