Taking into account the importance of time spent on passing distances of vehicle routes that lie across city road network (RN), well-known approaches to the determination of vehicle delay in the movement process (waiting for passage and the passage) of controlled intersections are analyzed. Reasons that cause the growth of these delays and that have an impact on traffic light cycle duration are counted. At the same time, the authors justify the need for change in the existing term transport delay. It should be interpreted (concerning intersection passage) as a delay only in the case when the group of vehicles that have stopped before intersection could not pass this intersection during the permission signal and wait for the next such signal. If the vehicles in the first group could pass the intersection (possibly taking into account also waiting for the permission signal), then this is not a delay but the necessary component of the technological process of the route passage. From this point of view, an approach in the traffic delay determination method at controlled intersections is proposed taking into account the particular components of Webster`s formula and the volume-capacity ratio of RN that determine the motorization level of the city population. A comparison of the results of delay calculation, determined with the use of the proposed method and Webster’s formula, is carried out
