In the United States, Light Rail Transit (LRT) systems have become a popular transportation alternative. Minnesota built its first light rail system in 2004 with the Hiawatha Line and additional projects are underway in the Minneapolis and St. Paul area. While light rail systems are attractive to commuters, they are expensive to construct and careful planning is ongoing to ensure their effectiv...

Recently, the number of studies involving complex network applications in transportation has increased steadily as scholars from various fields analyze traffic networks. Nonetheless, research on rail network growth is relatively rare. This research examines the evolution of the Public Urban Rail Transit Networks of Kuala Lumpur (PURTNoKL) based on complex network theory and covers both the topo...

Carbon pollution has become a sensitive topic across the globe in recent times. In Australia, incentive has been provided to industry in order to reduce carbon emissions in heavy polluting industries. The railway transportation system is one of the industries expected to reduce the emissions and contribute to a long term reduction strategy, although comparatively rail sector contributes much le...

BACKGROUND Neighborhood transportation infrastructure and public recreational facilities are theorized to improve the activity, weight, and cardiometabolic profiles of individuals living in close proximity to these resources. However, owing to data limitations, there has not been adequate study of the influence of timing and placement of new infrastructure on health over time. METHODS This pr...

Railroads play a key role in the transportation of hazardous materials in North America. Rail transport differs from highway transport in several aspects, an important one being that rail transport involves trains in which many railcars carrying hazardous materials travel together. By contrast to truck accidents, it is possible that a train accident may involve multiple hazardous materials cars...

In the current urban rail transit system, the levels of informatization and integration are not high. In order to change the traditional pattern of rail transportation operation and management, we propose an intelligent information platform of subway system based on Internet of things. Depending on the sensor nodes deployed in various functional departments of rail transport and the RFID techno...

ABSTRACT The quality of ride is predominantly controlled by the design of the secondary suspension in rail vehicles. That is why air springs are increasingly important suspension component in rail vehicles. This is necessary for higher preload, higher speed as well as improved ride dynamics and noise levels. These necessities have created an interest for modeling the air springs for the simulat...

Considerably less research has been done on modeling freight demand with disaggregate discrete models than on modeling passenger demand. The principal reason for this imbalance is the lack of freight demand data. Freight demand characteristics are expensive to obtain and are sometimes confidential. This paper analyzes the freight demand characteristics that drive modal choice by means of a larg...

In the era of the North American Free Trade Agreement (NAFTA), the public and private sectors are increasingly committed to the growth of transport-oriented infrastructure, including ports, highways, bridges, and rail facilities. In particular there has been much interest in international bridges spanning the Rio Grande, the roads and rail lines leading to these bridges, and the port facilities...
