This paper is focused on a very current issue of software timetabling, concretely on development and stabilization of the railway infrastructure data base, used for railway timetabling and microsimulation of railway traffic. An infrastructure dataset usually consists of a sequence of so-called “transport points”, each of which has a specified mileage position. Each element of the infrastructure, i.e. each transport point, must be uniquely and uniquely identified too. The purpose is to create a logical structure of marking and design of the arrangement architecture of individual infrastructure elements. This is a completely new approach, because in the Czech environment it is not possible to use the marking system used by the infrastructure manager (Správa železnic), because the development of this marking was gradual and does not meet the current requirements for a unified marking logic. The goal is to design a system architecture that allows the creation of large networks and allows them to be interconnected, without the risk of duplication.

Cílem studie je přinést alternativní pohled na řešení a koncepci dopravy v Plzeňském kraji. V rámci řešené studie tak řešitelé nahlédli na současnou koncepci veřejné dopravy v Plzeňském kraji z jiného úhlu pohledu a předestřeli, jakým obecným způsobem lze jinak než dnes přistupovat k organizaci veřejné dopravy jak z pohledu samotného provozu (jízdní řády, návaznosti, četnost spojení), tak i z pohledu tarifu. Řešená studie tak představuje diskusní materiál, který vychází z analýzy současné situace a přes charakteristiku přepravních vztahů v území vede k alternativním návrhům řešení v oblasti organizace železniční a autobusové dopravy a možnostem tarifního řešení.

A netgraph is a graphical representation of a periodic timetable concept for given spatial or modal scope. It adds a third dimension to the network plan - time. Despite no strictly prescribed rules, a common practice notation has been settled over time. The authors propose an extension of a netgraph for planning of periodic railway capacity and operation, including related notation rules.

The Smart Cities concept needs, among others, efficient and sustainable public transport system, as a precondition for implementation of smart mobility. Besides well-researched problems, an efficient long-term rail infrastructure development is also crucial for improvement of transport system performance and quality of life. In this paper, a system-oriented approach for coordinated rail infrastructure planning is proposed. Thereafter, the approach is briefly demonstrated on the example of Prague rail hub area. The conclusion is that not only advanced traffic management and signaling systems, but also efficient service concept, which includes synergistic effect between various segments of rail transport, iteratively coordinated with capacity and land use planning, can substantially increase the rail system efficiency and usable network capacity.

Cílem dokumentu je tedy uspokojovat přepravní poptávku s minimálními dopady na veřejné zdraví, životní prostředí a klimatické změny. Schopnost uspokojovat přepravní poptávku nesmí být omezujícím faktorem hospodářského růstu. Na druhou stranu organizace výroby a distribuce musí zohledňovat cenu dopravy včetně externích nákladů a musí přicházet s logistickými řešeními, která omezují potřebu věci přepravovat, pokud to není nezbytně nutné. Jde tedy o to, aby ekonomický růst probíhal rychleji než celkové přepravní potřeby.

Regulation (EU) No 1315/2013 defines actual scope of core and comprehensive TEN-T network, including both networks for railway freight transport. For the core network, possibility to operate 740 m long freight trains is required. The aim of this paper is to analyse availability of appropriate overtaking tracks for 740 m long freight trains. Due to ETCS braking curves and odometry, such trains, after ETCS implementation, will require 780-800 m long overtaking tracks. For practical reasons (e.g. bypass lines), whole Czech railway TEN-T network is analysed. The overtaking track, whose occupation means influence on scheduled traffic or threat to boarding passengers, are excluded. The data was collected from station schemes from Collection of Official Requisites for 2015/16 Timetable, issued by SŽDC, Czech state Infrastructure Manager. Most of appropriate tracks are over 800 m long, but their density in the network and in particular directions varies considerably. For freight traffic, gradient of the line is important, so there are marked significant peaks for particular lines as well. Czech TEN-T lines are further segmented on the basis of number of tracks and their traffic character. As a conclusion, for long-term development of Czech TEN-T lines, targeted investment is recommended not only for passenger railway, but also for freight railway. An attractive capacity offer for railway undertakings, which can stimulate freight traffic on European Rail freight corridors, can be represented by network-bound periodic freight train paths with suitable long overtaking tracks outside bottlenecks. After the overtaking by passenger trains, a freight train should run without stop through large node station or a bottleneck area. Before the sections with high gradients, coupling of additional locomotives should be connected with the overtaking process. Next suitable overtaking tracks should be available behind every significant peak of the line.

Cílem tohoto výzkumného projektu je zformulovat metodiku optimalizace využití tratí s vyčerpanou kapacitou, tedy navrhnout postup optimální vzájemné interakce parametrů infrastruktury a vozidel s ohledem na dopady na požadavky železničního provozu směrem k objednatelům závazků veřejné služby a konečným zákazníkům. K dosažení výše uvedeného cíle slouží analytická část a metodika. Analytická část sestává z analýzy legislativy z pohledu přidělování kapacity dráhy a operativního řízení provozu, sběr požadavků objednatelů, případně dopravců, na kapacitu a analýza parametrů zejména nákladních vlaků tak, aby mohly být konstruovány katalogové trasy vyhovující většině dopravců. Byla rovněž shromážděna relevantní dobrá praxe z vyspělých evropských zemí. Vzhledem k roli objednatelů v ČR je přidána rovněž pasáž vysvětlující ITJŘ a segmentaci nabídky v osobní dopravě, neboť obojí úzce souvisí s využitím kapacity.

The aim of this paper is a comparison of different quantitative methods for determination of bottlenecks on a railway network with periodic timetable. The railway capacity consumption increases not only with number of trains per time unit, but also with their heterogeneity, i.e. difference between runtimes of following trains in the particular section. These two factors should be quantified, so that lines and sections with “more“ and “less“ exhausted capacity can be clearly distinguished. All presented methods will be verified on the example of the busiest sections of Czech railway network. Finally, difference of rankings of the sections will be discussed.

Passenger information systems in the modern concept of transport as a service play key role in creating the passengers feeling about the service. Passengers accustomed to smart telematics services in all branches of service expect that especially in the highly structured, managed and monitored public transport the information system will provide just the information needed and just in the time needed. However, for several reasons these expectations are not met with today's realities. This article aims to describe the requirements and prerequisites for information systems in public transport from the perspective of the transportation service provided rather than from the traditional technically descriptive point of view. Interaction with the passenger carrier at the stage before and after the journey is very different depending on the product used (reservation conditions, tariffs, local laws and regulations etc.) and is rather subject to the carrier's business strategy. This article focuses therefore particularly on information provided just before and during the own journey on the station / terminal, on the vehicles and during the journey itself, guiding the passenger as a customer through the rather complicated and mostly unstaffed system whether using radio systems, visual boards, providing real-time applications and open data or using direct messaging. And this not only during normal operation, but especially during service disturbance.

This paper deals with public transport service design and its assessment. Most approaches in this field are currently based on calculating time savings caused by designed improvement in the public transport supply. These techniques use as an input constant supply in the form of origin-destination (OD) passenger flow matrix. However, in fact, the passengers change their decisions on the basis of the new public transport supply. So they can change their destination, mode of transport or route in the public transport network. The macroscopic transport models can record, describe and forecast these changes. This paper presents new assessment technique based on the macroscopic transport modelling. Several accessibility indicators are derived from such model and the assessment uses changes in these indicators to evaluate particular public transport service design. As a numerical example, assessment of the new public transport service design in Jindřichův Hradec is presented.

High quality of operational concepts in railway transport represents one of the basic premises of functional public transport system and public transport services. In this area the systematic timetable engineering plays an important role. Advanced timetable engineering brings a strong contribution for an effective use of infrastructure capacity. This effectiveness is particularly fundamental by investment-consuming railway infrastructure.
