<br />ACCESS MANAGEMENT PROGRAM <br />(To Be Applied Within Corridors And Development Zones) <br /> <br />ACCESS MANAGEMENT CONCEPTS <br /> <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 /> <br /> <br />2. Driveway Spacing <br />Maintaining an adequate spacing between commercial driveways is one of the <br />most critical aspects of access management. <br /> <br /> <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 /> <br /> <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 /> <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 /> <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 /> <br />What is the functional area of an intersection? <br />The f unctional 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 /> 51
