Crashes at rail level crossings represent a significant problem, both in Australia and worldwide. Advances in driving assessment methods, such as the provision of on-road instrumented test vehicles, now provide researchers with the opportunity to further understand driver behaviour at rail level crossings in ways not previously possible. This paper gives an overview of a recent onroad pilot stu...

This report evaluates rail transit benefits based on a comprehensive analysis of urban transportation system performance in major U.S. cities. It discusses best practices for evaluating transit benefits. It finds that cities with larger, well-established rail systems have significantly higher per capita transit ridership, lower average per capita vehicle ownership and mileage, less traffic cong...

Currently most modern dc rapid transit systems around the world use running rails or a negative rail as the negative return circuit for the dc traction current. These rails are intentionally kept ungrounded from ground (earth) by using insulating material between the rail and earth to minimize dc stray current. This configuration of return current rail develops varying voltage with respect to g...

In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...

The type and magnitude of loads passing through the track superstructure have a great impact on both the design and the performance of concrete sleepers and fastening systems. To date, the majority of North American research focusing on quantifying rail infrastructure loading conditions has been conducted on heavy-haul freight railroads. However, the results and recommendations from these studi...

nowadays, the use of small vehicles is spreading among urban areas and one sort of these vehicles are three-wheeled vehicles (twvs) which can be competitive with four-wheeled urban vehicles (fwvs) in aspects such as smallness, simple manufacturing, and low tire rolling resistance, fuel consumption and so on. the most critical instability associated with twvs is the roll over. in this paper a ti...

in this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. for vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. in accordance...

The aim of the study was to investigate rail vehicle dynamics under primary suspension dampers faults and explore possibility its detection by means artificial neural networks. For these purposes two types analysis were carried out: preliminary 1 DOF model a second one - passenger coach benchmark tested in multibody simulation software MSC.Adams with use VI-Rail package. Acceleration signals ob...

The simultaneous prediction of wheel surface wear is one the most challenging tasks in railway field, which requires knowledge vehicle–track dynamics, rolling contact mechanics, and other tribological phenomena. In this paper, a new model for predicting profile presented to study detail characteristics railway. able consider effect track flexibility on evolution. proposed modelling approach inc...
