Year 2040 Baseline Scenario The year 2040 Baseline Scenario includes the year 2040 SE data and all programmed roadway network improvements. CSAH 5 is a 2-lane undivided section with 8-foot shoulders under this scenario. To determine how the CSAH 5 corridor will accommodate the Year 2040 Baseline Scenario forecasts,an intersection capacity analysis was completed using Synchro/SimTraffic software. Results of the Year 2040 No Improvement Scenario capacity analysis are shown in Table 8. Table 8:Year 2040 Baseline Scenario Operations Analysis AM Peak PM Peak Intersecting Roadway LOS Delay(sec.) LOS Delay(sec.) CSAH 64 (181st Ave)* A/A A/A CSAH 63 (Green Valley Rd)* A/C B/F 56 CSAH 63 (175th Ave)* A/A A/A 7 170th Ave A B 18 167th Ave* A/C A/D 33 Ramsey Blvd* A/A A/E 45 Sunfish Lake Blvd* A/A 5 A/B 12 Alpine Dr* B 17 C 21 Sunwood Dr* A/B 10 A/A 7 Dysprosium St* A/A 6 A/A 7 TH 47 B 15 C 27 *Side stop-controlled intersections show overall intersection LOS followed by the LOS of the worst of the worst performing approach. Delay shown is that of the worst performing approach. Results of the Year 2040 Baseline scenario capacity analysis indicate that all study intersections currently operate at an overall acceptable overall LOS C or better during the weekday peak hours. Both the CSAH 63 (Green Valley Road) and Ramsey Boulevard intersections have approaches which operate below LOS C. Additionally, the results of the Year 2040 Baseline scenario capacity forecasts showed that the improvements to US Highway 10 are expected to shift traffic from TH 47 to CSAH 56 (Ramsey Boulevard) and CSAH 57 (Sunfish Lake Boulevard). The operations results shown here demonstrate that the CSAH 56 northbound approach to CSAH 5 deteriorates to a poor level of service when accounting for the traffic shift anticipated from the improvement to US Highway 10. 16
