Traffic Impact Study 20 New Brighton Exchange Update 5. Conclusions and Recommendations The principal findings from this traffic study are: • The remaining development sites for the New Brighton Exchange are expected to generate approximately 3,200 new trips during an average weekday, 350 new trips during the a.m. peak hour and 380 new trips during the p.m. peak hour. • All study intersections currently operate acceptably in the a.m. and p.m. peak hours. • The signalized intersections of Old Highway 8/Highway 96 and Old Highway 8/10th Street are forecast to operate acceptably through the 2033 Build scenarios. • The westbound 95th percentile queue lengths in the 2033 Build p.m. peak hour at Old Highway 8/14th Street and Old Highway 8/Northwest Parkway are forecast to be longer than desired. • Old Highway 8 has daily volumes that would be able to be supported by a conversion to a three-lane road. • Significant 95th percentile queue lengths are forecast for the 2033 Build p.m. peak hour at the three stop-controlled study intersections when Old Highway 8 is converted to a three-lane road. The following recommendations are made based on the above findings: • Move sight distance obstructions at Old Highway 8/Northwest Parkway to allow for adequate sight distance for vehicles on the side street approaches without needing to pull into the crosswalks. • Stripe westbound 14th Street and Central Park Boulevard to operate with two westbound approach lanes at Old Highway 8. • Once the New Brighton Exchange is fully constructed, new counts be collected, and signal warrants be run for the stop-controlled study intersections to determine when a signal would be needed based on volumes. • Keep the current four-lane layout along Old Highway 8.
