The article is devoted to the issues of the transportation demand estimation. Existing methods to bring up to date the Origin-Destination matrix are reviewed. A regression method to update the passenger Origin-Destination matrix is proposed. The proposed method is compared with the method of calculating the Origin-Destination matrix using the population mobility data. The comparability of the proposed method with the standard method of calculating the Origin-Destination matrix is established. The characteristics of the transport mobility of Irkutsk city population are also established. The relevance of the research topic is determined by the growth of the level of vehicleto-population ratio and transport mobility of our country population that complicates the process of designing and managing urban passenger transport systems (UPT). One of the urgent objectives is the development of efficient methods to estimate the demand for transportation services, including ones to determine the distribution of this demand between UPT and individual road transport. Constantly updated information on transportation demand improves the efficiency of the management of the UPT system and improves the quality of transportation services provided to the population.

“…Поэтому не всегда представляется возможным скорректировать длительность светофорного цикла. Кроме того, кардинальный пересмотр цикла не всегда целесообразен, т. к. транспортные потоки, движущиеся в поворотных направлениях движения, как правило, составляют не более 20-30% от суммарного числа ТС [3,8,10,14]. В связи с этим, количество подъезжающих ТС в течение светофорного цикла регулирования будет больше, чем вместимость ПНП.…”

Abstract. Currently, in the course of measures to organize traffic in cities, the method of canalization of left- and right-turn traffic flows is widely used. This method consists in the construction of additional left- and right-turn storage lanes on the road network, especially at regulated intersections. However, in modern domestic and foreign scientific and regulatory literature, there are no clear scientifically based recommendations on the use of the method of canalization of traffic flows. The purpose of this work is to improve the efficiency of traffic management by channeling traffic flows in turning directions at urban regulated intersections. The scientific novelty of the study lies in the development of theoretical provisions on the formation of traffic queues that determine the capacity of transition-accumulation lanes used at urban regulated intersections for canalization of left-turn traffic flows. The authors also proposed a simulation mathematical model that displays the combined effect of the work of the controlled intersection and the load factor in the considered direction of movement. To obtain the initial load factor data, the Box-Muller transformation modeling method was used, as a result of which the required range of load factor values was obtained for different standard deviations. The result of processing the experimental data showed that the process of changing the length of the turning lanes under the influence of traffic lights and the load factor is described by a linear model. The developed model will make it possible to adjust the duration of traffic light control depending on the capacity of the turning lanes in such a way as to ensure the presence of all vehicles that accumulate over the total duration of the traffic light cycle and are waiting for traffic, as well as to make calculations at the stage of creating traffic management projects (hereinafter referred to as RTD). The results obtained also made it possible to determine the prospects and directions for further research: 1) conducting a full-scale experiment to confirm the results of the study. Confirmation of the hypothesis about the subordination of the load factor to the normal law of the distribution of a random variable; 2) the study of other factors that affect the capacity of headlands: the intensity of the oncoming flow of vehicles, the geometric dimensions of the intersection, weather conditions, etc.
