The promotion paper consists of the introduction, five chapters, conclusions and list of the applied literature sources. The first chapter of the promotion paper analyses the existing systems of the city transport, clissifies the elements of the system and their interoperation; the mathematical model of the transport system is developed from the set theory point of view, the constant and variable elements are defined in the system, the detailed mathematical model of the research object – transport system element – crossing – is developed, the task of the schedule theory is stated and the target function is defined for the solution of this task in accordance with computer control of the electric transport movement by means of embedded device and schedule theory. The second chapter of the promotion paper contains the description of the developed algorithms for the calculation of each criterion as well as the total value of the target function. Therefore the application of the immune and genetic algorithms allowed developing the model of transport system control. The third chapter describes the developed embedded device, the electrical circuits of it and its components; the connection of the intelligent transport system to the elements of infrastructure, crossings, and city transport and railway transport units is analysed. The opportunities of the investigated algorithms application for the control of city transport are researched in the fourth chapter. A real existing transport system of Riga is investigated at the particular parts of the city; and for the approbation of the algorithm a simplified computer model of railway and auto transport movement at the particular crossing was developed with determined number of transport units and their schedule. The control of the transport system fragment is modeled in accordance with the developed algorithms realizing different sets of experiments. The fifth part of the promotional paper analyses and evaluates the results obtained in the previous chapter. According to the target function criteria the proposed changes of transport schedules of genetic and immune algorithms for each separate criterion as well as for the target function in general. The evaluation of the schedules changes was realized by means of the statistical evaluation method according to z-criterion, chi-square and Kolmogorov-Smirnov test. Thesis written in the Latvian language on page 155, contains an introduction, five chapters, conclusions, annex, 32 pictures, 70 tables. The bibliography contains references to 101 sources of information.
