文摘
We present a design paradigm for a cloud-based service for interactive modeling of traffic flows in a developing urban infrastructure. The mathematical forecasting model for the load of a transportation network is constructed as a result of synthesizing a gravitational model that describes origin-destination trips and a multimodal traffic equilibrium problem with elastic demand. The search for traffic equilibrium reduces to solving a variational inequality. Three-dimensional visualization of the transportation network and adjacent infrastructure is implemented with the virtual environment’s declarative model.
