West Armstrong Area Traffic Analysis Date: November 17, 2022 Page: 2 For westbound traffic, the amount of traffic coming from the east and entering any of the sites on the north was reviewed: • For the first access west of Armstrong Boulevard, we estimated 400 employees, or 180 trips entering in the AM. The right turn lane was determined to not be needed as westbound traffic is relatively low (605 vehicles or less in the AM). • Since the first access did not need a right turn lane, accesses further west wouldn't need right turn lanes either. Left Turn Lane For Ferret Street, just west of the existing median, the left turn volumes are estimated to be low in the AM peak but much higher in the PM peak. The industrial traffic will come from both Hwy 10 and from the north and east. Approximately 50% of the traffic entering the area will gain access at 147' Avenue. The traffic to and from the ARAA recreational facility is projected to come from the residential areas of the City. This indicates that the amount of traffic from Bunker Lake Boulevard is likely to be higher, 55% at the Ferret Street and Bunker Lake Boulevard access: • 25% from Armstrong Boulevard north of Bunker Lake Boulevard, • 5% from the west on Bunker Lake Boulevard, and • 25% from Bunker Lake Boulevard east of Armstrong Boulevard. The remaining 45% of the traffic is projected to use 147th Avenue: • 5% from Hwy 10, • 5% from 147th east of Armstrong Boulevard, • 20% from Armstrong Boulevard north of Bunker Lake Boulevard, and • 15% from Bunker Lake Boulevard east of Armstrong Boulevard. A left turn lane was found to be warranted in the AM based on the following: • Roadway Speed = 40 mph, • Advancing Volume = 823, • Opposing Volume = 493, and • Left turn volume estimated to be 38. A left turn lane was found to be warranted in the PM based on the following: • Roadway Speed = 40 mph, • Advancing Volume 826, • Opposing Volume 754, and • Left turn volume estimated to be 205. Based on the above information, a westbound left is appropriate for the westbound Bunker Lake Boulevard traffic at Ferret Street. With the low speeds and an urban setting, but significantly higher left turn volume in the PM peak hour due to the recreational facility, a minimum length 210-foot, full -width left turn lane would be appropriate. Tapers can be at either 10:1 or 15:1. There could be need for the left turn lane to be longer based on other development changes that could occur along Ferret Street.
