This Circular on driveway and street intersection spacing has been developed in response to the need for information that may be applied in the development of sound spacing practices. It is a compilation of the contemporary practice that illustrates the basic considerations for spacing standards and guidelines and that describes current state, county, and local spacing requirements. The Circular begins with an overview on access management and a look at access management benefits. Section 2 presents general considerations in establishing spacing and the number of driveways; section 3 identifies the various technical considerations associated with setting spacing requirements for signalized intersections, corner clearance, and unsignalized intersections; section 4 contains regulations, policies, and standards for state highway systems; section 5 presents regulations, policies, and standards for local highway systems; and section 6 sets forth the conclusions.
