31 <br /> Draft 11-19-2013 <br /> High Frequency Crash Locations <br /> High frequency crash locations within the Study Area from 2007-2011 are depicted on <br /> the Eno EDD and Surrounding Area — High Frequency Crash Locations Map on page <br /> 19. The data was obtained from the North Carolina Department of Transportation <br /> (NCDOT) and is meant to provide a broad overview of existing accident rates for <br /> sections of roadway and intersections within the Study Area. <br /> Crashes have been grouped by number in the following five categories, identified on the <br /> map in different colors: <br /> 1 . 4-9 <br /> 2. 10-19 <br /> 3. 20-29 <br /> 4. 40-49 <br /> 5. 50 and above <br /> The categories identify both intersections and sections of roadways. <br /> The highest number of crashes, 50 and above, were on the sections of 1-85 west and <br /> east of the US 70 interchange, dropping in number across the Durham County line to <br /> the east to between 40-49 crashes. <br /> A section of US 70, between University Station Road and Linden Road, had between <br /> 20-29 crashes, with these two intersections and the adjacent sections of US 70 having <br /> between 10-19 crashes. Pleasant Green Road north of US 70 and NC 751 south of US <br /> 70 also had between 20-29 crashes. <br /> Old NC 10 west of Mt. Herman Church Road, NC 751 across the county line to the east, <br /> and US 70 west of Ameshia Drive has between 4-9 crashes. <br /> The purpose of the North Carolina Highway Safety Improvement Program (HSIP) is to <br /> provide a continuous and systematic process that identifies, reviews and addresses <br /> specific traffic safety concerns, including crash data. The analysis of crash data is used <br /> to identify where, when, and why crashes are occurring, which can then lead to <br /> mitigation of the crash issues through a determination of potential access management <br /> countermeasures including the following: <br /> • Installation/adjustment of auxiliary lanes (left turn, right turn, etc.) <br /> • Installation or removal of a traffic signal <br /> • Adjustment of signal phasing, timing, and/or system <br /> • Installation or widening of shoulders <br /> • Installation of median islands, leftovers, etc. <br /> 191 Page <br />
