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 />181 Page <br />25 <br />
