Mr. Rob Carnachan Page 8 March 6, 2025 <br />operating at the same Levels of Service in both directions as without project-related traffic. A summary of the <br />roadway segment level of service calculations is presented in Table 8 and copies of the calculations are enclosed. <br />Table 8 – Existing and Existing plus Project Peak Hour Roadway Segment Levels of Service <br />Study Segment <br />Direction <br />Existing Conditions Existing plus Project <br />AM Peak PM Peak AM Peak PM Peak <br />FD LOS FD LOS FD LOS FD LOS <br />1.

This is an <br />iterative process that employs existing turn movement data, existing link volumes and future link volumes to <br />project likely turning future movement volumes at intersections. <br />Under the anticipated future volumes, and with no changes to existing geometrics or controls, all of the study <br />intersections are expected to continue operating acceptably during both peak hours. Upon the addition of <br />project-generated traffic to the anticipated future volumes, the study intersections would continue operating <br />acceptably. Operating conditions are summarized in Table 9.
