99This system was inst<strong>al</strong>led on Dixie Highway from August 12, 2004 until October 20, 2004.During this time, sever<strong>al</strong> near acc<strong>iden</strong>ts were recorded, but no actu<strong>al</strong> acc<strong>iden</strong>ts. Please review theacc<strong>iden</strong>t recording system videos included with this report. Sever<strong>al</strong> of the near acc<strong>iden</strong>ts werethe result of the commerci<strong>al</strong> driveways <strong>al</strong>ong the corridor. Vehicles entering and exiting thesedriveways produced sever<strong>al</strong> of the near acc<strong>iden</strong>ts recordings.Bustetter/Goodridge & Turfway RoadThe most prev<strong>al</strong>ent acc<strong>iden</strong>t type on this segment of roadway was angle acc<strong>iden</strong>ts, representing48% of the acc<strong>iden</strong>ts at this location. Similar to the previous section, this section of roadway hassever<strong>al</strong> curb cuts and business driveways. Vehicles turning into and out of the businesses poseunexpected obstacles to through traffic, resulting in the high number of angle acc<strong>iden</strong>ts.Solutions for these driveways are covered in more detail in the Long Term RecommendationsSection (Section 15) of this report, as well as Appendix A: <strong>Ac</strong>cess Management.Rear-end acc<strong>iden</strong>ts account for 27% of the acc<strong>iden</strong>ts on this segment of roadway. Sever<strong>al</strong> of thedrivers on Dixie Highway will slow or stop to <strong>al</strong>low a vehicle to exit driveways. Often, thefollowing drivers do not expect to be confronted with these sudden stops, and thus they result inrear-end acc<strong>iden</strong>ts.Left turning acc<strong>iden</strong>ts account for 14% of the acc<strong>iden</strong>ts on this segment of roadway. This type ofacc<strong>iden</strong>t is most likely caused as vehicles make left turns into or out of the commerci<strong>al</strong>driveways.For this section of roadway, most acc<strong>iden</strong>ts are caused by the large number of commerci<strong>al</strong>driveways located on Dixie Highway. Recommendations to remedy this problem are presented inthe Long Term Recommendations Section (Section 15) of this report, as well as Appendix A:<strong>Ac</strong>cess Management.Dudley/Summit & Edgewood RoadThe most prev<strong>al</strong>ent acc<strong>iden</strong>t type on this segment of roadway was rear-end acc<strong>iden</strong>ts,representing 70% of the acc<strong>iden</strong>ts at this location. The majority of the rear-end acc<strong>iden</strong>ts on thissegment occur on the northbound approach. This segment of roadway experiences a great de<strong>al</strong> ofcongestion, especi<strong>al</strong>ly in the northbound right lane. At the intersection of Dixie Highway andSummit/Dudley sever<strong>al</strong> vehicles turn right causing congestion in the right turn lane. DudleyRoad is used to access Turkeyfoot Road. A right turn lane would greatly improve the operationof this intersection.This improvement will be discussed further in the Long Term Recommendations Section(Section 15) of this report.<strong>An</strong>gle acc<strong>iden</strong>ts accounted for 19% of the acc<strong>iden</strong>ts on this segment. A review of the clearanceinterv<strong>al</strong>s of each intersection based on the information provided by KYTC was conducted. Basedon this review, the clearance interv<strong>al</strong> for this intersection appears to be slightly shorter thannecessary. This causes some drivers to decide to stop and could lead to rear-end acc<strong>iden</strong>ts, andsome drivers to proceed through the intersection, resulting in angle acc<strong>iden</strong>ts. !" .
