Transport is associated with environmental problems, economic losses, health and social inequalities. A number of European and US cities have implemented initiatives to promote multimodal modes of transport. In Latin America changes are occurring in public transport systems and a number of projects aimed at stimulating non-motorized modes of transport (walking and cycling) have already been imp...

Road traffic contributes a major share of emissions and energy consumption. A shift to other transportation modes is often seen as an approach to combat the emissions. A shift is not always possible in some regions where other transportation modes are not sufficiently developed due to low population density or other reasons. This paper discusses possibility of combating emissions and energy con...

INTRODUCTION The purpose of this multicenter study was to assess differences in demographics, medical history, treatment times, and follow-up status among patients with ST-elevation myocardial infarction (STEMI), who were transported to the hospital by emergency medical services (EMS) or by private vehicle, or were transferred from other medical facilities. METHODS This multicenter study invo...

Arrival performance for the United States shows that over 83 percent of flights are actually on time. However, 17 percent delayed flights are still an indisputable high number, having almost eight million commercial travel flights per year, only in the US. Knowledge of the conditions leading to flight delays may be used in a monitoring and prediction tool to diminish its impact on commercial fl...

The aim of this paper is to show that different transport modes between whites and nonwhites lead to different search intensities. We develop a theoretical model in which whites mainly use cars to commute whereas nonwhites use public transportation. We show that, for both whites and nonwhites, living in areas where employed workers’ average commuting time is higher yield the unemployed to searc...

In an attempt to better understand the current transportation situation in Santiago de Chile, this paper provides a framework within which persona1 expenditures, environmental consequences and social effects can be measured by a common metric, costs. The analysis includes all modes of transport, but has a specific focus on passenger transport modes. The paper presents the cost categories consid...

Numerous algorithms have been proposed to solve the shortest-pathproblem; many of them consider a single-mode network and crispcosts. Other attempts have addressed the problem of fuzzy costs ina single-mode network, the so-called fuzzy shortest-path problem(FSPP). The main contribution of the present work is to solve theoptimum path problem in a multimodal transportation network, inwhich the co...

Understanding and discovering knowledge from GPS (Global Positioning System) traces of human activities is an essential topic in mobility-based urban computing. We propose TrajectoryNet—a neural network architecture for point-based trajectory classi€cation to infer real world human transportation modes from GPS traces. To overcome the challenge of capturing the underlying latent factors in the ...

This paper attempts to solve a comprehensive design problem for a spare part logistic system. The design factors encompass logistic network design, part vendor selection, and transportation modes selection. Two approaches to solve the problem were proposed. In Approach 1, we simultaneously considered all the design factors and proposed two algorithms (SGA-1 and TGA-1). In Approach 2, the design...

In a network with different transportation modes, or multimodal public transportation system (MPTS), modes are linked among one another not by resources or infrastructure elements which are not shared, e.g., between different metro lines , but by the flow of passengers between them. Now, the movements of passengers are steered by the destinations that individual passengers have, and by which th...
