Modeling vehicle flows is impossible without the introduction of IT. The study is aimed at developing models for the choice of routes, considering the individual characteristics of drivers, which are determined by the type of nervous system. On the basis of the analysis, the factors influencing the choice of the route by the drivers were identified. To fix the values of the obtained factors, a survey was carried out using a specially developed questionnaire. The type of the driver's nervous system was determined using a typological questionnaire. On the basis of the data obtained during the survey of drivers of vehicles, models were developed for changing the proportion of correspondence carried out along alternative routes of movement when driving drivers with different types of nervous systems. Based on the results obtained, it is possible to model the transport network, rationalize the development and planning of traffic flows, which are possible through the introduction of information technologies.
