Marc Culver, PE <br />City of Roseville <br />Intersection Operations Analysis <br />February 12, 2015 <br />Page 17 <br />To determine if the roadway network can accommodate the year 2030 traffic forecasts, a detailed <br />intersection capacity analysis was completed. The study intersections were analyzed using <br />Synchro/SimTraffic software and the HCM. The intersection improvements identified at County <br />Road C/Snelling Avenue under existing conditions (i.e. six -lane along Snelling Avenue) are included <br />in the year 2030 analysis; as are the improvements identified at the NB I -35W Ramps/Twin Lakes <br />Parkway intersection. Results of the year 2030 analysis shown in Table 7 indicate that there will be <br />operational issues during the p.m. peak hour for all three scenarios under year 2030 conditions. <br />Table 7.
