Abstract

The relationship is examined between accident rate and curvature on loop and outer connection ramps. Ramp characteristics considered include maximum curvature location of ramp, enter or exit direction, with respect to the main-line unit an average daily traffic. Results indicate that accident rates increase with maximum curvature for all right entering or exiting loops and outer connections except rural loops.
