LaLonde Development Traffic Study May 1, 2024 Page 2 EXISTING CONDITIONS Existing conditions were reviewed within the study area to establish current traffic conditions to help determine impacts associated with the proposed development. The evaluation of existing conditions included collecting traffic volumes, observing transportation characteristics, reviewing crash history, and analyzing intersection capacity, which are described in the following sections. Traffic Volumes Vehicular intersection turning movement counts were collected at the following locations on Thursday April 4, 2024. A 13-hour count (i.e., 6 a.m. to 7 p.m.) was collected at Centerville Road (CR 21), while the count at Progress Road was collected from 7:30 to 9:30 a.m. and 3:00 to 5:00 p.m. Note that Centerville Elementary School hours of operation are generally from 9:15 a.m. to 3:45 p.m. Main Street (CR 14) and Centerville Road (CR 21) Main Street (CR 14) and Progress Road / East School Access The a.m. and p.m. peak hours within the study area represent 8:30 to 9:30 a.m. and 3:30 to 4:30 p.m., which generally coincides with the adjacent Centerville Elementary School. Average daily traffic (ADT) volumes were provided by MnDOT or estimated based on the data collected. Transportation Characteristics Observations were conducted within the study area to identify various transportation characteristics such as roadway geometry, traffic controls, speed limits, and multimodal facilities. A general overview of key roadways within the study area is as follows: Main Street (CR 14) a 3-lane undivided minor arterial roadway with a center two-way left-turn lane or dedicated left-turn lanes, and periodic right turn lanes. On-street parking is allowed in segments. A multiuse trail is along the south side of the roadway and on the north side from 150 west of Centerville Road (CR 21) to 150 east of Progress Road; a sidewalk continues along the north side east of Progress Road. The speed limit is 30-mph east of Centerville Road and 35-mph to the west. Centerville Road (CR 21) a 2-lane undivided minor arterial roadway with periodic turn lanes south of Main Street (CR 14) and a 2-lane local roadway to the north. A multiuse trail is along the east side of the roadway, except between Main Street (CR 14) and Heritage Street, which has sidewalk; there is also sidewalk along the west side from Main Street (CR 14) to Sorel Street. The speed limit is 30-mph in the study area. Progress Road a 2-lane local roadway with no turn lanes. No multimodal facilities are located along the roadway; the speed limit is 30-mph; the school segment has two northbound lanes. The Main Street (CR 14) and Centerville Road (CR 21) intersection has all-way stop control, while the Main Street (CR 14) and Progress Road intersection has side-street stop control. Existing geometrics, traffic controls, and volumes within the study area are in Figure 2. Crash History Five (5) years of crash history were reviewed from 2019 through 2023. A total of four (4) intersection related crashes occurred along Main Street (CR 14) over the analysis period in the study area; three (3) at Centerville Road (CR 21) and one (1) at Progress Road. All the crashes at Centerville Road (CR 21) were rear-ends. No fatal or serious injury crashes were reported at these intersections.
