“…Thus, an important direction to improve the existing situation on SRN and, in particular, to reduce traffic delays at intersections is to increase traffic safety, increase capacity, ensure proper conditions for the movement of public transport and pedestrians, etc. [3]. However, it is obvious that it is very difficult to take into consideration all the factors at the same time, especially for cities with dense infrastructure.…”

“…It should be noted that the whole set of technical means and methods of traffic management should be a single system, which is aimed at improving the safety and ease of movement of all road users [3]. Thus, owing to the introduction of modern means of information technology in the field of traffic regulation and control, it is possible to increase the capacity of intersections, traffic safety, and reduce vehicle delays.…”

The object of this study is a regulated intersection of city streets. The main task being solved is the reduction of queue lengths on approaches to such intersections by organizational measures. As a result of the research, patterns of change in queue lengths in front of the stop line were revealed, taking into consideration the specialization of traffic lanes and the distribution of traffic flows by directions. It was established that with an increase in the share of left-turning vehicles in the lane by 15 % and above, there is an increase in the length of the queue before the intersection from 45 to 80 m. The results indicate that when choosing a traffic pattern at the intersection, it is necessary to take into consideration not only the intensity of the flow itself but also the proportion of vehicles performing certain maneuvers (in this work, turning left is considered). A feature of the results is that they are obtained using simulation tools. This research method has made it possible to derive the value of the length of the queue in front of the intersection, changing the load on the approach from 200 to 1000 vehicle/h and the share of left-turning vehicles from 5 to 15 %. In addition, using a simulation model, it was checked how the intersection functions under various traffic management schemes on it when the input parameters of traffic flows change. The research results are recommended to be used in the development of traffic management schemes at regulated intersections. When determining the permitted directions of movement in the lanes, it is necessary to take into consideration the patterns of change in the length of queues before the intersection since under certain circumstances they may exceed critical values.

“…Additional delays also occur for public transport rolling stock, the uninterrupted passage of which through the coordination system depends not only on its dynamic characteristics but also on the duration of the delay at stopping points. Such delays are determined by the intensity of public transport and indicators of the variability of passenger traffic at bus stops [8].…”

Research results, using which the method of minimization of public transport delay is improved at intersections with the system of coordinated motion control, are given in this paper. Such transport research was carried out with simultaneous application of field measurements of the study of traffic flow indicators and computer simulation in PTV VISSIM to check the level of efficiency of coordinated control and the reliability of the results. The essence of the method is that it reduces the delay in traffic per user of the transport system during his movement through a signalized section of the road network. The effectiveness of this method is achieved under condition of significant intensity of public transport, which is provided with spatial priority in the form of the allocated lane. Invariability of the number of lanes in the area where coordination takes place, and a high level of transit (above 70%) of straight traffic flows are compulsory indicators and parameters. The result is achieved with such phases in the direction of coordinated control, the share of the permissive signal in which is more than 45% of the cycle duration with a duration limit of 90-125 s. With such parameters, the starting delays of the general traffic flow at the stop-lines are minimized, and the maximum values of the saturation flow are achieved. In addition, a sufficient width of the time lane is established for the passage of signalized areas by public transport. There is still some delay in public transport in such a control system, but it is connected with delays at bus stops. The introduction of such systems of coordinated traffic control is recommended on the arterial streets of citywide importance of controlled motion with a distance between adjacent stop-lines of not more than 800 m. This restriction allows avoiding the dissipation of groups of vehicles.

“…This phenomenon causes a significant increase in the amount of time spent by commuters in traffic. To face that challenge and reduce the congestion of the road network both in theory and practice, several well-established solutions are available [1][2][3][4][5], and these are mainly: − Optimization of network parameters (building of new or the reconstruction of existing streets and roads; design of arterial directions; parking restrictions, etc. ); − Optimization of functional and transport zoning (reduction of the share of transit motion; changes of city services; development of new functional or transport zones, etc.…”

Public Transport Prioritization and Descriptive Criteria-Based Urban Sections Classification on Arterial Streets

et al. 2023

The present paper is aimed at improving minimization methods in traffic flows, particularly reducing the costs of civil transportation through sections of the transport network by giving priority to public transport in densely developed areas. In cities with a radial and radial–circular planning scheme of the road network, where arterial traffic flows converge in the central part, the challenge of street congestion with traffic often arises. As a result, delays of all types of vehicles increase, which causes excessive travel time for users of private and public transport. In this regard, it is proposed to divide the sections of the transport network into eight types based on their geometric parameters and traffic conditions. This differentiation of sections improves the existing methods for determining the spatial delay of traffic flows on sections of the transport network with different parameters. It was achieved by considering the duration of vehicles passing signalized intersections and pedestrian crosswalks and the sections of streets between them, while simultaneously recording the duration of public transport movement, as well as the time they spend at stopping points, using GPS receivers. The results of onsite monitoring and further computations revealed that there are particular urban sections with specific, different distances between adjacent stop lines that are critical for public transport operation. Furthermore, based on the delay criterion, there were three different passage modes proposed to improve the efficiency of the traffic.
