4. Fifth Street Intersection Improvements From Dodge Avenue to Twin Lakes Road, 5t" Street has a dominant east -west movement. Despite this prevailing movement, traffic is stopped at the intersection with Dodge Avenue and with Line Avenue. By making changes to these two intersections, the dominant movement could be better recognized and the east -west flow would improve. Traffic control warrants for the two 5th Street intersections were examined using existing volumes. If warranted, a change to all -way stop control or traffic signal control may provide the necessary recognition of the east -west movement. However, the volumes were relatively far from satisfying the traffic signal or all -way stop control warrants and this change is not warranted. It is unlikely that the changes associated with the Line Avenue alternatives would increase volumes enough to satisfy any warrants either. Therefore, traffic signal control or all -way stop control is not justified at the 5t" Street intersections with Dodge Avenue and with Line Avenue under any alternative, including existing. Geometric and traffic control changes to 5th Street to Dodge Avenue (and vice versa) and 5t" Street to the north segment of Line Avenue (and vice versa) movements would create this major street without stop signs. The west leg of 5th Street at Dodge Avenue and the south leg of Line Avenue at 5t" Street would create a `T' under stop control at the new roads. With these new geometric changes in place, capacity analyses were run on the Dodge Avenue/5t" Street and Line Avenue/5t" Street intersections. It is important to note that for Alternative A, where Line Avenue ends before Twin Lakes Road, the northern leg of Line Avenue would tee into a new continuous connection between 5t" Street and the southern leg of Line Avenue. As before, the LOS calculations were done in accordance with the 2010 Highway Capacity Manual using VISTROTM software. A summary of the LOS results for the 5th Street improvement layouts for each peak hour is shown in Table 7. The complete LOS calculations, which include queue lengths and grades for all individual movements, are included in the Appendix. Table 7 — 5t" Street Alternatives Level of Service' 'The first letter is the Level of Service for the intersection. The second letter (in parentheses) is the Level of Service for the worst operating movement. As shown in Table 7, the two 5t" Street intersections are forecast to operate acceptably with the proposed changes with or without any alternative for Line Traffic Operations Study 10 Line Avenue in Elk River
