A multi-objective optimization problem for traffic flows in the urban road network is considered. A mathematical model of control object is given as a system of recurrent finite-difference equations. The control is a vector that determines the moments of switching the working phases of traffic lights at intersections. To solve the problem, it is proposed to use variational nondominated sorting genetic algorithm. Particular attention is paid to the presentation of possible solutions. The current signal timing for intersection is considered to be a basic solution. The search is performed on the space of variations of basic solution. An example of solving the multi-objective optimal control problem for sample X-type intersection is given.
