Efland-Buckhorn-Mebane Access Management Plan <br /> ACCESS MANAGEMENT PROGRAM <br /> (To Be Applied Within Corridors And Development Zones) <br /> ACCESS MANAGEMENT CONCEPTS <br /> 1. Driveway-Related Crashes <br /> Much of access management involves managing traffic movements into and out <br /> of commercial driveways. The reason for this is that driveway traffic generates a <br /> large number of crashes on major roads and streets-arterials and collectors. <br /> 2. Driveway Spacing <br /> Maintaining an adequate spacing between commercial driveways is one of the <br /> most critical aspects of access management. <br /> 3. Driveway Density And Driveway Consolidation <br /> Driveway density (the number of driveways per block or per mile) and driveway <br /> consolidation are very important considerations in access management. These <br /> roadway characteristics are basic issues in any access management plan or <br /> program. <br /> 4. Intersection Spacing And Traffic Signal Spacing <br /> Although most discussions about access management focus on the <br /> management of private driveways, proper spacing of roadway intersections is an <br /> equally important access management issue. <br /> Why is intersection spacing important? <br /> The importance of intersection spacing is similar to that of driveway spacing. As <br /> the number of intersections per mile increase, the opportunity for crashes <br /> increases. The existence of too many intersections per mile also increases delay <br /> and congestion. On the other hand, not providing an adequately dense street <br /> network forces motorists and pedestrians to travel farther to their destinations. <br /> 5. Functional Areas Of Intersections <br /> It is important to protect the functional area of an intersection from driveway <br /> access. Driveways located within this area may result in higher crash rates and <br /> increased congestion. <br /> What is the functional area of an intersection? <br /> The functional area of an intersection is that area beyond the physical intersection <br /> of two roadways that comprises decision and maneuvering distance, plus any <br /> required vehicle storage length. The functional area includes the length of road <br /> upstream from an oncoming intersection needed by motorists to perceive the <br />
