A conceptual approach to estimating the risk of rear-end collisions at a signalized intersection is presented. It is argued that the creation of a large option zone increases the range of the indecision zone, the direction implication of which is an increase in the risk of rear-end collisions. With the aid of field data collected for two warning intervals (3 and 6 sec) before the red light, a large option zone is shown to increase the variance underlying the stopping probability curve, and thus to determine a larger range for the indecision zone. Data from urban intersections support the basic argument that a long warning period causes a significant increase in the number of rear-end collisions.
