Abstract. The road network is one of the key elements of the urban road transport complex. The increase in the level of automobilization of the population has significantly increased the importance of this element of the urban infrastructure, the requirements for the level of design and the degree of justification for engineering solutions have increased. Consequently, research aimed at finding the most effective solutions in this area is relevant, and its results are in demand. Solving problems in the organization of traffic flow requires the development of a sequence of actions to ensure the adoption of design solutions to ensure maximum throughput of the considered section of the road network with minimum investment.
The purpose of the study is to identify promising areas of development of the urban street-road network based on the use of simulation methods.
The paper presents the results of the literature review, concluded that, if there is a methodological basis and the necessary software, there is no sound algorithm for making design decisions.
The theoretical and methodological approach proposed by the authors implies a grouping of measures for the reconstruction of the road network, based on the amount of capital investment necessary for their implementation. To determine the optimal design option, the conditions for the transition to each subsequent level of design are determined.
A parameter is proposed that allows an assessment of the effectiveness of design decisions related to the change in traffic management schemes and the reconstruction of a section of the road network.
The list of software products has been determined, allowing to determine the parameters for the implementation of the proposed design solutions. The algorithm for the implementation of the proposed methodological approach has been developed.
An approbation of the proposed methodology in practice, in the course of carrying out design work to improve one of the sections of the road network in the city of Orenburg, was carried out. The use of the proposed methods made it possible to develop a number of alternative design solutions and to identify a solution that ensures the greatest efficiency of investments.
The obtained results allow us to make a conclusion about the relevance of the problems considered in the work, the adequacy of the developed methodology and the feasibility of its use in assessing the effectiveness of alternative design solutions in the field of designing traffic management schemes and designing sections of the road network.
Keywords: simulation modeling, capacity, traffic management, road network.
