Future Year Traffic Operations Analysis Turning movements were estimated for the year 2040 No Improvement and Baseline scenarios. The future year turning movements were estimated using the existing turning movements and adjustments were applied based on future traffic growth and travel pattern shifts predicted for each scenario. These future year turning movements were evaluated in the traffic operations model to evaluate the performance of each scenario. The results of the future year traffic operations analysis are reported as level of service (LOS) and include estimated delay at each approach. Year 2040 No Improvement Scenario The Year 2040 No Improvement Scenario includes the year 2040 SE data assumptions and the existing year 2018 roadway network. To determine how the CSAH 5 corridor will accommodate the Year 2040 No Improvement 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 7. Table 7: Year 2040 No Improvement Scenario Operations Analysis AM Peak PM Peak LOS Delay (sec.) LOS Delay (sec.)

Delay shown is that of the worst performing approach. Intersecting Roadway Results of the Year 2040 No Improvement scenario capacity analysis indicate that all study intersections currently operate at an overall acceptable overall LOS C or better during the weekday peak hours. The westbound approach at the CSAH 62 (Green Valley Road) intersection operates at a LOS F with a delay of 71 seconds. 15
