• Abstract:
  The spacing of driveways and streets is an important element in roadway planning, design, and operation. Access points are the main source of accidents and congestion. Their location and spacing affects the safety and functional integrity of streets and highways. Too many closely-spaced street and driveway intersections increase accident potential and delays, while too few inhibit access and over-concentrate traffic. More than 40 years of research has indicated that accident rates increase with the number of intersecting roadways or driveways per mile. This paper describes the results of many research studies that identified the safety benefits of access spacing. These findings provide a basis for establishing sound access spacing practices. 6p.
