LOS is a quantitative measure used by traffic engineers to describe the operations of an <br />intersection or along a roadway segment. It ranges from A to F, with A being the best and F <br />being the worst level of operation. LOS A conditions are characterized by minimal vehicle <br />delay and free -flow conditions, while LOS F is characterized by long vehicle delay - usually <br />when demand exceeds available roadway capacity. Although LOS E is defined as at - <br />capacity, LOS D is generally the minimum acceptable level of operation at an intersection <br />in the Twin Cities metro area. <br />Table 5: 2040 Peak Hour Traffic Analysis Results <br />As previously mentioned, many improvements to the transportation network in the vicinity of <br />the AUAR study area have been completed. Both roundabout intersections (County Road H <br />& 1-35W SB Ramp and County Road H & 1-35W NB Ramp) are anticipated to operate at LOS <br />C or better during the AM and PM peak hours of all scenarios, based on the 50% <br />confidence results. The intersection of CSAH 96 & US Highway 10 SB Ramp is anticipated to <br />operate at LOS D or better during the AM and PM peak hours of all scenarios. <br />The intersection of Mounds View Boulevard & County Road H is anticipated to operate at <br />LOS E during the PM peak hour in the build scenarios. The intersection is anticipated to see <br />some congestion due to the added site traffic and the number of through movements <br />along Mounds View Boulevard. Queues are not anticipated to impact adjacent <br />intersections; therefore, it is recommended to monitor the intersection as development <br />occurs to see if traffic volumes, delays, and queues are realized. <br />At the intersection of CSAH 96 & Northern Heights/TCAAP South Access, the baseline build <br />geometry is anticipated to be sufficient from an operational standpoint, but it is anticipated <br />that there would be queueing issues for the southbound right turn movement in all build <br />scenarios. Because of this, it is proposed that the through lane should be striped as a shared <br />through/right turn lane to allow right turns from two lanes.8 Alternatively, a channelized right <br />turn lane could be a viable solution to this issue but would require a larger right-of-way. <br />8 This recommendation is consistent with the mitigation proposed in Ramsey County's 2024 Rice Creek <br />Commons Traffic Study. <br />TCAAP AUAR Update 13 <br />April 2024 <br />
