Draft 09-09-2013 <br />18 | Page <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 prov ide 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 fo llowing 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 I-85 west and <br />east of the US 70 interchange, dropping in number across the Dur ham County line to <br />the east to between 40-49 crashes. <br />A section of US 70, between University St ation 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 no rth 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 Caro lina Highway Safety Improvem ent Program (HSIP) is to <br />provide a continuous and system atic process that identif ies, reviews and addresses <br />specific traffic safety concerns, including cras h 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 potent ial 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 />90
