Ramsey Town Center Traffic Analysis • Industry Avenue —widen to five lane cross section west of Ramsey Boulevard to provide two through lanes in each direction and a left turn lane/center median The existing cross sections on Armstrong Boulevard north of the railroad, Sunwood Drive and Industry Avenue east of Ramsey, and Sunfish Lake Boulevard north of the railroad would be adequate to meet the future demand. Turn lanes and lane adjustments would be needed at the following intersections: • TH 10 at Armstrong Boulevard —add an eastbound and a westbound through lane on the intersection approaches; add an eastbound and a southbound left turn lane and a southbound right turn lane. • TH 10 at Ramsey Boulevard —add an eastbound and a westbound through lane on the intersection approaches; add an eastbound and a southbound left turn lane and a westbound right turn lane. A southbound through lane and a northbound left turn lane and northbound through/right lane would need to be added to serve the Rivenwick 3rd Subdivision traffic independent of the project traffic. • TH 10 at Sunfish Lake Boulevard —add an eastbound and a westbound through lane on the intersection approaches; convert the southbound approach from a through/left turn lane and a right turn lane to through/right turn lane and two left turn lanes (this adds one lane to the approach). • Industry Avenue at Ramsey Boulevard —add a southbound right turn lane; eastbound and northbound approaches would be widened by the above recommendations. • Sunwood Drive at Industry Avenue —modify the shared lanes on the northbound, eastbound and westbound approaches to provide left turn lanes and shared through/right turn lanes Lane modifications and additions are shown in Figure 9. The following stop -controlled intersections would need to be signalized: • Ramsey Boulevard at Industry Avenue • Armstrong Boulevard at Industry Avenue • Industry Avenue at Sunfish Lake Boulevard • Ramsey Boulevard at Sunwood Drive • Sunwood Drive at Industry Avenue • Sunwood Drive at Armstrong Boulevard • NS3 Street at Industry Avenue The left turn volumes from the EW1 parkway onto both Armstrong and Ramsey Boulevard cannot be accommodated at an acceptable LOS under stop control and require signalization to achieve acceptable operations. However, the close spacing between the intersections of the EW1 parkway and the intersections of Armstrong and Ramsey Boulevard with Industry Avenue limits the potential for the two parkway intersections to be signalized. Accordingly the parkway intersections should be channelized to provide right-in/right-out and left -in access (3/4 access). Left out from the parkway would be prohibited and would redistribute to the north -south streets and to Industry Avenue (these volumes have been included in the mitigated calculations for the other intersections). Project Streets The extension of Sunwood Drive would be the primary east -west connector street in the project site and is estimated to carry 10,000 to 13,000 vehicles per day (vpd) west of NS6 Street. Volumes on Sunwood west of Ramsey would be about 18,000 vpd as shown in Figure 10. West of NS6 Street, the volume on Sunwood Drive would be adequately handled by a two-lane cross section (one lane in each direction). However, left -turn lanes would be needed at cross streets. Between NS6 Street and Ramsey Boulevard, four lanes would be needed to accommodate the projected volumes. Two-way or all -way stop control at the intersections of Sunwood Drive internal to the site would provide LOS C or better conditions for the March 2003 Meyer. Mohaddes Associates. Inc. 17
