Abramova L. Theoretical bases of distributed traffic control systems formation in cities

The thesis is dedicated to the problem of traffic efficiency increasing solution with maintenance of city road network capacity by implementation of continuous and safe transport process on the basis of the systematic approach to development of traf-fic management theoretical bases. A conceptual approach to the formation of hybrid control systems with the distribution of control functions by hierarchy levels is pro-posed. The diamond-shaped structure and algorithms of parametric and situational control in the conditions of parameters uncertainty and multicriteria of the control object are synthesized. A strategy for management systems designing is developed, based on the formalization of management methods for strategic, tactical, local and decision-making levels, taking into account the relationship of transport flow models at management levels and quantifying management effectiveness. Model experiments are performed to obtain the parameters of contour and dynamic control at the road network in Kharkiv, Ukraine with the help of developed simulation models, the ade-quacy of which is confirmed.
