EU regulations require that public transportation systems are accessible for everyone without any restrictions for People with Reduced Mobility. This does not only refer to disabled people, but also other groups of people with reduced mobility such as elderly people, passengers with baby prams, outsize and large luggage items etc. i.e. all people with some kind of reduced mobility, in order to ...
Track Maintenance is crucial for the safe and efficient of railway transportation. After analysis of foreign management techniques for high-speed railway track maintenance, combined with the characteristic of passenger dedicated line in China, this paper has explored new ideas of the information system of passenger dedicated line track maintenance and at the same time researched on the theory a...
This article gives an overview of the results of the author’s PhD thesis Schlechte [2012]. The thesis deals with the mathematical optimization for the efficient use of railway infrastructure. We address the optimal allocation of the available railway track capacity the track allocation problem. This track allocation problem is a major challenge for a railway company, independent of whether a fr...
Satellite-based localization technologies are strategic opportunities in railway applications because they offer new possibilities of service and have advantages that current technologies relying mainly on infrastructures deployed along tracks cannot equal. GNSS (Global Navigation Satellite Systems) can, in particular, offer localization services in ERTMS (European Rail Traffic Management Syste...
Reliability is one of the key factors in transportation, both for passengers and for cargo. This paper examines reliability in public railway systems. Reliability of railway services is a complex matter, since there are many causes for disruptions and at least as many causes for delays to spread around in space and time. One way to increase the reliability is to reduce the propagation of delays...
RFID technology has been widely utilized for the tracking and identification of numerous stationary and moving objects. One of the most challenging RFID applications has to do with the improvement in reliability, scheduling and efficiency of large‐scale transportation infrastructure. As an example, Radio Frequency Identification (RFID) technology in Ultra High Friency (UHF) frequen...
High-speed railway is a very important part of transportation industry in China, and travel choice has key effect on the development of high-speed railway. Therefore,research on travel behavior of passengers and prediction their travel choice, will offer valuable suggestion for high-speed railway running. In this paper, support vector machine (SVM) is the main method being used to predict. Supp...
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...
