A pricing methodology adapted to specific railroad infrastructures and the trains that use them is one way to ensure that railroad networks used by several different operators are used optimally. The diversity of railway networks (new lines and old lines) and services (long-distance and suburban passenger trains, freight trains, etc.) make it difficult to develop such a pricing methodology. Thi...
The rail freight carload service segment enables the distribution of freight volumes down to the unit of single rail cars, and stand as an important alternative to road transportation. However, this service segment is often associated with significant uncertainties and variations in daily freight volumes. Such uncertainties are challenging to manage since operating plans generally are establish...
The European Commission is developing a Single Transport Area and has promoted modal shift from road to rail achieve more competitive resource-efficient transport system [...]
Mass Rapid Transit using rail is a popular mode of transport employed by millions of people in many urban cities across the world. Typically, these networks are massive, used by many and thus, can be a soft target for criminals. In this paper, we consider the problem of scheduling randomised patrols for improving security of such rail networks. Similar to existing work in randomised patrols for...
According to the principle of urban transport integration and sustainable development, in this work, we study level connection between rail transit regular bus transport, construct an evaluation indicator system according characteristics system, use entropy weighting method (EWM) calculate weights indicators determine influence each on connection, a TOPSIS comprehensive model, which can make ov...
Intermodal goods transport is characterized by a main transport by rail, barge or seaborne vessel, preceded and followed by short in time but expensive road transport. Many times trucks pick-up or deliver a single container which leads to a full truckload vehicle routing problem in terms of economically efficient transport services. Time windows induced by the customer or due to external situat...
This paper addresses the impact of transport infrastructure projects of manufacturing employment in Thai regions. After a theoretical review we consider the impact of various transport modes: road, rail and ports. We find that roads and ports have a positive impact on industrial location, although the size of the impact is modest. Labor appears to be a more important location factor in Thailand...
Carbon pollution has become a sensitive topic across the globe in recent times. In Australia, incentive has been provided to industry in order to reduce carbon emissions in heavy polluting industries. The railway transportation system is one of the industries expected to reduce the emissions and contribute to a long term reduction strategy, although comparatively rail sector contributes much le...
Recent in situ observations during Critical Ionization Velocity (CIV) experiments under the CRIT project produced puzzling results, apparently at odds with current ClV theories. It is shown that incorporation in the theory of lower hybrid wave (LHW) instabilities of strong turbulence and finite size effects results in reconciliation of the theory with the observations.
