Enhancing the energy efficiency of diesel multiple units with hydrodynamic power transmission
Kache, Martin; Steglich, Uwe
2010 - English
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.

Small aircraft transportation system in Poland – idea and model assumptions
Marciszewska, Elžbieta; Bergel, Izabella
2010 - English
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 - English
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 - English
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.

Provazníková, Romana; Petr, Pavel
2010 - English
The Goal of this contribution is to demonstrate an illustrative example of genetic
programming application in the area of regional administrations financing. The principle of
genetic programming is used for the establishing of the analytical function for the calculation
of the share each individual municipality has in the national shared taxes revenues in the
Czech Republic. This approach is confronted with the existing municipal financing principle
issuing from the effective act on Tax Assignment to sub-national Government Level.

Regional railway transport funding in conditions of the Czech Republic and in the Pilsen region
Benediktová, Marcela; Chlaň, Alexander
2010 - English
Present situation in financing of regional railway transport does not allow sustainable development of transport services in a region and also often leads to further worsening of situation in rolling stock financing. This paper describes basic problems related to financing of regional transport services from
regional budgets. Stability of regional railway transport financing in the future provides the resolution of government of the Czech Republic No. 1132/2009 from the 31st August 2009, for the renewal of rolling stock will be possible to get grants from the Regional operational program (ROP). Regional
authorities have to decide how to prepare the long-term contract concerning the public service obligation. The question is how to choose the operator of regional trains and how to get the highest quality of provided services from amount incurred.

Organizational level of public transport controlling in the public transport system
Břečka, Patrik; Kopecký, František; Kohl, Jiří
2010 - English
Controlling of public transport is a newly developed term just in connection with the IDS development. It is and it will be a direct support of the functioning transport system in the region, namely the support of interconnections of individual lines and services of individual transport operators. Transport technologists who have introduced this term, however, use it to cover all what is connected with the development of public transport in regions. This means a plan of the lines, awarding of contracts to transport operators, creation, monitoring of JŘ adherence, payments in the public transport, monitoring of provable losses, etc., but also the planning and the development of transport routes, transport terminals and interchange junctions. This very general term is not suitable from the viewpoint of creation of information and telematic support. This has already been highlighted by the solvers of the project entitled "Plans of ITS development in the link to the performance of state administration and local government",
and therefore they have proposed a necessity of division of this term from the viewpoint of the existing, but especially the future organisation levels in the field of planning, actual organisation and control of public transport in regions. This is given by the presupposed model of activities of a coordinator of public transport.
