Scoping assessment of free-field vibrations due to railway traffic

Analysis of Structural Vibrations due to Passage of Underground Trains

During the last decades, the railway traffic in densely populated areas has increased. At the same time, passenger trains have become faster and freight trains have become heavier. Consequently, trains are an increasing source of ground vibration, which may be a nuisance to people, buildings and sensitive equipment. In this research, a two-dimensional dynamic system, including underground train...

Valuing Reduction of Risk of Mortality Due to Traffic Accidents

Background and Aim: The trade-off between monetary wealth and fatal safety risks is explained by the value of statistical life, an efficient tool widely used to evaluate projects and allocate appropriate resources for road safety. The objective of this study was to estimate the statistical significance of life in order to improve road safety in the city of Ardabil, Iran. Materials and Methods:...

Assessment of South Pars Gas Field Subsidence Due To Gas Withdrawal

Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction. Reservoir compaction will result in surface subsidence through the elastic response of the subsurface. Usually in order to determine the subsidence above a hydrocarbon field, the reservoir compaction must be first calculated and then the effec...

Annoyance Due to Railway Traffic Noise: Assessment of the European Union Dose-effect Relationships and of the Annoyance Equivalents Model When Combined with Road Traffic and Aircraft Noises

In 2012, a survey was carried out in 8 French cities to study noise annoyance due to combined transportation noise sources. Both partial and total annoyances were measured. The current paper will first focus on partial noise annoyance due to railway traffic measured in 6 French cities. In order to predict annoyance due to single transportation noise sources, the European Commission recommends t...
