Full textAbstract:
Impacts analysis of train operation on passenger flow in metro stations is an important and fundamental require-ment to improve the operational efficiency and ensure passengers a high level of service. This study aims at large metro sta-tions where thousands of passengers are moving, boarding or alighting and the complicated interactions among passengers and between passengers and other entities like stairways or trains take place all the time. A multi-agent-based approach is developed from the investigation of movement characteristics of passengers to meet the above requirement and deal with such interactions. The simulation scenarios considering the various conditions of train operations are performed in the case studies of a metro station in Beijing (China) to prove the feasibility of the proposed approach, which is useful to for-mulate and evaluate the operation schemes of trains

Full textAbstract:
Based on simulations of passenger transports of two representative types of metro trains in China, this study analyzes efficiencies of energy consumption and passenger transport of a metro train in the effect of its target speed, formation scale (FS) (i.e., length and mass of the formation), relative traction capacity (RTC) (i.e., ratio of the motoring cars to all its cars), and so forth. It is found that increasing energy cost efficiency of a metro train with decreasing its target speed is evidently accelerated with reducing its RTC below 0.50 at the expense of obviously lowering its passenger transport efficiency. Moreover, if the passenger capacity of the train is sufficiently utilized, increasing its FS for the same RTC is easy to have its passenger transport efficiency improved significantly even for a meanwhile much decreased target speed with consuming energy less intensively. Therefore, metro trains in peak hours may take comparatively big FSs, relatively high target speeds, and RTCs over 0.50 to meet usually urgent and large-scale travel demands in such time. In contrast, trains in nonpeak hours ought to have small FSs, relatively low target speeds, and RTCs smaller than 0.50 for mainly avoiding energy waste.

The world is advancing every day in terms of technology, making lives easier. The world is progressing with the modernization of technology exponentially. Each technology is gradually becoming automated, as technology used in transport. Transport is an absolute necessity for people. Thus, in the field of transport, there is also a constant improvement. Previously, trains were operated manually with the help of a driver. The problems encountered with the use of manually operated metro trains were inefficient in terms of the characteristics, such as speed, delay, etc. In addition, a single mistake made by the driver can lead to serious consequences. The main problem is that a manually operated metro train is out of control over time, which negatively affects the railway network management system. To solve this problem, the need for drivers is being eliminated by the concept of driverless metro trains. The advantages of an automated metro system are that the safety of passengers is under control, and the energy consumption is reduced, which improves its operation.

This paper establishes a Finite Element (FE) model of a rigid barrier impact of a single vehicle constructed from carbon steel, stainless steel, and aluminum alloy, which are three typical materials used in metro vehicle car body structures. The different responses of the three materials during the collision are compared. According to the energy absorption, velocity, deformation and collision force flow characteristics of each vehicle, the relationship between the energy absorption ratio of the vehicle body and the energy absorption ratio of its key components is proposed. Based on the collision force flow distribution proportion of each component, the causes of the key components’ deformation are analysed in detail. The internal relationship between the deformation, energy absorption and impact force of the key components involved in a car body collision is elucidated. By determining the characteristic parameters describing the vehicle’s dynamic stiffness, a metro vehicle frontal impact model using lumped parameters is established that provides a simple and efficient conceptual design method for railway train safety design. These research results can be used to guide the design of railway trains for structural crashworthiness.

Full textAbstract:
Rapid transit systems or metros are a popular choice for high-capacity public transport in urban areas due to several advantages including safety, dependability, speed, cost, and lower risk of accidents. Existing studies on metros have not considered appropriate holistic urban transport models and integrated use of cutting-edge technologies. This paper proposes a comprehensive approach toward large-scale and faster prediction of metro system characteristics by employing the integration of four leading-edge technologies: big data, deep learning, in-memory computing, and Graphics Processing Units (GPUs). Using London Metro as a case study, and the Rolling Origin and Destination Survey (RODS) (real) dataset, we predict the number of passengers for six time intervals (a) using various access transport modes to reach the train stations (buses, walking, etc.); (b) using various egress modes to travel from the metro station to their next points of interest (PoIs); (c) traveling between different origin-destination (OD) pairs of stations; and (d) against the distance between the OD stations. The prediction allows better spatiotemporal planning of the whole urban transport system, including the metro subsystem, and its various access and egress modes. The paper contributes novel deep learning models, algorithms, implementation, analytics methodology, and software tool for analysis of metro systems.

Full textAbstract:
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

Reliving the stress of the urban public transport, the metro system is greatly superior to other transport methods on the load, energy consumption, mean drive speed, arrival on time and comfortableness. The passengers comfortable is the important part for developing the train operation strategies. For optimization of the energy, time saving and the passengers comfortableness during operation of the train, the proper objective function is designed. The train operation strategy for meeting the inter-stop passengers comfortableness at the curves was developed and the energy and time savings of the section were combined, and the optimization operation plan for the whole line was designed, to better meet the metro train operation.

Full textAbstract:
A major problem connected with planning the organization of trains in metros is the optimization of the scheme of movement, which determines the routing and the number of trains. In this paper, a combined simulation-optimization model including four steps is proposed. In the first step, the train movement has been simulated in order to study the interval between the trains according to the incoming passenger flows at the stations. The simulation model was elaborated using the ARENA software. The results were validated through experimental observations. Using the results obtained from simulations in the second step the correlation between the observed parameters - the incoming passengers and the interval between trains - has been studied. Recent research has established a non-linear relationship between the interval of movement, incoming passengers at the station and passengers on the platform. The third step defines the variant schemes of transportation. The fourth step presents the optimal choice of transportation of trains in metros based on linear optimization model. The model uses the regression obtained in the second step. The practicability of the combined simulation-optimization model is demonstrated through the case study of Sofia’s metro in two peak periods – morning and evening. The model results and the real situation have been compared. It was found that the model results are similar to the real data for the morning peak period but for the evening peak period it is necessary to increase the number of trains.

Full textAbstract:
Sydney Metro is the biggest project of Australia’s public transport, which was designed to provide passengers with more trains and faster services. This project was first implemented in 2017 and is planned to be completed in 2024. As presented, the project is currently in the construction stage located on the ground stations of the Sydney Trains Bankstown line (T3). Based on this stage, several construction activities will generate air pollutants, which will affect the air quality around construction areas. Moreover, it might cause health problems to people around there and also the passengers who usually take the train on the T3 line. However, there is no specific data for air quality inside the train that may be affected by the construction from each area. Therefore, the aim of this study is to investigate the air quality inside the train carriage of all related stations from the T3 line. A sampling campaign was conducted over 3 months to analyze particulate matter (PM) concentration, the main indoor pollutants including formaldehyde (HCHO) and total volatile organic compounds (TVOC). The results of the T3 line were analyzed and compared to Airport & South line (T8) that were not affected by the project’s construction. The results of this study indicate that Sydney Metro construction activities insignificantly affected the air quality inside the train. Average PM2.5 and PM10 inside the train of T3 line in the daytime were slightly higher than in the nighttime. The differences in PM2.5 and PM10 concentrations from these periods were around 6.8 μg/m3 and 12.1 μg/m3, respectively. The PM concentrations inside the train from the T3 line were slightly higher than the T8 line. However, these concentrations were still lower than those recommended by the national air quality standards. For HCHO and TVOC, the average HCHO and TVOC concentrations were less than the recommendation criteria.

Full textAbstract:
Transport is a main source of pollutants in cities, where air quality is a major concern. New transport technologies, such as electric vehicles, and public transport modalities, such as urban railways, have arisen as solutions to this important problem. One of the main difficulties for the adoption of electric vehicles by consumers is the scarcity of a suitable charging infrastructure. The use of the railway power supplies to charge electric vehicle batteries could facilitate the deployment of charging infrastructure in cities. It would reduce the cost because of the use of an existing installation. Furthermore, electric vehicles can use braking energy from trains that was previously wasted in rheostats. This paper presents the results of a collaboration between research teams from University of Rome Sapienza and Comillas Pontifical University. In this work, two real European cases are studied: an Italian metro line and a Spanish metro line. The energy performance of these metro lines and their capacity to charge electric vehicles have been studied by means of detailed simulation tools. Their results have shown that the use of regenerated energy is 98% for short interval of trains in both cases. However, the use of regenerated energy decreases as the train intervals grow. In a daily operation, an important amount of regenerated energy is wasted in the Italian and Spanish case. Using this energy, a significant number of electric vehicles could be charged every day.

Full textAbstract:
This chapter focuses on India’s public transport system. If cities are democratic laboratories that nurture free and equal motion, then India fails the test every day. In Mumbai, for example, up to sixteen people can find themselves packed into a one-square-metre space inside a carriage during peak hours as Indian Railways fails to provide enough trains and coaches to the financial capital’s arterial rail network. Travelling like animals, risking their lives for livelihood, has been the lot of Mumbai’s daily commuters for as long as they can remember. Away from the cities, where 70 per cent of India lives, the picture is even bleaker, with virtually no state-run public transport system—buses or trains. The daily indignities and inconveniences of travelling prevents citizens from freely accessing goods, services, and social networks that are key to the pursuit of their chosen life strategies. By hindering everyday mobility, hazardous and insufficient transport options have the anti-democratic effect of perpetuating social inequities and dispersing communities into isolated silos that prevent collective assembly, deliberation, and action. Other than dilapidated or non-existent public transport systems, elitist policies, and poor government oversight hinder movement—and democracy—in various other ways.

Full textAbstract:
Issues regarding environment sustainability and energy saving have been receiving concerns in worldwide railway society though railway system have been recognized as a transport mode of less environmental impact. Energy saving via train operation and regulation would be a cost-effective way and becomes a requirement while performing train operation and regulation. Automatic Train Regulation (ATR) plays an important role of maintaining the service quality of metro. However, designing ATR is a large scale optimization problem with high nonlinearity, heavy constraints, and stochastic characteristics. Considering issues regarding energy saving in the ATR design further complicates the problem. A metro traffic model which accounts for energy consumption is investigated in this paper. Thereby, Dual Heuristic dynamic Programming (DHP) technique is employed to design an optimal ATR with energy saving for metro line. Simulation tests of the ATR design were carried out with field data. Results show that better traffic regulation with less energy consumption is attainable through coasting and dwell time control.

Full textAbstract:
Nowadays there is an evident concern regarding the efficiency and sustainability of the transport sector due to both the threat of climate change and the current financial crisis. This concern explains the growth of railways over the last years as they present an inherent efficiency compared to other transport means. However, in order to further expand their role, it is necessary to optimise their energy consumption so as to increase their competitiveness. Improving railways energy efficiency requires both reliable data and modelling tools that will allow the study of different variables and alternatives. With this need in mind, this paper presents the development of consumption models based on neural networks that calculate the energy consumption of electric trains. These networks have been trained based on an extensive set of consumption data measured in line 1 of the Valencia Metro Network. Once trained, the neural networks provide a reliable estimation of the vehicles consumption along a specific route when fed with input data such as train speed, acceleration or track longitudinal slope. These networks represent a useful modelling tool that may allow a deeper study of railway lines in terms of energy expenditure with the objective of reducing the costs and environmental impact associated to railways.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3273

Full textAbstract:
Magnetic levitation (maglev) is a highly advanced technology which provides, through magnetic forces, contactless movement with no wear and friction and, hence, improved efficiency, followed by reduced operational costs. It can be used in many fields, from wind turbines to nuclear energy and elevators, among others. Maglev trains, which use magnetic levitation, guidance and propulsion systems, with no wheels, axles and transmission, are one of the most important application of the maglev concept, and represents the first fundamental innovation of rail technology since the launch of the railroad era. Due to its functional features, which replaces mechanical components by a wear free concept, maglev is able to overcome some of the technical restrictions of steel-wheel on rail (SWR) technology, running smoother and somewhat quieter than wheeled systems, with the potential for higher speeds, acceleration & braking rates and unaffected by weather, which ultimately makes it attractive for both high speed intercity and low speed urban transport applications. From a technical perspective, maglev transport might rely on basically 3 technological concepts: i) electromanetic suspension (EMS), based on the attraction effect of electromagnets on the vehicle body, that are attracted to the iron reactive rails (with small gaps and an unstable process that requires a refined control system); ii) Electrodynamic Levitation (EDL), which levitates the train with repulsive forces generated from the induced currents, resulted from the temporal variation of a magnetic field in the conductive guide ways and iii) Superconducting Levitation (SML), based on the so called Meissner Effect of superconductor materials. Each of these technologies present distinct maturity and specific technical features, in terms of complexity, performance and costs, and the one that best fits will depend on the required operational features of a maglev system (mainly speed). A short distance maglev shuttle first operated commercially for 11 years (1984 to 1995) connecting Birmingham (UK) airport to the the city train station. Then, high-speed full size prototype maglev systems have been demonstrated in Japan (EDL) (552 kph - 343 mph), and Germany (EMS) (450 kph - 280 mph). In 2004, China has launched a commercial high speed service (based on the German EMS technology), connecting the Pudong International Airport to the outskirts of the city of Shanghai. Japan has launched a low speed (up to 100 kph - 62.5 mph) commercial urban EMS maglev service (LIMINO, in 2005), followed by Korea (Incheon, in 2016) and China (Changsha, in 2016). Moreover, Japan is working on the high speed Maglev concept, with the so called Chuo Shinkansen Project, to connect Tokio to Nagoya, in 2027, with top speeds of 500 kph (310 mph). China is also working on a high speed maglev concept (600 kph - 375 mph), supported on EMS Maglev technology. Urban Maglev concept seeks to link large cities, with their satellite towns and suburbs, to downtown areas, as a substitute for subways, due to its low cost potential, compared to metros and light rail (basically due to their lower turning radius, grade ability and energy efficiency). High Speed Maglev is also seen as a promising technology, with the potential do provide high quality passenger transport service between cities in the 240–1,000 km (150–625 mi) distance range into a sustainable and reliable way. This work is supposed to present, based on a compilation of a multitude of accredited and acknowledged technical sources, a review of the maglev transport technology, emphasizing its potential and risks of the low and high speed (urban and intercity) market, followed by a brief summary of some case studies.

Full textAbstract:
Ventilation fans operating in underground metropolitan tunnels are subjected to abrupt changes in operations due to the pressure wavefronts generated by the passage of the trains, and the magnitude of these pressure waves is increasing due to increasing speed of passing trains in modern mass transport systems. To avoid fans being driven into stall designers can fit fans with a stabilisation ring, i.e. a casing treatment that was found to mitigate the mechanical consequences of being inadvertedly driven into stall due to pressure pulses. A stabilisation ring is a circumferential cavity in the casing of the fan, placed upstream of the rotor in order to allow the fluid to recirculate in stalled operations. A series of fins inside this cavity is used in order to drive the recirculating fluid back into the blade vane with a proper alignment with the leading edge of the rotor. Following a previous RANS investigation that lead to the conclusion that the drive mechanism of the stabilisation ring onto the fan is based on azimuthal pressure unbalance we present here a U-RANS investigation aiming at understanding the dynamics of the interaction of the anti-stall ring with the fan and to provide insight on possible development of the geometry of the casing treatment. The fan selected for this study is a real fan for tunnel and metro applications (9 rotor blades, 1490 rpm) with a real-geometry stabilisation ring (27 fins). Computations account for different operating points (peak efficiency, design point, peak pressure and stalled operations) and rely on the low-Reynolds cubic k-ε model of Lien et al. All the simulations were carried out with the open-source OpenFOAM code. Results were validated against available experimental data and then analysed to understand the unsteady interaction between the rotor of the fan and the cavity of the stabilisation ring.
