Hierarchical Modeling and Simulation Environment for Intelligent Transportation Systems

Abstract: This article presents a hierarchical and modular traffic simulation environment for intelligent transportation systems (ITS).A conventional traffic simulation model is classified as microscopic or macroscopic; however, abstraction-level, vehicle-level, cell-level, road-level, and street-level traffic models can be coherently integrated and developed. Such an abstraction process is important for flexible traffic analysis since it reduces the complexity of a model, retaining its validity relative to the modeling objectives and experimental condition. To do this, the authors have proposed the four-layered approach: (1) system entity structure/model base, (2) model abstraction, (3) traffic modeling, and (4) ITS simulation systems layer.A proposed methodology has been successfully applied for building the advanced traveler information system and the advanced traffic management system.The abstraction method of a road network in traffic modeling and simulation will be widely used because it is possible to express and analyze various requirements of the traffic analyst hierarchically and structurally.

Method of managing traffic flows in a wideband integrated services digital network, and a network for implementing the method

Abstract: Method and apparatus for controlling traffic flow in a wideband integrated services digital network including an asynchronous time division multiplexed switch network and a plurality of terminals operating at various data rates and providing different types of service. Control of traffic flow in the network is achieved by delaying data cells or allowing them to be lost, within limits that are predetermined as a function of the type of service provided by the terminals.

Resource allocation for wireless networks

Abstract: We examine several methods to allocate radio frequency channels across a cellular network. In this paper we consider centralized channel assignment strategies that utilize global network traffic information. The channel assignment methods considered are linear programming, quadratic programming, and a heuristic algorithm to assign resources given the network traffic loading. Each method attempts to assign resources, under frequency reuse constraints, to achieve a desired target performance measure for the network. The network performance measures used in this paper are the average and maximum probability of blocking across the network. We compare the performance of a linear highway network and a planar network using our assignment methods to those of uniform fixed channel allocation (FCA) for non-uniform network traffic loading. We show that under non-uniform traffic loading a better grade-of-service can be provided to network subscribers than by fixed channel assignment. >

Network controller normalization of network traffic

Abstract: Methods, devices, and machine-readable and executable instructions are provided for normalizing network traffic using a network controller. An example method for normalizing network traffic using a network controller can include receiving network traffic, including a plurality of data units, at a network controller, and normalizing the network traffic based on a rule using the network controller.
