The goal of this paper is a development of system for appraising and comparing visibility risk factors of railroad grade crossings. Because accidents at crossings are related to diversity of driver behaviors, car approach speed and driver perception-reaction time, main factors of car braking distance evaluation, are assumed to be stochastically distributed. In this base, a concept of visibility risk at railroad grade crossings is established. Algorithm developed for evaluating visibility risk combines and includes these factors. Like this, visibility risk assessment system, based on database of properties of grade crossings and approach roads without accident records, is developed. With this system, improvement methods of the grade crossings with geometric risk factors can be presented.
