The importance of routing and shortest path problems in the study of transportation networks is well-known. For instance, these are used to describe user behavior, to find equilibrium states of large-scale networks, and to evaluate the impact of network improvements and broader transportation policies. Thus, the development of efficient, behaviorally realistic algorithms is of paramount interes...

BACKGROUND A major benefit offered by telemedicine is the avoidance of travel, by patients, their carers and health care professionals. Unfortunately, there is very little published information about the extent of avoided travel. We propose to undertake a systematic review of literature which reports credible data on the reductions in travel associated with the use of telemedicine. METHOD The...

Transportation is one of the most important issues in today's cities. Urban trips and their spatial and temporal patterns influence and are influenced by other components and functions of the city. Information and communication technology have evolved rapidly over the last few decades and have influenced urban travel patterns in many ways. Numerous studies have attempted to study the effects of...

We show that every uniformly asymptotically affine circle endomorphism has a uniformly asymptotically conformal (UAC) extension to the complex plane. Then we use the UAC extension to construct the dual dynamical system, the dual annulus, and the dual circle expanding map.

Transport systems are more and more complex and have to evolve to integrate more connected entities (mobile devices, localized vehicles, etc.). It becomes critical to develop micro-simulation tools for mobility policies makers taking into account this fact. In this paper, we propose a multimodal travel simulator that allows for the understanding and the prediction of future status of the networ...

BACKGROUND In 2011, the Centers for Disease Control and Prevention and the New Jersey Department of Health used the New Jersey Behavioral Risk Factor Survey (NJBRFS), a state component of the national Behavioral Risk Factor Surveillance System (BRFSS) to pilot a travel health module designed to collect population-based data on New Jersey residents travelling internationally. Our objective was t...

We are witnessing increasing interests in the effective use of road networks. For example, to enable effective vehicle routing, weighted-graph models of transportation networks are used, where the weight of an edge captures some cost associated with traversing the edge, e.g., greenhouse gas (GHG) emissions or travel time. It is a precondition to using a graph model for routing that all edges ha...

The United Nations Environment Programme (UNEP) and the World Tourism Organization (WTO) define sustainable tourism as a “„Tourism that takes full account of its current and future economic, social and environmental impacts, addressing the needs of visitors, the industry, the environment and host communities”. It requires informed participation of relevant stakeholders and strong political lead...

This paper aims to study the locomotive routing problem (LRP) which is one of the most important problems in railroad scheduling in view of involving expensive assets and high cost of operating locomotives. This problem is assigning a fleet of locomotives to a network of trains to provide sufficient power to pull them from their origins to destinations by satisfying a rich set of operational con...

H7N9, a newly emerging virus in China, travels among poultry and human. Although H7N9 has not aroused massive outbreaks, recurrence in the second half of 2013 makes it essential to control the spread. It is believed that the most effective control measure is to locate the original infection source and cut off the source of infection from human. However, the original infection source and the int...
