Abstract
Nowadays the main task remains analysis of traffic flow. It is relevant for designing new roads or interchanges to evaluate the economic and environmental impacts. Foreign experience proves that traffic modelling software is being used before implementing modernization of road network. Traffic simulation models become more and more important tools ensuring traffic control and providing possibility to do the planning process of road network. The main goal of study is to create traffic simulation models using modern software which will enable efficient selection of road design solutions in Lithuania. During the research below studies traffic modelling software packages were analysed, traffic simulation models were designed using traffic modelling tools and calibration of traffic simulation models was made so as their adaptation to Lithuanian conditions. Traffic simulation models adapted to designing of road infrastructure and the process of selection of solutions. The results showed that road design solutions can be compared based on traffic simulation models. Thus a high level of design solutions is being ensured. Two Lithuanian study cases of using traffic modelling in infrastructure design projects are described in the article.
