Joel Hanson September 23, 2013 Page 2 The following is a summary of the daily traffic volumes at these locations! « North and southbound Cherry Hill Lane south of Labors Road — approximately 275 vehicles per day. Westbound Labore Road east of Arcade Street - approximately 1,100 vehicles per day. tt Eastbound Labore Road east of Arcade Street — approximately 1,300 vehicles per day. Southbound Arcade Street north of Labore Road -- approximately 275 vehicles per clay, tt Northbound Arcade Street south of Labore Road •- approximately 780 vehicles per day. These traffic counts compare favorably to counts done in the past by the Ramsey County Shed Ws Office. 'Traffic Forecasts 'traffic forecasts were developed for the newly constructed Pinetree Court, Cherry Hill Lane with a connection to the east, and a new roadway to the east connecting to Labore Road north of Cherry Hill Lane. The forecasts were developed using the traffic count from Cherry Mill Lane, the number of households in the Cherry I-Iill Lane development, and the traffic volumes of surrounding streets. When the development is complete, Pinetree Court is estimated to have approximately 250 vehicles per day. A future connection of Cherry Hill Lane to the east will add an estimated 200 vehicles per day to Cherry Hill Lane south of Lahore Road, for a total of 475. The potential roadway to the east accessing Labore Road just north of Cherry Hill Lane will have an estimated volume of approximately 1,000 vehicles per day. 'these volumes are all in accord with recognized traffic volumes for residential streets. Cr ashes In addition to trafiie volume, intersection control warrant analysis also considers vehicle crashes. Vehicle crashes were reviewed at the intersection of Labore Road and Arcade Street and along Labore Road from Edgerton Street to County Road D. At the intersection of Lahore Road and Arcade Street there has been an average of L5 crashes per year for the last 3 years. This translates to a crash rate of 1.06 crashes per million entering vehicles. This rate is above the state average crash rate for a stop - controlled intersection of 0.30, but below the critical crash rate of 1.15. Therefore the intersection is considered safe due to the high probability (90 -95 %) that the higher than average crash rate is due to the random nature of crashes. Crashes were also reviewed along Labore Road from Edgerton Street to County Road 1D. This segment of Labore Road has a crash rate of 1.73 crashes per million vehicle miles. This rate is below the 230 state average crash rate for a two lane road. This also indicates a safe condition. Traffic Speeds Traffic speeds collected by the Ramsey County Sheriffs Office found that Labore Road has an average speed of 32 mph and an 85th percentile speed of 36 mph, which means that 85% of traffic is traveling at or below 36 mph. Sight Distance Our review of the area included measuring the available sight distance at the two intersections. Intersection sight distance allows drivers entering a roadway to be able to sea traffic on that roadway and therefore being able to determine if !hey can enter safely. Stopping sight distance allows drivers on a through roadway to be able to stop safely for an obstacle in their path. 3
