SAFETY BENEFITS OF ACCESS SPACING

Herbert S. Levinson, Jerome Gluck

Open publisher page 7 citations

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 spac-ing 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 inter-secting roadways or driveways per mile. As early as 1953, research results showed that accident rates generally increased with both the frequency of access and the average daily traffic; however, the greatest increases resulted from increasing the number of access points per mile.
