NorthPoint Industrial Park – Lake Elmo, MN │Traffic Analysis January 2022 14 TABLE 9: LEVEL OF SERVICE GRADING CRITERIA Level of Service Description Average Control Delay (seconds/vehicle) Unsignalized Signalized A Minimal control delay; traffic operates at primarily free -flow conditions; unimpeded movement within traffic stream. 0 – 10 0 – 10 B Minor control delay at signalized intersections; traffic operates at a fairly unimpeded level with slightly restricted movement within traffic stream. > 10 – 15 > 10 – 20 C Moderate control delay; movement within traffic stream more restricted than at LOS B; formation of queues contributes to lower average travel speeds. > 15 – 25 > 20 – 35 D Considerable control delay that may be substantially increased by small increases in flow; average travel speeds continue to decrease. > 25 – 35 > 35 – 55 E High control delay; average travel speed no more than 33 percent of free flow speed. > 35 – 50 > 55 – 80 F Extremely high control delay; extensive queuing and high volumes create exceedingly restricted traffic flow. > 50 > 80 For the purposes of this study, the worst individual movement delay was reported as the overall intersection delay at side street stop control intersections. 5.3 EXISTING YEAR (2021) I NTERSECTION A NALYSIS The Existing Year (2021) Condition analysis was completed to develop an understanding of the baseline operating conditions for the study area. The traffic volumes shown in Exhibit 3 were used in the Existing Year (2021) analysis. As previously discussed, these volumes were developed based on turning movement counts recorded in August 2021. Tables 10 – 11 provide a summary of the average delay (seconds per vehicle) and LOS under Existing Year (2021) Conditions for each movement at the study intersections during the AM peak hour and PM peak hour, respectiv ely. The full SimTraffic reports are included in Appendix E.
