<br /> <br /> <br /> <br /> <br /> <br />Scenario 2 <br />Based on the analysis of future traffic volumes for Scenario 2 adding a third lane on <br />TH 10 / 169 could delay the need for an interchange by approximately six years. <br />TH 10 ,/ 169 Interchange - The fu11_ build condi*_ions were analyzed assuming a <br />standard diamond interchange at TH 10 / 169 and Twin Lakes Parkway with the <br />future roadway network shown in Figure 21-4, and assuming full build of the <br />development area. The results of the analysis indicate that with the standard <br />diamond interchange the amount of traffic turning at the interchange ramps is <br />extremely high and cannot be accommodated with this type of interchange. The <br />overall LOS at both ramp intersections is LOS C / B in the AM peak hour and LOS D / <br />F in the PM peak hour. Assuming an interchange with additional capacity such as a <br />single point or diverging diamond, the overall LOS could be improved to a LOS D / E, <br />with some movements still at LOS F. <br />Twin Lakes Parkway at 168 Avenue -This intersection would experience delays <br />for both the northbound and westbound approaches during AM and PM peak hours. <br />The overall LOS at this intersection is projected to be F during both the AM and PM <br />peak hours. If a roundabout or traffic signal is installed the operations would <br />improve to an LOS C. <br /> <br /> <br /> <br /> <br /> <br /> <br />fl <br /> <br /> <br /> <br />Twin Lakes Parkway at Wilson Street -This intersection is located on the south side <br />of TH 10 / 169. The delays at this intersection are strictly the result of the <br />interchange operation and would be eliminated with a higher capacity interchange. <br />All other study area intersections would be operating at LOS C or better during both <br />the AM and PM peak hours.
