In Essex, EssexITS (a joint partnership of Essex County Council, Atkins and Siemens), has taken a hands-on approach to assist the County Council in carrying out its responsibility under TMA2004. EssexITS has developed a number of Integrated Urban Traffic Management and Control (UTMC) strategies to manage Essex’s road network, tackle congestion and proactively prevent or reduce the effect of con...

In the recent times many accessible congestion control procedures have no capability to differentiate involving two major problems like packet loss by link crash and packet loss by congestion. Consequently these resolutions effect in form of wastage of possessions because they target only on the packet drop by link crash that has a needless importance. Consumption of energy and possessions in o...

In this paper, we propose a new network management protocol to address the unique challenges of managing cognitive radio ad hoc networks that have distributed, multihop architectures with dynamic spectrum availability. We focus on performance management for these networks, and address the problem of network congestion for secondary users, because of its significant impact on data throughput. Sp...

A common way of dealing with large urban transport infrastructures is by using Urban Traffic Management and Control (UTMC) systems [1][2]. The UK Department for Transport led Urban Traffic Management and Control initiative recognizes the following common UTMC components: strategic network management, comprehensive performance monitoring, traveller information, congestion monitoring, streamlined...

In this paper we study the design issues for improving TCP performance over the ATM UBR service. ATM-UBR switches respond to congestion by dropping cells when their bu ers become full. TCP connections running over UBR can experience low throughput and high unfairness. Intelligent switch drop policies and end-system policies can improve the performance of TCP over UBR with limited bu ers. We des...

O ne of the greatest challenges in the management of patients with chronic heart failure is forecasting and preventing the development of acute worsening leading to hospitalizations. Despite current best practice guidelines, including management within a heart failure clinic, early follow-up after hospitalizations, measuring daily weights, and frequent patient contact, rehospitalization for hea...

Even though there is a commonality in their physical and link layers, Advanced Switching (AS) is more than merely an extension of PCI Express. The role of PCI Express is primarily as a chip-interconnect. In contrast, AS functions as a true system fabric interconnect encompassing domains that are vastly different and indeed more sophisticated than that of PCI Express’. In such a setup, congestio...

Congestion management is one of the technical challenges in a Deregulated power system environment. Two types of Methodologies used in congestion Management are non-cost free methods and cost free methods. In this research work congestion is relieved by using cost-free methods considering FACTS Devices such as TCSC(Thyristor controlled series Compensator) and UPFC (Unified Power Flow Controller...

How traffic congestion is evaluated can significantly affect transport planning decisions. This report describes various factors that affect congestion cost estimates and the evaluation of potential congestion reduction strategies, including analysis scope, baseline speeds, travel time valuation, accident and emission impact analysis, induced travel analysis, and consideration of co-benefits. I...
