<br />TRAFFIC ANALYSIS <br /> <br />Regional System Impacts <br /> <br />1-35W and TII 36, principal arterials serving the site, currently operate at capacity in the peak <br />hours and will continue to be congested as the region develops, regardless of redevelopment in <br />the Twin Lakes site. Redevelopment of the Twin Lakes area will increase peak-hour/peak- <br />direction demand on northbound 1-35W by 9 percent north of County Road D and increase <br />demand on eastbound 1H 36 by 7 percent east of Snelling Avenue. <br /> <br />Table 8 shows the estimated effects of the improvements on the nearby principal arterials. The <br />regional Transportation Development Guide includes improvements to both 1-35W and 1H 36, <br />but not until the post-2015 time period. The freeway system currently operates at Level of <br />Service E in the p.m. peak hours. In the year 2020, the freeway system will remain congested <br />regardless of the development scenario. However, with the additional capacity planned for 1H <br />36 and 1-35W the congestion will be no worse than current conditions under even the worst-case <br />condition. <br /> <br />Table 8 <br />Regional System ImpactslPeak Direction Segments <br /> <br /> Existing PM Existing <br /> Peak Hour Level of 2020 PM Peak 2020 Level of <br />Freeway Sel!ment Volume(!)
