Applications based on the Global Navigation Satellite System (GNSS), in combination with different communication systems, have significantly helped to increase safety, efficiency and system capacity of operations in different modes of transportation. Here railway transport is no exception, although the number of applications based on GNSS has been considerably behind the number of those used in...

This paper constructs an additive two-stage network DEA (data envelopment analysis) model with consideration of undesirable outputs and shared inputs. Following the triple bottom line standard of sustainability, we calculate both the overall and sub-stage sustainability performance of railway transportation in China from 2002 to 2013, from the aspects of economy, environment and society. The re...

In this paper we present conflict resolution measures in connection dispatching suitable for railway transportation companies without having full access to relevant data. The presented measures do not only cover classical waiting/non-waiting-strategies but also alternative dispatching measures if a distributor train cannot wait. The fact of unknown travel chains and insufficient data availabili...

An experimental study was performed to compare the annoyances from civil-aircraft noise, military-aircraft noise, railway noise, and road-traffic noise. Two-way within-subjects designs were applied in this research. Fifty-two subjects, who were naive listeners, were given various stimuli with varying levels through a headphone in an anechoic chamber. Regardless of the frequency weighting networ...

This paper deals with the design of timetables for complex railway systems. Rail transportation has become a rapid, clean and efficient way to transport passengers and freights. A good timetable design is crucial to ensure the quality of the services trying to improve the efficiency of the whole system. Only such a sustainable transportation system will be in accordance to the requirements of f...

Long lead times in railway planning can give rise to a significant discrepancy between the original plan and the traffic eventually operated, resulting in inefficient utilization of capacity. Research shows that the railway sector in Sweden would benefit from a different planning approach in which capacity consuming decisions are pushed forward in time whenever possible. This approach is curren...
