Driverless vehicles will be common on the road in a short time. They will have many impacts on the global transport market trends. One of the remarkable driverless vehicles impacts will be the laying aside of rail systems, because of several reasons, that is to say traffic congestions will be no more a justification for rail, rail will not be the best answer for disableds, air pollution of cars...
Abstract The research examines the sources of rail transport noise. Noise depends on type locomotives, warning signals, maintenance, and construction equipment. wheel–to–rail contact rolling stock locomotives’ propulsion systems are noise sources. Static dynamic loads have intensities that depend masses speeds trainsets. In addition, static, stock, thermal loads, action rainwater stress ballast...
The demand for freight rail transportation in North America is anticipated to substantially increase in the foreseeable future. Additionally, government agencies seek to increase the speed and frequency of passenger trains operating on certain freight lines, further adding to demand for new railway capacity. The majority of the North American mainline railway network is single track with passin...
The author investigated the status of barrier-free facilities of urban rail transit station in China. Due to the physical factors, the senior and disability population fail to utilize urban traffic facilities, like ordinary persons. Also, children, women of pregnancy, and those who have mobility difficulties, and those who bear heavy loads are also not able to conveniently use urban traffic fac...
The paper explains a new advanced rail traffic management system that combines real-time rescheduling with an advanced train control tool being developed by the Swiss Federal Railways (SBB) in cooperation with the Swiss Federal Institute of Technology (ETH). The system is designed to increase network capacity and stability in heavily used mixed traffic networks while minimizing the cost of new ...
Ultrasonic Non Destructive (NDT) inspection frequency needs to be decided based on probability of rail breaks and derailments along with cost of inspection, planned maintenance and corrective maintenance. This paper is on development of probabilistic model for NDT inspections. Undetected defects can lead to rail breaks based on the ageing, and tonnage passed through the line after the defect is...

Many governments subsidize regional rail service as an alternative to road traffic. This paper assesses whether increases in service frequency reduce road traffic externalities. We exploit differences in service frequency growth by procurement mode following a railway reform in Germany to address endogeneity of service growth. Increases in service frequency reduce the number of severe road traf...
This report investigates the role that public transit can play in reducing traffic congestion. Investigates the role that public transit can play in reducing traffic congestion. This analysis indicates that high quality public transit tends to reduce congestion by attracting travelers who would otherwise drive. As public transit service improves on a corridor (including improved speed, convenie...
Long term demand for rail transportation in North America is projected to increase considerably in the coming decades. A significant portion of the routes in the United States are single track with passing sidings. Eventually, the second mainline track will become necessary to maintain network fluidity. However, the full funding for the second track may not be available all at once; subsequentl...
