24-30671 ASH STREET TRAFFIC IMPACT STUDY - LINO LAKES, MN Holly Drive N is a north -south roadway with a posted speed limit of 45 MPH. The typical roadway section is an asphalt two-lane undivided roadway with no shoulders, sidewalk or bicycle accommodations. TRAFFIC CONTROL The intersection of CSAH J/Ash Street and CSAH 21/Centerville Rd is all -way -stop controlled. CSAH 32/Ash Street is stop - controlled at its intersection with CSAH 21/Centerville Road, and a northbound left -turn bypass is provided. Monarch Way, Rapp Farm Blvd, and Holly Drive N are stop controlled at their intersections with CSAH 32/Ash Street. There are plans to reconstruct the CSAH 21/Centerville Rd's intersections with CSAH J/Ash Street and CSAH 32/Ash Street from stop -controlled intersections into roundabouts, and this is anticipated to be completed in 2025. The intersection of CSAH J/Ash Street and CSAH 21/Centervi Ile Rd (Intersection 1) will be a single lane roundabout with 10-foot shared use paths providing bicycle and pedestrian accommodations. The intersection of CSAH 32/Ash Street / CSAH 21/Centerville Rd (Intersection 2) will be a single lane roundabout with 8-foot and 10-foot shared use paths providing bicycle and pedestrian accommodations. Exhibits showing the existing and planned traffic control are provided in Appendix E. VEHICLE CLASSIFICATION Trucks are expected to use CSAH J/Ash Street and CSAH 32/Ash Street to access the study area, then use the development driveways to reach the commercial area. Pedestrians and bicyclists, mainly residents in the proposed developments, are anticipated to use any available pedestrian and bicycle accommodations. Existing Traffic Volumes and Analysis Assumptions Traffic count data was collected through video at Intersections 1 through 5 on Thursday July 18th, 2024 from 6:OOAM - 9:OOAM, and from 3:30PM - 6:30PM. The actual High and Low temperatures for the collection day were 55 ° and 81°. All roadways were clear and dry. The morning (AM) peak hour of traffic for the study area occurred from 7:30 AM to 8:30 AM. The evening (PM) peak hour of traffic for the study area occurred from 4:15 PM to 5:15 PM. About 60% higher traffic volumes were observed during the weekday PM peak hour than the AM peak hour within the study boundary. Some cyclists and no pedestrians were recorded during the peak hours of traffic. Summary diagrams of the network's peak hour vehicular traffic counts are provided in Appendix F. Using Synchro version 11.1, multiple delay computation methods are available, including the Percentile Delay Method, the Highway Capacity Manual 61h Edition methodology, Highway Capacity Manual 2010 Edition methodology, and Highway Capacity Manual 2000 Edition methodology. To analyze the traffic conditions within the study area for this report, Synchro version 11.1's Highway Capacity Manual 6th Edition delay method was utilized for all intersections. Intersections 1 - 5 were modeled. The resulting Synchro analysis worksheets were prepared for the existing conditions and are provided in Appendix G. Tables 1 - 5 show the existing level of service (LOS) and delay for Intersections 1 - 5 for both peak hour periods. In the existing condition, the southbound approach of Intersection 1 operate at a level of service F in both the AM and PM peak hours and all other movements operate at level of service D or better during the AM and PM peak hours. 0 Architecture + Engineering + Environmental + Planning Page 3 of 57
