The study results reported here are part of a larger research project that developed a manual for practitioners to improve safety at rail transit platform/train and platform/guideway interfaces. As part of that effort, passenger injury incident data was collected from five rail transit systems, and interviews were conducted with safety officers at other rail transit systems in the US and Canada...

Methods for multibody modelling and simulation should accurately replicate the dynamic behaviour of rail-wheel interface including precise values for wheel-rail contact positions. This paper studies the development of a novel 3-D wheel-rail contact model which is used for dynamic simulation of a suspended wheelset with parameters listed for a typical Mark IV coach. The contact point locations o...

Dry port is an inland intermodal terminal directly linked by road or rail to a seaport as a center for the transshipment of sea freight to inland destinations. However roads contribute to pollution more than rail. For sustainable transportation systems, we need to improve the performance of rail dry port systems. The purpose of this research is to propose a diagnostic system for modeling and cl...

Detailed yet computationally efficient simulation models are needed to support the design and operation of modern rail infrastructure systems. LIBROS-II is a model component library for microscopic rail operations simulation. Basic rail elements are modeled as atomic DEVS models which are further aggregated into more elaborate rail component models. The latter can in turn be used modularly for ...

Compact low-voltage power-efficient operational amplifiers are described that are very suitable as very-largescale-integration library cells because of the small die area of 0.08 mm and the minimum supply voltage of 1.8 V. A key part of the circuit is the rail-to-rail class-AB output stage with folded mesh feedback control that combines power efficiency with operation down to 1.8 V and allows s...

Liberalisation process has just started in the Turkish rail market with the new law recently entered into force in order to comply with EU Directives. In the liberalised markets, service quality is the decisive factor that rail undertakings can use to create difference and achieve competitive advantages. The purpose of this paper is to analyse the customer perceived service quality for rail fre...

An overall objective of the REORIENT project is to develop a business case for a new rail service between the Nordic countries and countries in Centraland South Eastern Europe. We developed, conducted, and used information from a survey conducted by the REORIENT project among intermodal freight shippers in countries within the REORIENT Corridor to identify essential factors for attracting freig...

Railway transport is a type of transport which is commonly used today. Rail line must be robust due to the heavy structure of the railway vehicles. Components constituting the rail line are very important to prevent the disruption of transportation. In this study, faults are determined by monitoring the rail and fastening components constituting the railway. Test vehicle was used to get experim...

A novel design method of asynchronous domino logic pipeline, which focuses on improving the circuit efficiency and making asynchronous domino logic pipeline design more practical for a wide range of applications. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical ...

This project presents a high-throughput and ultralowpower asynchronous domino logic pipeline design method, targeting to latch-free and extremely fine-grain or gate-level design. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical data path, the handshake circuits ...
