MIPT mathematicians, together with specialists from the Russian University of Transport (RUT), are creating a computer program for modeling traffic flows in a city, Izvestia learned.
Model calculations should show how citizens will be distributed over the transport system of the settlement in the event that certain changes are made to it, how much time they will spend on the road, and so on. Thanks to this, traffic jams can be avoided.
Unlike previous developments, the new program is based on the most modern and efficient calculation methods, which make it possible to obtain the desired indicator, the so-called equilibrium point, with a guarantee. This is such a distribution of city residents along the roads, in which none of them wants to change their route.
“In order to understand how people will be distributed along the transport network graph under various scenarios for upgrading the existing infrastructure, it is not enough just to take statistical data. It is necessary to learn how to model the distribution of traffic flows. Ultimately, our goal is to find their equilibrium distribution according to the chosen model,” Alexander Gasnikov, head of the project’s scientific group, told Izvestiya.
According to MIPT scientists, today Russian specialists often use foreign-made software packages for such calculations, which are based on algorithms developed more than 30 years ago. Such software does not take into account many modern realities, for example, the data of mobile operators, which simply did not exist during the development of the package.
Plus, over the past decades, mathematical modeling has reached a new level. It uses new, more modern approaches.
