Validation and the general algorithm are presented for a conflict opportunity-based annual accident prediction software for both signalized and unsignalized intersections over a wide variety of volume, geometry, speed, signal timing and phasing, and other variables. Validation to numerous intersections indicates an average prediction accuracy of 90% compared to the historical annual reported accident average at any individual intersection.
