The method and results of transport research, carried out by field research method, on the determination of the main indicators of traffic flows with significant unevenness of the movement on the arterial street in conditions of coordinated control is reviewed in the paper. Time parameters of traffic light control for which a reduction in traffic delay is achieved in direct and opposite traffic flow by the change of permissive signal depending on traffic intensity are determined using the simulation method. Change (increase) of the duration of the permissive signal provides uninterrupted movement of vehicles` group during their passage of stop-line at traffic light objects. The proposed method can be used on sections of transport networks with coordinated control, where there is significant heterogeneity of traffic flow, and it prevents the dissipation of groups that consist of vehicles with different dynamic characteristics. Such a result is being performed in the case when in the system of automated control, which combines adjacent intersections on an arterial street, fixed-time program control of traffic light signalization is operating. In this condition, there is a possibility to adjust the duration of signals of traffic light groups by correcting the width (permissive signal duration) and angle of inclination (speed of movement) of the timeline in coordination graphs. The scientific novelty of this research is that the method of traffic delay minimization in conditions of coordinated control acquired further development. The essence of the method is in the controlled change of the range of permissive signal duration in conditions of simultaneous control of the speed of movement between adjacent intersections. Practical value is the application of different programs of traffic light control on sections of arterial streets in transport districts where a significant difference of values of traffic intensity by directions is in morning and evening peak periods.

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.
