Innovative Industrial Technologies for Preventive Anti-Graffiti Coating
2017
Graffiti is the main issue in terms of acts of vandalism with public transport. Hardly any suburban train, commuter train or goods train, hardly any engineering building, station or noise barrier wall escape graffiti spraying. This means enormous expenses every year which one would rather use to the benefit of its customers. Furthermore, the temporary and permanent anti-graffiti protection systems used up to now do not ensure adequate graffiti protection. The costs for the application of graffiti protection and/or graffiti removal to a large part depend on the circumstances of the individual case in question, i.e. on the size of the surface, the type and size of the ground, the accessibilit…
Rail freight transport and demand requirements : an analysis of attribute cut-offs through a stated preference experiment
2014
This paper analyses the choice between road and rail in Spain where rail market share for freight is still residual. Discrete choice models are estimated with data obtained through a two-phase fieldwork, thus allowing us to carry out a stated preference efficient design for each interviewee. We analyse the existence of attribute cut-offs and the presence of a segment of the population with a zero value of frequency. Our results show that ignoring the existence of cut-offs and segments of the population with polarised valuations can lead to erroneous conclusions in terms of the possibilities of rail for absorbing significant quota.
Two-Player Noncooperative Games over a Freight Transportation Network''
2004
A game between two players acting on the same road transportation network is considered in this paper. The first player aims at minimizing the transportation costs, whereas the second player aims at maximizing her profit (or, in general, her utility) that is proportional to the flow passing through the arcs under her control. We introduce bilevel linear programming formulations for this problem. We derive conditions of existence and properties of the equilibrium points and propose an algorithm finding a local optimal solution. Finally, we present an application of the model to a real system involving trucks travelling through Europe from a Middle Eastern country.
Principles of Calculation of Track Access Charges in Rail Freight Transport in Poland
2019
Non-discriminatory rules for access to the railway infrastructure as well as transparent pricing system are the essential factors of ensuring that the freight transport in Poland is competitive enough. Infrastructure managers pass some categories of their costs (e.g. for maintaining of railway infrastructure) on railway undertakings in the form of access charges verified andaccepted by the Polish regulatory body. In general, approximately one – third of their costs shall be paid by railway undertakings. Given that access charges are treated as one of the most important factors for both railway undertakings and railway infrastructure man-agers. The aim of this article is to review the main p…
Techno-economical inspection of high-speed Internet connection for trains
2008
Some attractive service scenarios for Railways' Intelligent Transport Systems (RITS) in three different user segments, that is, passengers, freight companies and train operator's in-house customers, are presented. The case study covers the analysis of customer needs and techno-economic evaluations. The analysis indicates that Flash-OFDM technology provides promising pre-stage solution for the train connections in Finland. Also, the WiMAX-based high-speed Internet access for passengers may be profitable in the most heavily operated railway leg in Finland. The sensitivity analysis shows that the most crucial parameters for the case are `User Share', `Average Revenue per User' and `WiMAX Cell …
Taste heterogeneity and latent preferences in the choice behaviour of freight transport operators
2013
In this paper we show that individual attitudes of road carriers and their latent preferences toward specific freight service attributes do play a role in determining their mode choices. Specifically, we contribute to the empirical literature on freight agents' mode choice by exploring the role of the "perceived importance" of the most relevant service dimensions in determining the attractiveness of two alternatives to "all-road" transport: logistics terminals and road-sea intermodal services. This is carried out through a revealed/stated preference experiment and a mixture of logit framework. Our results support the hypothesis that operators' attitudes towards time, punctuality and risk of…
