Abstract:
Objective: There is a necessity to determine an approach to the development of train traffic control theory at suburban sections, on the basis of the analysis of conventional methods of train traffic control and service situations. Methods: Simulation methods, design theory and train traffic graphing were applied in the study. Results: The possibility of developing the conventional method of commuter service organization on railroads was demonstrated by means of a new data modeling approach, underlying the system of traffic handling capacity of suburban districts. It was shown, that the basis of such a technology is a train schedule modification. It was established that the schemes on selecting schedule modification, compiled in accordance with the standard methodology, may in some cases present the solutions different from conventional. It was concluded that an unexpected result might be achieved in case of simultaneous alteration of both the initial length of suburban zones and initial number of zone trains, that is zone schedule modeling, and elements of traffic schedule within regions, assigned in accordance with its periods and called configurations. The necessity in determination and modeling of configurations was justified by practical demand in traffic volume account of different types of trains at suburban sections. The simplest example of schedule modification and capacity values response to mutual position of trains and schedule elements in configurations was introduced. Practical importance: New theoretical conclusions, obtained as a result of the analysis of suburban areas’ length modeling results, the number of zone suburban trains and their position in configurations along with freight and passenger trains, provide justification of and scientific background for efforts of creating a new methodology of train traffic control at suburban sections. Such a methodology, built on the principles of zone schedule integrated modeling and the introduced traffic schedule configurations, makes it possible to considerably increase the flexibility of commuter service organization, achieve the reduction of passenger time spent on a trip and train expectation with guaranteed execution of the fixed schedule. According to the conducted analysis, the introduced approach may have positive influence on the capacity of suburban sections as well.

Abstract:
This article is written about a new concept of train traffic control. A topic of significant relevance in the field of organisational and safety aspects of train traffic. The existing system of train traffic control is based on the principles of application of field devices railway automation, and depending on their state driver provides movement or stopping of the train. Also on the monitoring panels, which are located in the control center, describes the state of floor devices, by them train dispatcher keeps track only the approximate location of the train. ETCS is based on the idea of continuous monitoring of the transport process using a combination of various technical means, thereby achieving a safe reduction in the transit interval, which means an increase in throughput. The ETCS is based on determining the location of the train, calculating the distance between trains, controlling the maximum permissible speed on the section, calculating the braking curve (depending on the speed over the distance traveled), comparing route data with the technical characteristics of the train. The requirements for ETCS devices are strict parameters of the accuracy of the navigation system: the error in determining the location of the eurobalance should not exceed ± 1 m, and the error of the odometers should not exceed ± 5% of the distance traveled.

Abstract:
The main architectural aspects of metro train traffic control systems are presented. The structure of train traffic control processes is presented with the example of the State Unitary Enterprise “Moscow Metro” and the main tasks that need to be solved to achieve high levels of automation of train traffic control in subways are described. A functional structure of a complex of metro train traffic control systems is presented, covering the levels of organization and planning of train traffic, operational traffic control and direct executive systems. The relationship between objects of automation and remote control of train movement, devices of the operational level and systems of organization and planning of movement are shown. The necessity of re-equipping the metro with means of ensuring transport safety and linking them with traffic control systems such as: means of informing passengers, providing the possibility of promptly informing passengers both during normal operation of the transport system and in case of emergency situations, means of communication “passenger – control center (situation center)” is shown. The latter ensures interaction between passengers and operational personnel of the subway, and if necessary, video surveillance equipment that provides enhanced remote control of the current situation in the interior of rolling stock cars and on platforms. The use of complex systems for controlling the movement of trains in subways increases the efficiency of their use by increasing the throughput and carrying capacity, accurate fulfillment of the traffic schedule and the possibility of its rapid recovery in case of failures. At the same time, traffic safety increases by reducing the likelihood of dangerous train convergence , and also the energy consumption for train traction is reduced due to the choice of energy-optimal train control modes and the optimal distribution of travel time along the line by the criterion of minimum energy consumption for the duration of travel along the tracks

Abstract:
With the increasing use of railway transportation, various methods have been developed for the control and management of train traffic. Train traffic control systems that are currently in use are overwhelmingly centralized systems. In this study, the development of the general structure of railway traffic control techniques is examined, centralized and decentralized control systems are investigated, and an alternative train traffic control system, the Decentralized Train Traffic Management System (DTMS), is suggested. Simulation results on the possible application of the proposed method to a railway line in South-East Turkey are employed to evaluate the performance of the developed system.

Abstract:
Introduction. The authors view methodology disadvantages for the calculating the existent traffic capacity of the single track analytically by defining the limiting space interval. The current calculation methodology does not fully consider the factors influencing the traffic organization. Thus, this method implies that all trains or pairs of trains evenly distribute the traffic capacity does not corresponding to the real situation. Railway sections should have some reserve capacity that provides carriage in condition of actual traffic volume.Materials and methods. The authors proposed a new approach for determining the traffic capacity by the situation modeling through the alternate graph of train traffic and in accordance with various factors effecting the traffic capacity. Moreover, the authors carried out a comparative analysis of the transportation process indicators. They used two variants of the interval control system — automatic and semi-automatic blocking — in irregular traffic conditions.Results. The performed simulation modeling demonstrates that the use of semi-automatic blocking train interval control does not secure the planned train traffic capacity through the single-track designed line in difficult climatic conditions.Discussion and conclusion. The automatic blocking is considered more appropriate for the train interval control system. The mentioned blocking will provide not only the required capacity, but also the possibility of diagnosing the state of the trackway integrity. It is an important issue providing train traffic safety at low temperatures.

Abstract:
With installation of positive train control (PTC) on many U.S. rail corridors, Class I railroads may soon leverage these investments in communications network infrastructure to implement “advanced PTC” systems incorporating moving blocks. Train control with moving blocks can benefit operating strategies that dispatch fleets of multiple trains running at minimum headways. On single-track corridors with passing sidings long enough to hold multiple trains, fleeting may increase the efficiency of train meets, reduce train delay, and yield incremental capacity benefits. Alternative single-track configurations with fleet-length sidings at double the spacing of conventional single-train sidings can facilitate these operating strategies while minimizing additional track infrastructure and associated capital and maintenance costs. To investigate the operational synergies between moving blocks, fleeting, and longer but less frequent sidings, Rail Traffic Controller software is used to simulate and compare the delay performance of train operations on representative rail corridors for different combinations of fleeting strategy, train control system, siding configuration, and freight traffic composition. Operating fleets in conjunction with moving blocks produces the lowest overall train delay in specific cases of low schedule flexibility and heterogeneous traffic. With more efficient meets, moving blocks and/or fleeting primarily benefit low priority trains that typically wait for opposing traffic during train meets. Such incremental line capacity benefits have short-term financial consequences as they allow additional capital investments in double track to be deferred. Knowledge of train delay performance under moving blocks and fleeting will aid railway practitioners evaluating investments in advanced PTC systems and track infrastructure expansion.

Abstract:
These days, automated rail traffic control systems help to lessen the need for human intervention in train traffic management. On the other hand, the various algorithms used by interlocking systems to coordinate the movement of trains belonging to distinct categories result in longer wait times for technological procedures at the station. The possibility of timely routes for trains of multiple categories occurs by employing the method of automatic route preparation by interlocking systems in the organization of the movement of trains of different categories. In interlocking systems, automatic route preparation can be achieved by continuously monitoring train characteristics, train traffic graphs of various train classes, and the condition of equipment involved in the function’s development. Nonetheless, it is predicated on the creation of many models to arrange the specifications of various train classes and train movements inside a single schedule type. In order to prepare the routes ahead of time for the station tracks based on the algorithms for the operation of interlocking systems for various kinds of trains, the paper analyzes the reliance of the traffic composition characteristics.

Abstract:
The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment. At an early stage in the collaboration studies and analysis of important aspects of the traffic controller’s tasks, strategies, decision making, use of information and support systems were undertaken. This research resulted in new control paradigms, from control by exception to control by replanning. By using this paradigm we developed and designed prototype systems and interfaces that could better meet future goals and contribute to more optimal use of infrastructure capacity. Based on this research, a new operational traffic control system called STEG was developed in an iterative and user-centred design process. The system was deployed and tested operatively at a train traffic control centre in Sweden. The following evaluations focused on what happens when STEG is introduced in train traffic controllers’ work places. The evaluation of STEG showed satisfied users with a feeling of active involvement during the design and deployment processes, and gave confirmation that the new control strategies are functioning. STEG was seen as successful and was thereafter developed into MULTI-STEG, intended to be used by several users simultaneously, supporting them to share information in a new way. MULTI-STEG was deployed and tested at another train traffic control centre in Sweden. The following evaluations of MULTI-STEG focused on what happens when several users are involved and how train traffic controllers felt when sharing information, that before would have only been in their own minds, with each other. Some complications occurred due to mistakes in the deployment process, but altogether the evaluation showed positive attitudes towards the new system and MULTI-STEG was perceived as an efficient system for train traffic control. The main results are that STEG and MULTI-STEG can be used as an efficient train traffic control system and the new system can reduce the unnecessary cognitive load currently placed upon traffic controllers in today’s system. Also the deployment process is fundamental to the acceptance or non-acceptance of a new system by users. STEG was developed in a user-centred design process, but it is important that the deployment process is also user-centred.<br>Framtidens system för tågtrafikstyrning kräver nya lösningar och strategier för att bättre kunna möta morgondagens krav och mål inom tågtrafikstyrning. Uppsala universitet och Trafikverket har samarbetat under många år när det gäller tågtrafikstyrning och hur man ska kunna förbättra trafikledarnas styrsystem och arbetsmiljö. I ett tidigt stadium av samarbetet har det gjorts studier och analyser av trafikledarnas uppgifter, strategier, beslutsfattande, användande av tillgänglig information samt deras tekniska stödsystem. Denna forskning resulterade i nya styr-paradigmer; från att arbeta genom att använda styrning genom undantagslösningar till att använda styrning med omplanering. Genom att använda den nya styr-paradigmen utvecklades och designades prototyp-system och gränssnitt som bättre kunde möta framtidens mål och därmed bidra till en mer optimal användning av infrastrukturens kapacitet. Ett nytt operativt tågtrafikstyrningssystem utvecklades och kallades STEG, Styrning av Tåg genom Elektronisk Graf, i en iterativ och användarcentrerad process. Systemet implementerades och testades operativt på en trafikledningscentral i mellersta Sverige. Utvärderingarna som gjordes fokuserade på vad som händer när man introducerade STEG på trafikledarnas arbetsplats. Utvärderingen visade nöjda användare som kände att de fått vara med under både utvecklings- och implementeringsfasen av det nya styrningssystemet, samt att den nya styrprincipen fungerar. STEG var framgångsrikt och har därefter vidareutvecklats till MULTI-STEG som är avsett att användas av flera användare samtidigt och därmed ge trafikledarna en möjlighet att kunna dela information på ett nytt sätt. MULTI-STEG implementerades och testades på en annan trafikledningscentral i norra Sverige. Utvärderingarna fokuserade på vad som händer när flera användare delar information och hur det påverkade deras arbete. En del komplikationer inträffade genom att misstag i implementeringsprocessen gjordes, men sammanfattningsvis så var attityden gentemot det nya systemet positiv och MULTI-STEG ansågs vara ett effektivt system för tågtrafikstyrning. De huvudsakliga resultaten är att STEG och MULTI-STEG kan användas som ett effektivt system för tågtrafikstyrning och att det nya systemet reducerar den onödiga kognitiva belastningen som trafikledarna upplever med dagens befintliga tågtrafiksystem. STEG är utvecklat i en användarcentrerad process, men det krävs även att implementeringsfasen är användarcentrerad för att ett nytt system ska fungera.<br>FTTS

Abstract:
In 2014, the Federal Aviation Administration (FAA) highlighted to the U.S. Senate the need to focus on air traffic control (ATC) training to meet job qualification and attrition rates within the career field. One U.S. Department of Defense military service assists the FAA in providing worldwide ATC services. This service is referred to as the agency throughout this paper to ensure confidentiality. The agency's ATC career field manager echoed the FAA's call for action in his 2014 Strategic/Action Plan. In August 2013, the agency's ATC trainer program was published. As of December 2015, the program had not been evaluated. The purpose of this study was to ascertain if the program facilitated the learning of critical ATC on-the-job training skills. An ad hoc expertise-oriented evaluation was conducted using the lenses of andragogy, experiential learning, and instructional system design (ISD). Purposeful sampling procedures were used to select 20 participants across the subgroups of supervisors, trainers, managers, and training developers from 7 focus sites. The semi-structured interviews queried 4 topical areas derived from Kirkpatrick's 4 levels of evaluation model. Data collected via documents and interviews were analyzed using descriptive, emotion, eclectic, and pattern coding. Key findings indicated that the program was not developed compliant with ISD principles and did not promote adult learning as endorsed by andragogy and experiential learning theory. The implications for positive social change include providing stakeholders with data needed to make evidence-based decisions regarding the current and future state of the program. The evaluation report project can be shared with the FAA, an agency partner, and has the potential to create a platform for improved training practices focusing on optimum and successful adult learning transactions.

Abstract:
Ever wondered how trains arrive and depart on time? Traffic Control systems are there to help control the traffic flow, with many operators monitoring and taking actions when necessary. Operators of the traffic control systems use a keyboard and a mouse to interact. Current user interface and work setup consist of many usability issues that can be improved in order to increase operator’s efficiency and productivity in controlling the traffic. Interviewing users of the system and researching on related topics led to a newly proposed design in interaction, user interface as well as some suggestions for increasing productivity. Gesture-based interaction is introduced and simulated for traffic control systems that tend to improve the operation. Various gestures are designed such as panning, zooming and hovering the map using Leap Motion controller which enables intuitive interaction. These gestures aim to solve identified usability issues discovered during the interview with the user. The project aims to answer the following question: Can gesture-based interaction solve usability issues and establish the intuitive use of the CTC system? Performing exploratory research on this topic involved designing, implementing and testing hand gestures with users. From an ergonomic perspective, body posture and hand position of the operator is examined and suggested to use sit-to-stand workstations in order to reduce pain and discomfort while working. Gesture-based interaction eliminates finding mouse cursor on large screens, it enables fast request of detailed information and also it provides a better overview of the map surroundings. Laboratory tests confirm that gesture-based interaction brings more natural and intuitive use of traffic control systems. There is a big potential for gesture-based interaction to increase usability and bring efficient controlling for operators. It would reduce delays of the train and maintain safe traffic flow.<br>Har du någonsin undrat hur tåg anländer och avgaå i tid? Trafikledningssystem (CTC-system) hjälper till att kontrollera trafikflöet där operatörer övervakar och vidtar åtgärder vid behov. Operatörer av ett trafikledningssystem använder idag ett tangentbord och en mus för att interagera. Det nuvarande användargränssnittet och arbetsinstallationen består av många användbarhetsproblem som kan förbättras för att öka operatörens effektivitet och produktivitet för att kontrollera trafiken. Intervjuer med användare av systemet samt forskning om ämnet ledde till ett nytt föreslag av interaktion, utformning av användargränssnitt samt några förslag för att öka produktiviteten. Den gestbaserade interaktionen som infördes och simulerades för trafikkontrollsystemet tenderar att förbättra funktionen. Olika gester utformades som möjliggör för användaren att panorera, zooma och sväva över kartan. Gesterna implementerades med hjälp av Leap Motion Controller som möjliggör intuitiv interaktion. Dessa gester syftar till att lösa identifierade användbarhetsproblem som upptäcks under intervjuerna med användarna. Syftet med detta arbete var att svara på följande forskningsfråga: Kan gestbaserad interaktion lösa användbarhetsproblem och etablera intuitiv användning av CTC-systemet? Den explorativa forskning som utfördes i detta arbete inkluderade att utforma, genomföra och testa gester med användare. Kroppshållning och handposition för operatorerna undersöktes ur ett ergonomiskt perspektiv och studien föreslår att använda sitt-till-stå arbetsstationer för att minska smärta och obehag under arbetet. Gestbaserad interaktion eliminerar problemet att hitta muspekaren på stora skärmar, vilket gör det enkelt att snabbt hitta detaljerad information och ger även en bättre överblick över kartans omgivning. Laboratorietester bekräftar att gestbaserad interaktion ger mer naturlig och intuitiv användning av trafikledningssystemet. Det finns en stor potential för gestbaserad interaktion för att öka användbarheten och ge en effektiv kontroll för operatörerna. Det skulle minska förseningarna av tåget och upprätthålla ett säkert trafikflöde.

Abstract:
This study focuses on how to define and measure usability in systems used for operational train traffic control. The study is conducted as a project for the Swedish Transport Administration (Trafikverket); the authority that is in charge of the train traffic in Sweden. The train dispatchers are the ones that control the train traffic. Their job includes much decision-making and problem solving and they need to have complete control in each situation. The systems used for train dispatching therefore need to be designed to comply with human cognitive capabilities and skills, to support the users in their work and also to be well adapted to the work tasks of the dispatchers. It was therefore decided to evaluate the usability of the systems by looking at how well they support the train dispatchers when they carry out their work tasks. The analysis of the evaluation focused on finding indicators of bad usability in the interaction between the user and his/her systems. Such problems can affect the user's cognitive capabilities and result in unnecessary cognitive demands. Such issues can affect their abilities to control the systems and their work situation. An analysis of the social support in their work environment and their use of the systems was also conducted. The analysis showed that the systems used today had indicators of both good and bad usability. The usability issues that were found caused cognitive work environment problems for the users. Problems like tunnel vision, short-term memory load, orientation issues and unnecessary cognitive workload was the most distinct ones. To investigate further the specific systems used for traffic control, an evaluation instrument was developed. The purpose of the instrument is to be used by the authority to evaluate the usability in their operational traffic control systems. The evaluation of the systems' usability will give greater insight and knowledge about how it actually affects the user's work situation and cognitive capabilities. Key words: Human-computer interaction, usability, train traffic control, train dispatcher, cognitive work environment problems, psychosocial work environment, techno stress, evaluation instrument USOT.

Abstract:
The railway industry in Ethiopia has been an important way of communication and transportation for a long time. It is a developing sector with many national plans for future investments. However, the current major corridors of Ethio­-Djibouti and Awash­-Weldiya have interoperability issues due to two different signalling systems being used. Thus, this study was undertaken with the objectives of assessing technical interoperability of the Chinese signalling system (CTCS) and the European signalling system (ETCS), identifying a possible technical solution regarding the interoperability issues, and assessing the economic benefits of a harmonized system. Compatibility of the two signalling systems was analyzed particularly with respect tothe technical configurations by thoroughly investigating each system’s features and making interviews and having discussions with professionals who worked with the two systems. In addition, a life cycle cost analysis of the Ethio­Djibouti signalling system was done with data obtained from Ethiopian Railway Corporation and compared with average life cycle costs of ETCS level 1. After analyzing each system, two possible technical solutions were found to achieve interoperability between the two systems used in Ethiopia currently. The first technical solution is upgrading Ethio­Djiboutirailway line from the current CTCS level 0 to CTCS level 2 to be compatible with the new Awash­Weldiya line which will use ETCS level 1. The second technical solution to make the two systems interoperable is to install ERTMS as an overlay on the existing CTCS level 0 as ERTMS is designed as an overlay system that could be installed on top of an existing national infrastructure and vehicles. However, these technical solutions have to be tested in laboratory and onsite with respect to their practical and economical feasibility.<br>Järnvägsindustrin i Etiopien har länge varit viktig för kommunikation och transport. Det är en sektor under utveckling med många nationella planer för framtida investeringar. De nuvarande korridorerna i Ethio­Djibouti och Awash­Weldiya har emellertid interoperabilitetsproblem på grund av två olika signalsystem. Detta examensarbete har analyserat kompatibiliteten för de två signalsystemen särskilt med avseende på de tekniska konfigurationerna genom att noggrant undersöka varje systems funktioner och genom intervjuer och diskussioner med yrkesverksamma somhar arbetat med de två systemen. Dessutom genomfördes en livscykelkostnadsanalys av Ethio­Djibouti signalssystemet med den data som erhölls från Ethiopian Railway Corporation. Efter analys av varje system hittades två möjliga tekniska lösningar för att uppnå interoperabilitet mellan de två systemen som används i Etiopien för närvarande. Den första tekniska lösningen är att uppgradera Ethio­Djiboutis järnvägslinje från nuvarande CTCS nivå 0 till CTCS nivå 2 för att vara kompatibel med den nya Awash­Weldiya­linjen som kommer att använda ETCS nivå 1. Den andra tekniska lösningen för att göra de två systemen interoperabla är att installera ERTMS som ett överlägg på det befintliga CTCS­0 signalsystemet, eftersom ERTMS är utformat som ett överläggssystem som kan installeras ovanpå en befintlig nationell infrastruktur. Dessa tekniska lösningar måste dock testas i laboratorium och i fält med avseende på deras praktiska och ekonomiska genomförbarhet.

Abstract:
Train traffic control is a complex task in a dynamic environment. Different actors have to cooperate to meet strong requirements regarding safety, punctuality, capacity utilization, energy consumption, and more. The GMOC model has been developed and utilized in a number of studies in several different areas. This thesis describes GMOC and uses train traffic control as the application area for evaluating its utility. The GMOC model has its origin in control theory and relates to concepts of dynamic decision making. Human operators in complex, dynamic control environments must have clear goals, reflecting states to reach or to keep a system in. Mental models contain the operator’s knowledge about the task, the process, and the control environment. Systems have to provide observability, means for the operator to observe the system’s states and dynamics, and controllability, allowing the operators to influence the system’s states. GMOC allows us to constructively describe complex environments, focusing on all relevant parts. It can be utilized in user-centred system design to analyse existing systems, and design and evaluate future control systems. Our application of GMOC shows that automation providing clear observability and sufficient controllability is seen as transparent and most helpful. GMOC also helps us to argue for visualization that rather displays the whole complexity of a process than tries to hide it. Our studies in train traffic control show that GMOC is useful to analyse complex work situations. We identified the need to introduce a new control strategy improving the traffic plan by supporting planning ahead. Using GMOC, we designed STEG, an interface implementing this strategy. Improvements that have been done to observability helped the operators to develop more adequate mental models, reducing use of cognitive capacity but increasing precision of the operative traffic plans. In order to improve the traffic controllers’ controllability, one needs to introduce and share a real-time traffic plan, and provide the train drivers with up-to-date information on the surrounding traffic. Our studies indicate that driver advisory systems, including such information, reduce the need for traffic re-planning, improve energy consumption, and increase quality and capacity of train traffic.<br>KAJT<br>FTTS

Abstract:
Purpose - This bachelor thesis compares high-speed rail (HSR) transport with air transport. The investigation considers physical fundamentals, energy consumption, environmental impact, infrastructure and investment, market situations, passenger's selection criteria to choose transportation options, and overall economics. --- Methodology - The thesis combines an investigation of physical principles with a literature review. --- Findings - Steel wheels on steel rails show by far less rolling resistance to support the train's weight than drag due to lift (induced drag) to support the aircraft's weight. This leads to less energy consumption. HSR trains use electricity from an overhead line. Hence, the environmental impact of HSR also depends much on how the electricity is produced. Airplanes only need an air traffic control environment to connect airports. In contrast, HSR needs infrastructure to connect stations. The amount of necessary infrastructure depends on the geological conditions. For example, crossing mountains means high investment. Longer passages over water are infeasible for HSR. High-speed rail is superior to air transport when connecting megacities because the trains have higher transport capacity, offer higher service frequencies and mission reliability, shorter total travel time, shorter access time to stations, shorter unproductive waiting time in stations and potentially lower travel costs. HSR is a strong competitor to airline services and has replaced some short range flights. A comparison of HSR in different world regions shows differences in the market situation and in passenger's selection criteria for transportation options. --- Research limitations - The potential of high-speed rail was investigated mainly on busy routes with high service frequencies. A comprehensive network comparison between high-speed trains and airplanes was not done and could lead to somewhat different results. --- Practical implications - The report tries to contribute arguments to the discussion about alternatives to air travel. --- Social implications - With more knowledge people can make an educated choice between transport options, can vote with their feet, and can take a firm position in the public discussion. --- Originality/value - A general comparison of HSR and air transport from physical fundamentals to economics seemed to be missing.

Abstract:
The increasing demand for transport and the shift from road to rail cause the congestion in railway infrastructure, with low quality of service. To reduce congestion and enhance the infrastructure capacity some solution, such as planning and constructing of new infrastructure or upgrading the existing infrastructure, are costly and time consuming. Therefore, it is necessary to manage capacity of infrastructure in efficient way by enabling trains to run with shorter distance from each other. In this context, the importance of Control Command and Signalling systems (CCSs) and their role to provide a service with short headway is clear. This thesis studies the effectiveness of the European Railway Traffic Management System/European Train Control System Level 3 Full Moving Block (ERTMS/ETCS L3 FMB). The combination of two methods allows achieving this goal: 1) analytical method provided by International Union of Railways (UIC) in leaflet Code 406, that is called compression method to evaluate infrastructure occupation, considering blocking time sequences and related variables (to calculate minimum headway) for each CCS configuration. 2) Data extracted from RailSys simulation tool (minimum headway) for each CCS configuration to calculate Capacity Consumption (CC) applying the compression method. In this way, it is possible to compare the effectives of different CCSs against and discuss about results of the two different methods. To perform this evaluation, the selected case study was the Northbound of city line in Stockholm (Citybanan) in peak period. The line is a double track line dedicated to commuter trains with homogeneous traffic. The results confirm that: • ERTMS/ETCS Level 3 Full Moving Block provide shorter headway and capacity consumption compared to other signalling systems based on fixed block technology; • In ERTMS/ETCS Level 2, the location of indication points and braking curves significantly affect the infrastructure’s capacity. ETCS L2 offers shorter headway and lower capacity consumption comparing to legacy system.

Abstract:
This article focuses on analyzing the systems and methods used for the interval regulation of train movement on “Rail Baltica” line in “Lithuanian Railways”. The method discussed in the article can be viewed as a combination of several management automation solutions and it is based on the implementation of the European Railway Traffic Management System (ERTMS). As it is known, the ERTMS provides an interoperable European railway network. The primary objective is to improve the quality of train traffic and to make railway transport safer and more comfortable. In order to ensure new traffic prevision for Lithuanian Railways, new interval regulation methods and traction calculations must be used. This developed method is more useful than the previous methods as it allows to shape an efficiently automated and optimized scheduling process as well as to improve line capacity and efficiency. This paper proposes the development of a moving block train control system. The calculations were made using the intervals between trains. The interval and block-section borders are not fixed by traffic signs or traffic-lights. Instead, they move after the train in the front, creating a flexible interval regulation system. The results showed that the implementation of the method had a positive impact on the operators’ performance and allowed to reduce energy consumption and to increase the speeds of train movement. The paper also presents a statistical figure portraying railway accidents and railway operation accident reports before and after the implementation of the ERTMS. The results of the analysis showed that the implementation of the European Train Traffic control systems and the interval regulation of train movement method will provide high throughput and carrying capacity, traffic safety and also increase the productivity of operation procedures.
