Optimization for bilevel spatial configuration of underground space surrounding high-speed railway station in China from the perspective of urban morphology

The rapid growth of high-speed railways has led to the development of underground spaces surrounding high-speed railway stations (USSHRSs). The evolution of USSHRS has enhanced the space utilization efficiency. As USSHRSs expand, the layout of the underground connectivity network becomes increasingly intricate. Additionally, pedestrian behavior in USSHRSs transitions from mere passing to longer stays, and its spatial configuration becomes more difficult to evaluate. To date, studies have mostly focused on the structural analysis or inner underground space relationship of USSHRSs. A research gap exists in the field of USSHRS spatial configuration from the perspective of urban development. To fill this research gap, this study focused on the spatial configuration of the USSHRS from the perspective of urban morphology and established a quantitative analysis method for USSHRSs at both global and local levels. At the global level, we devised a method for measuring the USSHRS spatial configuration using pedestrian composite accessibility based on a complex network. At the local level, we used space syntax to study the inner spatial configuration problems of USSHRSs. Finally, we used the Shanghai Hongqiao Station (Shanghai, China) as a case study. The results revealed that the spatial configuration optimization of the USSHRS must improve the connectivity efficiency of the USSHRS, and the corresponding functional layout should also be optimized towards a centralized layout. This study aims to provide decision-making support for the planning and layout of complicated USSHRS and to highlight the role of USSHRS in urban sustainable development.

Research on vibration characteristics of a straddle-type station induced by moving trains

The novelty of straddle-type railway stations as a modern railway infrastructure necessitates thoroughly examining their vibration behavior under high-speed train-induced vibrations. This study focuses on Shangrao station, the inaugural straddle-type high-speed railway station in China, to investigate its vibration properties induced by high-speed trains. A comprehensive finite element model is developed and validated against empirical data to ensure accuracy. The vibration response and propagation patterns induced by railway operations are extensively studied under diverse operational conditions. The results illustrate that the peak acceleration in the vertical (Z) direction significantly exceeds that in the horizontal (X and Y) directions in most test cases. Moreover, under consistent train speed and axle load, the multiple parallel traffic scenario results in higher peak accelerations in all directions compared to the grade separation traffic scenario. Additionally, a positive correlation exists between the railway platform’s maximum amplitude, corresponding frequency, and train speed. Furthermore, increased train axle load leads to higher peak accelerations in the station building. The findings of this research offer valuable insights for the predictive modeling and design of high-speed straddle-type railway stations, providing essential technical support for future station projects.

Attention Mechanism with Spatial-Temporal Joint Deep Learning Model for the Forecasting of Short-Term Passenger Flow Distribution at the Railway Station

Accurate understanding of passenger flow distribution is crucial for effective station crowd management. However, due to the complexity and randomness of passenger flow and the unclear spatial-temporal correlation between functional areas within the station, predicting the spatiotemporal distribution dynamics of inflow and future short-term distribution trends is challenging. Emerging deep learning models offer valuable insights for accurately predicting passenger flow distribution. Thus, we propose a deep learning architecture, named “ST-Bi-LSTM,” which combines a bidirectional long short-term memory network with a spatial-temporal attention mechanism. Initially, we outline the methodologies of Bi-LSTM, the DeepWalk-based spatial attention mechanism, and the temporal attention mechanism. The spatial attention mechanism is employed to extract station spatial network topology information and enhance the representation of passenger flow characteristics in highly correlated areas during the forecasting process. Simultaneously, the temporal attention Bi-LSTM is utilized for capturing temporal correlations. The architecture comprises four branches dedicated to station real-time video monitoring data, spatial network topology, function area attributes, and train timetables. Subsequently, leveraging in-station CCTV data, passenger travel behavior data, and train timetables, we apply the architecture to the Tianjin West High-Speed Railway Station. We conduct a comparative analysis of the prediction performance and time complexity of the proposed architecture against existing baseline models, demonstrating superior performance and robustness exhibited by the ST-Bi-LSTM model (achieving a reduction in RMSE of over 10%). This study facilitates the transition of station management from passive response to active prediction of station passenger flow dynamics.

Impact force curve feature and failure mode identification method of concrete-filled steel tube members under lateral impact

A collision accident caused by derailed trains is a potential safety hazard for the structure adjacent to high-speed rail lines. Concrete-filled steel tube (CFST) columns are frequently utilized in modern high-speed railway stations, however CFST station columns may suffer severe damage from train collisions because of their high impact energy. Therefore, the method of identifying CFST members' failure modes under large impact energy was investigated in this paper. Adopting numerical simulation by LS-DYNA, the corresponding relationship between the local indentation and impact process was researched, the characteristic impact force time-history curve was proposed, and the effects of impactor and CFST specimen parameters on impact force feature were analyzed. The plateau proportion was established and quantified, then the mapping relationship between plateau proportion and failure degree was acquired. Research results indicated that local indentation developed primarily at impact force plateau stage. CFST specimens showed bending deflection when plateau proportion was below 67.5%, experienced fracture failure when it was above 77%, and exhibited crack failure when it was in between respectively. Finally, the empirical formulas for plateau proportion and maximum deflection were established, and a simplified approach for predicting the failure modes was put forward. The research provides suggestions for identifying damage patterns and strengthening CFST columns subjected to lateral impact loads.

ABSTRACT To capture the factors influencing and measurements of pedestrian accessibility to high-speed rail station areas, ensure the balance between the transportation function and place performance of high-speed railway station areas, the correlation factors and laws of pedestrian space characteristics of high-speed railway station areas under different development modes are studied through the comparison of typical high-speed railway station areas in China and Japan.

How does the location of high-speed railway stations affect the emission reduction effect of industrial structure upgrading?

The opening of high-speed railway (HSR) has accelerated the reorganization and reallocation of regional production elements, and constantly promoted the adjustment and upgrading of industrial structure. The cleaner production effect produced by industrial structure upgrading is of great significance to industrial pollution reduction. As a bridge connecting resources within the city and elements outside the city, the location of HSR stations has become an important factor affecting the structural emission reduction effect. Based on the data of 285 prefecture level and above cities in China from 2004 to 2018, this paper investigates the structural emission reduction effects of HSR opening and the impact of HSR station location on it by employing difference-in-differences (DID) model combined with mediation effect method. The results demonstrate that the opening of HSR has significant structural emission reduction effect, and the upgrading of inter-industry structure and the intra-industry structure are important mechanisms for HSR to achieve industrial emission reduction. The structural emission reduction effect of HSR opening is closely related to the location of HSR stations. With the increase of the distance between HSR station and city center, the industrial structure upgrading effect will continue to weaken, thus inhibiting the exertion of structural emission reduction effect, of which 10km away from the city center is the optimal site strategy for the HSR service to give full play to the structural emission reduction effect, and exceeding 50km will be significantly detrimental to its role in promoting industrial structure upgrading.

Differential Influences of High-Speed Railway Stations on the Surrounding Construction Land Expansion and Institutional Analysis: The Case of Taiwan and Hainan

The purpose of this paper is to compare the differential impact of Taiwan High-speed Railway (T-HSR) and Hainan East Ring High-speed Railway (HER-HSR) stations on the surrounding construction land expansion, reveal the underlying institutional reasons, and then provide policy recommendations for coordinating the rational development of land resources and ecological environment protection around high-speed railway (HSR) stations. The research methods include the Institutional Analysis and Development (IAD) framework, buffer analysis, and GIS spatial analysis. The results show that (1) The spillover impact of HSR stations on the surrounding construction land expansion is the result of the game between different actors around the development and protection of land around HSR stations under the action scenarios of various external factors. The surrounding construction land of 12 stations of T-HSR increased by 269.98 km2 within the study scope and period, while the surrounding area of 10 stations in HER-HSR increased by 187.61 km2. (2) There are nine stations in T-HSR that affect the expansion of surrounding construction land within 1.0–3.0 km and lead to the expansion of construction land of 22.44 km2, while there are six stations in HER-HSR that affect the expansion of construction land within 1.5–3.5 km and lead to the expansion of construction land of 24.20 km2. Other stations cannot effectively identify their areas of influence due to other reasons. (3) Each station of HER-HSR has a stronger influence intensity and degree on the expansion of surrounding construction land than that of T-HSR, which is closely related to institutional factors such as land planning, land property rights, and public participation. In conclusion, the differences in land planning, land property rights, public participation, and other basic systems will lead to differences in the expansion of surrounding construction land for HSR stations. This research aims to provide institutional adjustment suggestions to achieve coordinated economic development and ecological protection around HSR stations in two Chinese islands with different institutional environments.

Shaking Table Test on Composite Isolation System of High-speed Railway Station with Integrated Station-Bridge Structure

This paper investigated the seismic performance of a typical “Integrated Station-Bridge high-speed railway station structure with a composite isolation system. The influential mechanism of the structure with isolation system was analyzed based on shaking table tests, mainly investigating on the failure mode, acceleration response and displacement response. Besides, a parameter optimization method of isolation layer for long-span structures was proposed based on genetic algorithm to better enhance the isolation performance of the large-span structure. The research revealed that there was no obvious damage to the composite isolation system under the PGA = 0.82 g. The nature frequency of the structure with isolation system is only 12.5% of that of non-isolation structure. The first three natural vibration frequency of the structure with isolation system only reduce 3.4%, 3.2%, 6.14% after the PGA = 1.27 g, that of the non-isolation structure reduce by more than 20%. The acceleration amplification factor of each layer of composite isolation system is less than 1, in particular, that of truss is about 0.3. The displacement response and acceleration response of the structure with isolation system have been reduced by about 90%. The proposed optimization method of isolation layer parameters provides an important reference for the isolation design for high-speed railway stations.

Access to capital and energy efficiency: How high-speed rail investments benefit high-tech firms

This study examines how high-speed rail network impacts the energy consumption of hi-tech firms along the line. The results show that the opening of high-speed railway stations in a county leads to reduction in energy consumption by hi-tech firms in the county. This effect is stronger with increased density of railway lines in the region. The study identifies two key mechanisms underlying this effect: enhanced financing access and increased overseas outreach. Our findings reveal that improved financing access to public market capital, bank loans, and venture financing enables hi-tech firms to invest in international outreach activities. We also conduct additional analysis to explore nuanced conditions regarding the types of hi-tech firms that benefit the most from being located in a high-speed rail city. Contributions to the emerging field of corporate energy saving are discussed.

Tests and deflection calculation method for circular concrete-filled steel tubular columns under very low-elevation lateral impact loads

An experimental investigation of circular concrete-filled steel tubular (CFST) columns subjected to very low-elevation lateral impacts was performed. Six circular CFST members were prepared for lateral impact tests according to the typical CFST columns in high-speed railway stations in China, and the impact location was at the height of the 2/9 column. The tests had three variables: the thickness of the steel tube, the impact velocity, and the axial load. The failure modes were determined in the tests, along with the time histories of the impact force and the deflection at the impact location. A finite-element analysis was performed to examine the effects of the axial load and scaling on the maximum deflection. The results show that with the increase of axial compression ratio, the impact resistance of the member first increases and then weakens. According to the travelling plastic hinge theory, a three-stage rigid plastic mechanical model was employed to describe the impact process, in which the impact location was at the non-mid-span, and a deflection calculation method for CFST applicable to any impact position was developed. A comparison with the test results indicated that deflections can be calculated with reasonable accuracy using the proposed method.

Train rescheduling and platforming in large high-speed railway stations

To deal with train delays in large high-speed railway stations, a multi-objective mixed-integer nonlinear programming (MO-MINLP) optimization model was proposed. The model used the arrival time, departure time, track occupation, and route selection as the decision variables and fully considered the station infrastructure layout, train operational requirements, and time standards as limiting factors. The optimization objective was to minimize train delays and reduce track and route adjustments. To realize the large-scale and rapid solution of the MO-MINLP model, this study proposed a rolling horizon optimization algorithm that used “half an hour” as a time interval and solved the rescheduling and platforming problem of each time interval step-by-step. In numerical experiments, 227 train movements under delay circumstances in Hangzhoudong station were optimized by using the proposed model and solution algorithm. The results show that the proposed MO-MINLP model could resolve route conflicts, compress unnecessary dwell times, and reduce train delays; the solution algorithm could efficiently increase the computational speed. The maximum solution time for optimizing the 227 train movements is 15 min 24 s.

A multi-agent simulation based train platforming research for facilitating passenger transfer in a high-speed railway station

The train platforming problem is one of the most investigated topics in the train operation field. However, a systematic understanding of how train platforming improves the convenience of passenger transfer procedures is still lacking. To face the rapidly growing transfer demands in the high-speed railway station, this paper proposes a transfer-facilitating-oriented train platforming approach based on a multi-agent train operation simulation model. By evaluating the transfer connection quality using an indicator named Transfer Connection Strength(TCS), which considers transfer distance and transfer time, the proposed transfer-facilitating-oriented train platforming strategies can establish more convenient transfer connections and so improve the transfer service. A track occupation horizon based on the modelling of accurate train running processes is utilized to detect route conflicts and guarantee conflict-free train operations in the simulation model, enabling the solutions’ feasibility of train platforming to be taken into account. A series of simulation experiments are conducted using real data of Zhengzhou East station in China. The experiment results show that, the proposed transfer-facilitating-oriented train platforming strategies are capable of obtaining a greater number of convenient transfer connections. The feasibility can be guaranteed by permitted train delays and route conflict detection for the succeeding trains in a forward-looking period. Additionally, the platform assignment plans can be generated with a specified priority of transfer distance or transfer time.

Analysis of human-induced vibration response in elevated waiting hall of Beijing Fengtai High-Speed Railway Station

This study applies the IABSE specification model, the Chen Jun model, and two types of load models developed in this paper to analyze the human-induced vibration response of the Fengtai Station waiting hall project. Three different analysis scenarios were selected, and the load curves, acceleration response curves, Fourier amplitude spectra curves, and acceleration contour maps of the four load models were compared under the same scenario. It was found that the load model with a 75% probability established in this paper is similar to the Chen Jun model, while there are some differences between the load model with a 95% probability in this paper and the IABSE specification model. This research provides a reference for establishing pedestrian load models based on the walking habits of Chinese people and analyzing the differences between these models and existing pedestrian load models in engineering applications.

An Integrated Method for Reducing Arrival Interval by Optimizing Train Operation and Route Setting

The arrival interval at high-speed railway stations is one of the key factors that restrict the improvement of the train following intervals. In the process of practical railway operation, sudden conflicts occur sometimes. Especially when the conflict arises at the station, because the home signal cannot be opened in time, the emergency may affect the adjustment of the train operation under the scheduled timetable, resulting in a longer train following interval or even delay. With the development of artificial intelligence and the deep integration of big data, the architecture of train operation control and dispatch integration is gradually improving from the theoretical point. Based on this and inspired by the Green Wave policy, we propose an integrated operation method that reduces the arrival interval by avoiding unnecessary stops in front of the home signal and increasing the running speed of trains through the throat area. It is a two-step optimization method combining both intelligent optimization and mathematical–theoretical analysis algorithms. In the first step, the recommended approaching speed and position are obtained by analytical calculation. In the second step, the speed profile from the current position to the position corresponding to the recommended approaching speed is optimized by intelligent optimization algorithms. Finally, the integrated method is verified through the analysis of two distinct case studies. The first case study utilizes data from the Beijing–Shanghai high-speed railway line, while the second one is based on the field test. The numerical result shows that the proposed method could save the entry running time effectively, compared with the normal strategy given by the train driver. The method can mitigate controllable conflict events occurring at the station and provides theoretical support for practical operation.
