The Committee on Railroad-Highway Grade Crossings is concerned with the safety and other affected characteristics (including economic considerations, traffic flow and delay, and countermeasures) of both highway and rail traffic at points where they intersect at grade, including the proximate surrounding environment and rail transit facilities. This is a white paper on the state of the art and t...

high speed intercity passenger rail is an inherently strong railway application. it operates over 250 km/hour. for perspective, high-speed represents the ultimate development of preexisting standard gauge infrastructure. network of high-speed passenger rail lines aimed at reducing accident, reducing traffic congestion, air pollution cutting national dependence on foreign oil and improving rural...

Broken rails are the most common cause of severe freighttrain derailments on American railroads. Reducing the occurrence of broken-rail-caused derailments is an important safety objective for the railroad industry. The current practice is to periodically inspect rails using non-destructive technologies such as ultrasonic inspection. Determining the optimal rail defect inspection frequency is a ...

The train derailment is one of the major accidents in rail transit safety system. The reach uses collision accident of rail transit train in Tokyo and Shanghai as the case. Firstly, it present fishbone diagram to qualitatively analysis main factors in derailment. Then it set up a derailment accident tree model with the qualitative and quantitative analysis of. The results show that illegal oper...

The neglectof the rail sector in Brazil that went on for decades is fortunately being overcome, especially in the metropolitan region of São Paulo, with the subways and monorails, an example to other Brazilian metropolitan regions. The historical disconnection between the passenger transport modals combined with the increasing private vehicle fleet and the lack of investment in mass transit sys...

The development of High Speed Rail (HSR) in Europe has been encouraged and financially supported by the European Commission. Several lines are in operation, and many others under construction or waiting for approval. HSR technology is presented as a solution to congested roads and airports. Besides, rail transport is generally regarded as more environmentally friendly than other modes. However,...

INTRODUCTION: It is a well known fact that noise annoyance depends on the traffic mode. Much less is known about differences in physiological effects, especially on combined effects. Therefore, we investigated the effects of air (AI), road (RO) and rail (RA) traffic noise on sleep in the AIRORA study. METHODS: 72 subjects (40 ± 13 years, 32 male) were polysomnographically investigated during 11...

Railway traffic causes both noise and vibrations in surrounding areas. To enable effective planning of reduction measures that may reduce adverse health effects, it is important to gain a better knowledge about the coupling of these effects to noise and vibration exposures from train and road traffic. These exposures may in fact increase in the future, due to increasing traffic intensity with b...
