Measurement of the vertical loads transferred to the rail
2014
Num. 12
  The aim of the research is the study and setup of a Vertical Loads Measurement Station (SMCV) transmitted from the wheels to the rails during operation. The research was developed through... read all
A method for evaluating the frequency effect on the overall travel time
2014
Num. 10
In this article, a method to evaluate the effect of the frequency of transport service on the overall travel time is proposed for a given origin destination connection. In particular, a formula for... read all
An assessment model of the single-track line carrying capacity: influence of the signalling system and application to the Trans-Mongolian railways
2014
Num. 8
  The Trans-Mongolian railway represents an interesting study case within the Trans-Asian connections, since - in these years - they have been subject to radical upgrading intended to increase its... read all
Thermal simulator for traction chains of high-speed trains, application to ETR500-Frecciarossa
2014
Num. 6
  The article is structured as follows: it initially shows the theoretical principles, describing the use of circuit networks (thermal networks) to represent the thermal behaviour of electrical... read all
Visco-elastic modeling for railway track structure layers
2014
Num. 3
  This article proposes a method of calculation for evaluating stresses and strains in the track structure. This condition is calculated by modelling the single elements composing the structure,... read all
Modeling of port - freight village systems and loading units’ tracking functions
2014
Num. 1
  The study starts from the applications of tracking to the freight transport and faces the contribution to the inter-modality of the real time load units identification. The main problems hindering... read all
Short-term rolling stock rostering and maintenance scheduling optimization
2014
Num. 1
  This paper describes an optimization framework for rolling stock ros tering and maintenance scheduling at a busy workshop. A new mixed- integer linearprogramming formulation is provided for the... read all
Creep and wear study for contact wire of direct current catenary: comparison between Cu-ETP and CuAg0,1 contact wires
2013
Num. 10
  The increase of the speed and of the capacity in the railway operation requires an increase of the performances of both rolling stock and infrastructure. This paper is focused on the needed... read all
The “Hourglass” model
2013
Num. 8
  When there is an anomaly of the motorway traffic with drastic reduction of capacity, the almost immediate establishment of a queue is frequent. The note shows a generalized methodology to estimate... read all
Freight transport through the Swiss Alps: evolution as determined by application of a new model of modal split
2013
Num. 6
  The paper presents a dynamic model of demand modal split in a multimodal freight transport system. It has been devised in order to study the evolution of freight transport through the Swiss Alps,... read all
