Monograph

This issue contains nine papers on the operational effects of geometrics and access management. Specific topics addressed in this issue include the following: access spacing; wrong-way crashes on divided highways; lane utilization models for diverging diamond interchanges; empirical speed behavior on horizontal ramp curves; minimal U-turn offsets for unsignalized superstreets; raising speed limits on rural highways; J-turns on rural high-speed expressways; diverging diamond interchanges on adjacent roadway facilities; and operating speed models for tangent segments on urban roads.
