Research on Receiving Routes and Departure Routes Assignment Problem in High-speed Railway Station Based on SFLA

The assignment problem of receiving routes and departure routes in high-speed railway stations is a complex multi-objective combinatorial optimization problem. According to the characteristics of receiving routes and departure routes, assignment model of receiving routes and departure routes in High-speed railway stations is set up. Shuffled Frog Leaping Algorithm (short for SFLA) is adopted to solve that model. As using SFLA, it could reduce the amount of calculation effectively, improve the execution speed of the algorithm and increase the diversity of solutions. And with its unique mechanism of exchanging and sharing information, the solving process is not easy to fall into local optimum, which is beneficial to search the global optimal solution. Using SFLA offers a new method to set up the assignment model of receiving routes and departure routes in High-speed railway stations.

SUBSIDENCE EVALUATION OF HIGH-SPEED RAILWAY IN SHENYANG BASED ON TIME-SERIES INSAR

Abstract. More and more high-speed railway are under construction in China. The slow settlement along high-speed railway tracks and newly-built stations would lead to inhomogeneous deformation of local area, and the accumulation may be a threat to the safe operation of high-speed rail system. In this paper, surface deformation of the newly-built high-speed railway station as well as the railway lines in Shenyang region will be retrieved by time series InSAR analysis using multi-orbit COSMO-SkyMed images. This paper focuses on the non-uniform subsidence caused by the changing of local environment along the railway. The accuracy of the settlement results can be verified by cross validation of the results obtained from two different orbits during the same period.

Measurements and Analysis of Angular Characteristics and Spatial Correlation for High-Speed Railway Channels

Spatial characteristics of the propagation channel have a vital impact on the application of multi-antenna techniques. This paper analyzes angular characteristics and the spatial correlation for high-speed railway (HSR) channels, based on a novel moving virtual antenna array (MVAA) measurement scheme. The principle of the MVAA scheme is deeply investigated and is further verified by a theoretical geometry-based stochastic model. Using the MVAA scheme, virtual single-input multiple-output (SIMO) channel impulse response data are derived from single-antenna measurements in typical HSR scenarios, involving viaduct, cutting, and station. Based on the SIMO channel data, angle of arrival is extracted according to the unitary estimation of signal parameters by the rotational invariance techniques algorithm, and is compared with the theoretical result. Moreover, power angular spectrum and root mean square (rms) angular spread (AS) are provided, and the rms AS results are statistically modeled and comprehensively compared. In addition, spatial correlation is calculated and analyzed, and a rms AS-dependent spatial correlation model is newly proposed to describe the relationship between the angular dispersion and the spatial correlation. The presented results could be used in multi-antenna channel modeling and will facilitate the assessment of multi-antenna technologies for future HSR mobile communication systems.

Holmestrand, Norway: the world’s first high-speed-rail station under rock

A new 14 km double-track high-speed railway through the city of Holmestrand in Norway has greatly improved rail services on the Vestfold line since it opened in 2016. The city’s new high-speed railway station is the first in the world to be built under rock. It is accessible by way of several access tunnels from a surface carpark and a public transport interchange. The station was designed to allow high-speed trains to pass at 250 km/h while passengers are standing on the platforms. This required careful management of aerodynamic forces and governed many aspects of design and construction. Special emphasis was also placed on safety, escape routes, ventilation and noise reduction.

Numerical Investigation on the Effect of Mobile Smoke Ventilator on Fire-induced Smoke Extraction for Underground Platform in a High-speed Railway Station

Abstract Fire-induced smoke extraction for the underground platform of a high-speed railway station was investigated. Nowadays, the development of high-speed railway in China is rapid. In order to economize valuable urban space and to realize the convenient interchange to the subway, some of the high-speed railway station platforms and transfer halls are set underground. It is difficult and uneconomic to achieve static ventilation in the underground platform. Therefore, the mechanical smoke control system is the most feasible method to ensure the fire safety of the underground platform. Mobile smoke ventilator is the most common smoke exhaust equipment for fire-fighters. This paper investigates the interaction between mechanical smoke control system and mobile smoke ventilator, as well as the effect of mobile smoke ventilator under the condition of mechanical smoke control system failure. An underground island platform and underground waiting and transfer halls of an under construct high-speed railway station in south China are reconstructed in this paper. A new system with mechanical ventilation and mobile smoke ventilator is proposed. The effects of mechanical ventilation without mobile smoke ventilator are also numerically simulated by Computational Fluid Dynamics (CFD) method for comparison. The distribution of smoke and CO in the platform and influences of them on evacuation staircases are computed and analyzed. The effect of fire location on smoke spread is explored in our research. This study based on CFD modeling enables the improvement of smoke control and exhaust in underground high-speed railway station fire. The results are applicable to practical fire-fighting and rescue for underground high-speed railway station platform.

A Study of How High-Speed Railway Affects County Industry Development

Since the first Chinese high-speed railway was built in 2008, the high-speed railway industry has developed rapidly recently. Based on “China railway yearbook”, The map of China’s railway network, “China statistical yearbook” in county level, and the “China Regional Economic Statistics Year book”, we collect and sort out the various economic and society indexes of the county in China, and we set up the national city at the county level panel data, using Two-way Fixed Effect model to estimate the policy effect on the county which built the high-speed railway station. Based on the research of panel date, we can get several conclusions. Firstly, building a high-speed railway will promote the economic growth of the cities at the county level. Secondly, the opening of high-speed railway has positive and significant policy effect on the three main industries of county-level cities, especially the development of tertiary industry. Finally, the construction of high-speed rail has a strong policy impact on the county-level cities in the four regions of the eastern, western, central and northeastern regions. Among them, the construction of a high-speed railway site will promote the economic growth of the county-level high-speed rail station cities in the central region and the policy effect on the development of the tertiary industry is the strongest.

A High-Resolution, Yet Scalable Framework for Transport Infrastructure Accessibility Based on Open Big Data

Throughout the last years, open big data has brought many challenges and revealed much potential for transportation research. In this study, we show how large open datasets can be used to accurately estimate the accessibility of transportation infrastructure for whole China, a scale unprecedented in the literature. Hundreds of airports and almost one thousand high-speed railway (HSR) stations serve the tremendously growing transportation demand. These access points to the transportation networks are not equivalently distributed throughout the country. Existing large-scale studies on transportation infrastructure accessibility focus on highly-aggregated forms of land-use area, with travel times from centroids of administrative regions. Other studies analyze spatially-constrained regions with very detailed data. In this study, we design and implement a fine-grained accessibility framework based on large open data sets, which allows us to estimate the accessibility based on grid cells with a resolution of less than one square kilometer. We automatize the computation of free-flow road travel times, as well as, the public transit times, from grid cells to infrastructure elements, by using a scalable routing framework. Based on our experiments, we find that the HSR network for China is much better accessible for the population than airports. Moreover, grid cells with a high population density are much better connected to the Chinese transportation networks than other grid cells. Our methodology is generic in that it can be applied on an even larger scale (whole planet) and with different points of interest.

Transient Analysis of Electric Arc Burning at Insulated Rail Joints in High-Speed Railway Stations Based on State-Space Modeling

This paper aims to study the arc burning phenomenon of insulated rail joints in high-speed railway stations. First, combined with the actual situation of station and the grounding mode of electric multiple units, the potential difference between the two ends of insulated rail joint is calculated before the wheel’s arriving at the cutoff point. Then, transient analysis is carried out for the ordinary wheel and the discharge wheel, respectively. Each transient process is divided into three parts: the wheel reaches the cutoff point, bridges the cutoff point, and generates an arc. The equivalent state-space model is established for each part of transient process. The corresponding voltage and current waveforms are calculated by the state-space model analysis using MATLAB software. Through substituting a theoretical arc model that combines the Cassie and Mayr models into the state equation, the waveforms of arc voltage and arc current for the ordinary wheel and the discharge wheel are achieved, respectively. As a result, the transient analyses are in line with field observation records. The calculated arc waveforms appear to be in good agreement with the ones recorded by experiment.

Temporarily occupied space with metabolic-rate-initiated thermal overshoots—A case study in railway stations in transition seasons

Temporarily occupied space (TOS) is defined as an air-conditioned space in which most of occupants stay for less than a certain period (e.g., 40 min), such as post offices, supermarkets, bookstores, and banks. The definition mainly emphasizes two aspects: obvious temperature step up/down and short-term exposure periods. Typical TOSs with predominantly temperature-initiated thermal overshoots have been explored in previous studies. Indeed, apart from temperature-initiated thermal overshoots, thermal overshoots can also be initiated by other parameters, such as metabolic rates. In this view, the definition of thermal overshoots was generalized and a case study was conducted at high-speed railway station in China under conditions of transition seasons. The phenomenon of metabolic-rate-initiated thermal overshoots instead of temperature-initiated thermal overshoots was observed and explored, based on objective measurements and subjective questionnaire surveys. The results could optimize the design and operation of air conditioning and mechanical ventilation (ACMV) systems in such TOSs as embodied by railway stations. In addition, the probit analysis method for analyzing neutral temperature ranges instead of neutral temperature points was also discussed.

Length optimization of straight line connecting turnout on main line in high-speed railway station yard

Taking the development of high-speed railway in China as background, and referring to the dynamic theory and wheel-rail contact mode, dynamic analysis model was established, considering the setting position of straight lines and running conditions of train in high-speed railway station yard. Using the established model, and choosing vehicle lateral acceleration and wheel suspension as the evaluation indexes, dynamic characteristic of vehicle traveling in turnout and adjacent area on main line was analyzed, and effects on travelling safety and stability of train aroused by length variation of straight lines were calculated based on analyzing the damping rules of vibration. The results show that, a certain length of straight lines can alleviate the vibration aroused in turnout and curve (turnout), length of straight lines connecting turnouts in different sections on main line was proposed to meet the demand of traveling stability, and shortening or cancelation of straight line for the scale limitation of station yard has less influence on operation safety of train.

Modeling Passengers’ Boarding Behavior at the Platform of High Speed Railway Station

Modeling passengers’ motion at high speed railway (HSR) station has been a hot topic in the field of pedestrian flow theory. However, little effort has been made to explore the passengers’ boarding behaviors at the platform of HSR station. This study proposes a cellular automaton (CA) model to study the passengers’ boarding behavior at the platform of HSR station. Some numerical tests are conducted to explore the passengers’ movements and the complex traffic phenomena (e.g., each passenger’s trajectory, congestion, and travel time) which occur during the boarding process. The numerical results illustrate that the passengers’ inflow rate and entrance choice behavior have significant impacts on the boarding efficiency. These results can help managers to understand the passengers’ boarding behavior and to improve the boarding efficiency.

Ghost city phenomenon along China's high-speed railway grid

A fresh urbanism era appears in China with the development of high-speed railway (HSR). Voluminous numbers of local governments are designing and erecting novel cities oriented to the HSR stations with the objective of gaining benefits from the HSR system. Nevertheless, a huge number of these freshly erected districts or cities entail a tremendously high vacancy rate, thereby resulting in 'ghost cities'. The present paper commences with an outline of the China's urban HSR growth and the phenomena of ghost cities. After a literature review on worldwide urban HSR development, the reasons behind the 'ghost city phenomenon' in China are analysed. In the end, the study is concluded by proposing several suggestions for HSR development.

Use of the Conduit Flow Process for the simulation of passive mitigation measures against the piezometric damming effect at the new underground High Speed railway station of Florence

The new High Speed railway station of the city of Florence will be located below ground level inside a huge excavation, 25 m b.g.s deep, 450 m long and 50 m wide; the pit, already built, is surrounded by concrete cut-off walls causing a piezometric damming effect against the main aquifer of the Arno River. As permanent mitigation measure against the piezometric mounding, the design of the station considers a series of drain pipes drilled horizontally on up and down gradient sides of the pit and connected by blind wall tubes. A numerical finite differences model has been implemented with the Modflow code, in order to quantify the expected damming effect and to properly design the drain-based mitigation measures (i.e. frequency and length of the drains). One of the major challenges of the numeric approach was the coupling between the groundwater flow in the porous medium and the water flow towards and through the drains and the blind wall tubes connecting the sides of the excavation. Thus, the drains were simulated using a recently published Modflow Process originally developed for karst conduits (Conduit Flow Process – CFP), which allows combining the groundwater flow in the porous medium with laminar or turbulent flow into pipes. In order to guarantee an acceptable head differential between both sides of the excavation, the results showed that the system should permit a discharge flow rate of about 0.026 m3/s, considering a hydraulic gradient equal to 0.5% (i.e. hydraulic gradient from the averaged piezometric distribution before pit excavation). Conductance turned out to be the most influent parameter towards the effectiveness of the drainage system.

광명역 고속철도 역사를 활용한 1.5MW급 태양광발전시스템 설계 연구

In the 21st yearly session of the Conference of the Parties (COP 21) of the 2015 United Nations Climate Change Conference, held in Paris, France, in December 2015, the “Paris Agreement” was negotiated; this is a new global agreement on the reduction of climate change, which encourages every country to participate in countermeasures for global climate change. Along with such movements, the electric railway sector has also been actively engaged in low carbon technology. This paper studied the building of a 1.5MW photovoltaic power generation system using the rooftop of the Gwangmyeong Station Building, which is the largest roof among the high-speed railway station buildings in Korea; this station has passenger traffic that reached about 7 million in 2014. For this study, we configured an optimized photovoltaic (PV) power generation system and then estimated the expected annual energy production by using PV system software; we also calculated the expected revenue that could be obtained by linking this source to the power distribution system. The obtained data were used to analyze the contribution of low-carbon energy that could be obtained by introducing a PV power generation system on the roof of an electric railway station building.
