Controversial questions of transport policy
Drahotský, Ivo
2010 - anglický
The report deals with the current situation in the sphere of transportation and the connection
between transportation and the economic sector. There is an array of problems related to transportation, many of them, however, come more under the political sphere. On one hand we are forced to solve traffic jams, the ecological aspects of transportation, etc., on the other hand these activities usually mean additional costs for the users. Transportation also generates substantial funds for public finance which
would fall should transportation be limited. There is of course the effort to balance the potential fall by funds that are obtained in other ways. Therefore, the question is whether the accountable authorities will be able to inform the users that they will pay more but get less.

Function integrated track system
Hohnecker, Eberhard
2010 - anglický
The paper discusses a function integrated track system that focuses on the reduction of acoustic
emissions from railway lines. It is shown that the combination of an embedded rail system (ERS), a sound
absorbing track surface, and an integrated mini sound barrier has significant acoustic advantages
compared to a standard ballast superstructure. The acoustic advantages of an embedded rail system are
particularly pronounced in the case of railway bridges. Finally, it is shown that an ERS with track
integrated vibration sensors may be used as an early warning system and for monitoring the structural health of the railway infrastructure.

Enhancing the energy efficiency of diesel multiple units with hydrodynamic power transmission
Kache, Martin; Steglich, Uwe
2010 - anglický
The authors discuss the impact of several measures to save and regain energy during the operation
of diesel multiple units (dmu) on regional and local railway lines. The problem of recuperating and storing kinetic energy on vehicles with hydrodynamic power transmissions as well as a strategy of using the waste heat of the diesel engine are examined. A model to simulate (hybrid) diesel hydraulic multiple units is presented, taking into account the influences of track and driver behaviour. The simulation results provided show a significant fuel saving potential for rail vehicles with hybrid drive trains.

Utilization of polycomponent composites in automobile transport
Krmela, Jan; Pešlová, Františka; Tomanová, Vladimíra
2010 - anglický
Polycomponent composite materials for automobile transport are used in interior of automobiles
and namely for tyre manufacturing. The tyres are essential elements into interactions between vehicles and roads which secured of force transmission with ability of damping of road irregularity etc. Therefore it expect from these materials with theirs excellent material parameters that will be able to good securing
of observance of right function with respect to working requirements of automobile and high tyre life. The contribution deals with complex composite – tyre for its characteristic specific deformation properties. These properties are determined of construction – geometry and placement of reinforcements and also tyre materials. The computational modelling of strain-stress states of selected composite assisting to solution of right selection of optimum geometry and placing reinforcing long-filaments – cords. The authors used for computational modelling the Finite Element Method program ANSYS. The orientation is namely on materials parameters of rubber matrix and steel-cord reinforcement, which are applied into tyre casing for passenger vehicles.

Small aircraft transportation system in Poland – idea and model assumptions
Marciszewska, Elžbieta; Bergel, Izabella
2010 - anglický
The paper presents the idea of small aircraft transportation system in Poland based on research
being done within a grant of Institute of Aviation along with Warsaw School of Economics and Warsaw
Institute of Technology. The final aim of this system is to provide a fast means of transport to all Polish regions, especially the provision of business trips to/from any region in Poland within one day at the cost comparable to travelling by car. Within the research on SATS there was a series of investigation on intra-regional mobility, passenger flows estimation based on income distribution, time value and intraregional
mobility statistical database. Direct research (questionnaire) involved three regions, 900 respondents (households and companies). Data gathered on intra-regional mobility is a basis
for modelling the demand for SATS services, including formulation of transportation task, selection of aircraft and system workings. In the final phase of research an attempt will be made at working out a comprehensive idea of SATS workings in Poland along with flight and fleet management system, flight scheduling and service marketing. It is also assumed that SATS Data Collecting and Management System (System Wide Information Management) will be established within SESAR programme by 2020. During the research on SATS in Poland research and studies carried out within EPATS (European Personal Air Transportation System) project were used. These were a part of the Sixth Framework Programme of the EU.

Innovative approach to determining railway line capacity
Mojžíš, Vlastislav; Molková, Tatiana; Bulíček, Josef
2010 - anglický
The contribution deals with critical assessment of used analytical and graphic-analytical methods
for determining the lines capacity and of problems connected to the capacity formulation. Negative
outcomes from executed case studies force us to investigate new approaches, which would result in more accurate capacity determination. Simulation models appear to be an appropriate tool allowing
the investigation of the capacity of transport infrastructure in the interaction with the range of traffic. In case of incongruity between the transport infrastructure and the range of traffic operation, the implementation of various arrangements including the economical assessment can be simulated by means of scenarios. At the end of the paper a short list of the experience with the application of simulation modelling on particular lines in the Czech Republic is presented.

Automatic train route setting in Czech Republic
Polach, Vlastimil; Růžička, Martin
2010 - anglický
The operation of railway traffic from a single dispatching control centre ensures high quality
of traffic management. Even better traffic control could be achieved through the automation
of the dispatchers’ routine work. It saves dispatchers´ time which he can be devoted to solving conflicts caused by delayed trains.
The process of planning the traffic and the execution of this plan are two independent activities which have to be done simultaneously. The dispatcher of the remote controlled lines has not just to optimize the railway traffic, he has to care for the properly train route setting as well. The new system of automatic train route setting should help him by doing much work on above mentioned activities for him. System that fulfils these requirements is automatic train route setting system. System or train dispatcher just decides how to handle the conflict situation and the function of automatic train route setting will execute the command at the proper time. This trend can be also seen in other countries. Very helpful for dispatchers who control the railway traffic is the graphic timetable. There is a common used application called GTN on Czech railways which is supplied together with the electronic interlocking from the AZD Praha. This application shows the actual and expected graphic
timetable in the most appropriate form for dispatcher and moreover provides many other support functions. New designed function of the graphic train route editor enables precising the predicted timetable and consequently gaining the most probable prediction in the next moments. Given that GTN knows the actual timetable, dispose of data of trains and knows the exact train location in real time, the GTN is nowadays a powerful tool for decision support for traffic control staff. Therefore, GTN is an essential part of the system of automatic train route setting which is now being developed. Using the existing electronic interlocking, their remote control and the GTN application seems to be the easiest way how to implement automatic train route setting system on the infrastructure of the Czech railways.
