Tart Lake <br />Road intersects Otter Lake Road on the west end and Elmcrest Avenue on the east end, <br />approximately 0.6 miles in length. The posted speed limit on Tart Lake Road is 30 mph. See Figure <br />1 for the study area. The data was collected using road tubes and the 85th percentile speed was <br />calculated using this data set. <br /> <br />Two previous speed studies were performed on Tart Lake Road, one in 2013 to determine to <br />potential issues of speeding and vehicles using the corridor as a cut -through route. Vehicle speeds <br />in one mph increments and daily volumes were collected as part of the studies. Although the results <br />of the 2013 study did not identify a significant speeding issue, a Driver Feedback Sign (DFB) was <br />installed for eastbound traffic east of Otter Lake Road where the 85th percentile speeds were 34 <br />mph. The second study in 2015 showed an 85th percentile speed of 31 mph east of Otter Lake <br />Road, indicating the DFB sign successfully reduced speeds. <br /> <br /> Figure 1.
