Adaptation Capacity of the Traffic Lights Control System (TSCS) as to Changing Parameters of Traffic Flows Within Intellectual Transport Systems (ITS)

The paper states the problem of assessment of adaptation capacity of the TLCS as to changing parameters of traffic flows. The object of the study is movement of vehicles on signal-controlled intersections. The subject of the study is the method of assessment of impact of basic parameters of traffic flows on the capacity of signal-controlled intersections. Analysis of effectiveness of existing approaches to calculation of the traffic lights control cycle time allows development of a mathematical model for justification of algorithms for traffic lights control, taking into account widely varying characteristics of traffic flows. A mechanism of implementation of the proposed control method into the ITS environment was developed on the basis of this model. A model experiment was carried out; assessment of end-to-end performance of the proposed mechanism was conducted.
