This research aims to identify the role of network architecture in influencing individual travel behavior using travel survey data from Minneapolis-Saint Paul and Florida (Fort Lauderdale and Miami). Various measures of network structure, compiled from existing sources, are used to quantify roadway networks, and to capture the arrangement and connectivity of nodes and links in the networks and ...

During the transition from IPv4 to IPv6, it is necessary to provide IPv6 access service for IPv6 islands inside the native IPv4 network to access the native IPv6 network. The existing IPv4/IPv6 transition methods make IPv6relay gateways maintained by IPv6 service providers become potential communication bottlenecks. In this paper, a new method PS6 is presented to reduce the reliance on these re...

Two important recent trends in military and civilian communications have been the increasing tendency to base operations around an internal network, and the increasing threats to communications infrastructure. This combination of factors makes it important to study the robustness of network topologies. We use graph-theoretic concepts of connectivity to do this, and argue that node connectivity ...

While the layered OSI model for networks provides a very clean conceptual framework for network design, certain applications are not completely indifferent to what happens at the lower layers. This is particularly true for multimedia and other real–time applications, which usually have stringent constraints on network performance in order to deliver an acceptable Quality of Experience (QoE) to ...

Nowadays operational research (OR) claims to be known as the science of better by the scientific community and by the industry. OR provides a set of techniques and tools for thinking, analysing and solving, which leads to taking decisions in a structured and focused way towards efficiency and optimality. Due to these aspects, the advance of telecommunications research has been strongly linked t...

We provide information on the Survivable Network Design Library (SNDlib), a data library for fixed telecommunication network design that can be accessed at http://sndlib.zib.de. In version 1.0, the library contains data related to 22 networks which, combined with a set of selected planning parameters, leads to 830 network planning problem instances. In this paper, we provide a mathematical mode...

In this paper, we focus on a number of applications of network optimization techniques to transportation systems analysis. In particular, network analysis problems, network design problems, and network management problems are discussed in some detail. The intent is to survey important application areas.

Understanding and preventing overrtting is a very important issue in artiicial neural network design, implementation, and application. Weigend (1994) reports that the presence and absence of overrtting in neural networks depends on how the testing error is measured, and that there is no overrtting in terms of the classiication error (symbolic-level errors). In this paper, we show that, in terms...

This is the second part of a two-part survey investigating transportation network postdisaster planning and management. The first part focused on efforts and models for the estimation and assessment of post-disaster network performance (PDNP). This paper addresses the problem of decision-making and planning of post-disaster network operations (Post-Disaster Network Operations Planning – PDNOP)....
