بخش حملونقل در اقتصاد هر کشور اهمیت خاص خود را دارد که با گستردگی فعالیتهای اقتصادی و افزایش تولید ملی نیاز به توسعه و بهبود شبکههای حملونقل بهخوبی احساس میشود. بر این اساس هدف از این مطالعه بررسی عوامل موثر بر جابجایی مسافر در ایران و پیشبینی تعداد مسافر جابهجا شده توسط حملونقل ریلی است. این کار تحقیقی برگرقته از مطالعه چن در سال 2007 میلادی است. متغیرهای مورد استفاده در این تحقیق، ت...
With the construction of high-speed railway lines in China, there are growing concerns about the rational transport cooperation between high-speed railway lines and conventional rail lines. A rational transport cooperation scheme can improve railway capacity utilization, train speed, service and the organization quality of railway transportation. The previous research mainly focused on the aspe...
The North American freight railroad network is projected to experience rising transportation demand in the coming decades, leading to increased congestion on many rail lines. Capacity is further strained by increased interest in increasing the speed and frequency of passenger service on shared rail corridors. Since passenger trains in North America predominantly operate on corridors where freig...
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...
Contamination of rail lines with leaves and other organic matter oxides can affect the traction train wheels cause safety issues, delays schedule changes. The main solution in UK is to use specialist rail-head-treatment trains that clean rails high-pressure water jets. But these cannot cover all mainline infrastructure due limited availability gauging issues. As such, there a need for rapid-res...
The North American freight railroad network is projected to experience rising transportation demand in the coming decades, leading to increased congestion along many rail corridors. Increased interest in expanded passenger service on shared rail corridors will also create additional capacity demand. However, the nation’s rail lines are still predominantly single track with passing sidings, maki...
Reduced travel time, regional cohesion, economic development and environmental benefits were some of the reasons given to develop the High Speed network in Spain, the largest in Europe. Ever since the opening of the first High Speed line in 1992, High Speed Rail (HSR) have become a new travelling experience despite the fact that in the recent years several voices have raised concerns over a lac...
At present, there are few research results on the seismic response of track system railway suspension bridges, and relevant has not yet formed a certain standard. In order to provide reference for development industry standards design seamless lines based large-mass method multi-point excitation, taking China’s longest high-speed bridge-Wufengshan Yangtze River Bridge as engineering background,...
