Traffic congestion is a major problem in urban areas that has a significant adverse economic impact through deterioration of mobility, safety and air quality. As a result, the importance of better management of the road network to efficiently utilize existing capacity is increasing. To that end, many urban areas build and operate modern Traffic Management Centers (TMCs), which perform several f...

MATSim is a mature and powerful traffic simulator, used for large scale traffic simulations, primarily to assess likely results of various infrastructure or road network changes. We have coupled MATSim with the BDI system GORITE to provide additional valuable functionality within MATSim, and have demonstrated this with an application combining BDI taxis with standard MATSim traffic agents. Alth...

Applications by simulation are known worldwide, and more and more complex systems can be analysed by this tool because of rapid development of computers. The traffic modelling, as application field is in similar state, there are currently at least 50 traffic simulators in Europe with varying qualities of functionality. Rather than developing one more traffic simulator, it would be more useful t...

The study of Quality of Service (QoS) has become of great importance since the Internet is used to support a wide variety of new services and applications with its legacy structure. Current Internet architecture is based on the Best Effort (BE) model, which attempts to deliver all traffic as soon as possible within the limits of its abilities, but without any guarantee about throughput, delay, ...

A framework of dynamically adaptive hardware mechanism on multicontext reconfigurable devices is proposed, and as an example, an adaptive switching fabric is implemented on NEC’s novel reconfigurable device DRP(Dynamically Reconfigurable Processor). In this switch, contexts for the full crossbar and alternative hardware modules, which provide larger bandwidth but can treat only a limited patter...

This thesis describes the design, analysis, and implementation of FIG—a tool that records, analyzes, and plays ETMS air traffic data feeds. Its creation was motivated by the need to test air traffic control applications against a static source of air traffic data. Three fundamental requirements of the system are: 1) maintain the fidelity of the original ETMS feeds, 2) store feed data in portabl...

Next-generation Internet gateways are expected to deal with higher volume of network traffic and also performmore sophisticated tasks besides packet forwarding.As the scale-up approach does not escape from the tradeoff between functionality andperformance, architectural improvements such as clustering become necessary in the design of future Internet gateways. In this paper, we investigate diff...

This paper describes the development of a video-based system for traffic surveillance that works in real-time on a standard PC-platform. The main task of the system, which was developed for and in co-operation with Axicon, is to count passing vehicles to estimate traffic density. More functionality can also be developed on top of this to derive other traffic parameters. The methods use low-leve...

Generalized Multiprotocol Label Switching (GMPLS) is being applied to optical networks as a means of moving control functionality from the management plane to the control plane, and automating lightpath provisioning and maintenance. GMPLS enables IP networks with Quality of Service (QoS) to be traffic engineered efficiently. However, computation of explicitly-defined paths optimizing network pe...

Platforms at the edge of the network, such as MultiService Switches (MSS) and edge routers, convert traffic from legacy networks to Internet Protocol (IP) traffic for transport across the network core. Line and service cards in these platforms will have to handle traffic in a wide range of protocols and line rates. Current silicon solutions for edge applications are limited in functionality and...
