Abstract

Guidelines for intersection sight distance are mostly outlined in general terms without showing effects of all the variables and assumptions involved. This paper provides theoretical analysis and sets guidelines based on the laws of motion for three types for intersection sight distances, namely (a) approach sight distance, (b) sign visibility sight distance, and (c) stop-line sight distance. The paper introduces guidelines for satisfying intersection sight distances for Stop sign, Yield sign and 'no traffic control' approaches in a systematic and in equation format that includes all the pertinent variables. The paper is especially useful for practitioners and policy makers.
