Abstract
В работе рассмотрена модель равновесного распределения транспортных потоков на сети из параллельных каналов с эластичным спросом на перемещение. Поставлена и решена оптимизационная задача, соответствующая данной модели. Функция эластичного спроса представлена несколькими частными случаями. В явном виде найдены: суммарный транспортный спрос, равновесные значения транспортных потоков и время перемещения по маршрутам. На примере экспериментальных данных представлено практическое применение полученных результатов.
The paper considers the model of the equilibrium distribution of transport flows on a network of parallel channels with an elastic demand for movement. An optimization problem corresponding to this model has been posed and solved. The elastic demand function is represented by several special cases. In an explicit form found: the total transport demand, the equilibrium values of traffic flows and the time of travel along the routes. On the example of experimental data, the practical application of the results obtained is presented.
