The task of enhancing efficiency of traffic lights operation demands optimization of the throughput capacity of a regulated street and road network junction including rational and full use of an operation cycle of traffic lights. Oftentimes, the existing calculation system for an operation cycle of traffic lights at intersections does not provide a jam-free and safe route for transport in rush hours. In this article the authors suggest a new calculation methodology for an operation cycle of traffic lights based on the expert calculation which considers the necessity for keeping the possibility of entering a crossing by all vehicles that have arrived to a crossing from each of conflicting directions (including the most loaded one) during one cycle; the use of vehicles slow-down rate called in the traffic rules as “without emergency braking”; the use of phase coefficients at the calculation of the main cycles of the less loaded directions.
