The article discusses the algorithms of the population's choice of the method and means of transportation around the city. The article presents three algorithms: the general algorithm, the algorithm for regular movements and the algorithm for urgent movements. The logic used in the developed algorithms is based on the materials of a survey of 1504 respondents in Tyumen in 2021. The algorithms take into account aspects that are associated with the risk of COVID-19 infection in urban transport. These algorithms can be used in research works to simulate the process of movement of city residents.
