The development of Intelligent Railway Transportation Systems necessitates incorporating privacy-preserving mechanisms into AI models to protect sensitive information and enhance system efficiency.Federated learning offers a promising solution by allowing multiple clients to train models collaboratively without sharing private data.However,despite its privacy benefits,federated learning systems are vulnerable to poisoning attacks,where adversaries alter local model parameters on compromised clients and send malicious updates to the server,potentially compromising the global model’s accuracy.In this study,we introduce PMM(Perturbation coefficient Multiplied by Maximum value),a new poisoning attack method that perturbs model updates layer by layer,demonstrating the threat of poisoning attacks faced by federated learning.Extensive experiments across three distinct datasets have demonstrated PMM’s ability to significantly reduce the global model’s accuracy.Additionally,we propose an effective defense method,namely CLBL(Cluster Layer By Layer).Experiment results on three datasets have confirmed CLBL’s effectiveness. 展开更多

Based on the factors impact strength model(FISM), we studied on calculation formulas of influence strength and key elements of FISM, and analyzed the turnover time of railway freight transportation of China. The results show that wagon transfer time is the most critical factor among the three subjective factors of wagons turnover time. The FISM based analysis of wagon transfer time show that the wagon turnover time is significantly correlated with transit time with resorting. Among the seven factors of detention time of transit time with resorting, the time of waiting to departing, converging, and waiting to break-up are key factors, while the time of make-up, break-up, arrival and departure are general factors. We carried out one empirical research based on the data of Baoji East Railway Station in 2015. The results of empirical research and FISM are consistent completely. 展开更多

A comfortable environment in railway passenger coaches can be regarded as a resource for social consumption during the transport process. Railway passenger comfort benefits (RPCBs) can be regarded as a special generalized cost. In this paper, we select a series of objective and subjective indexes to formulate a quantitative method of calculating the RPCB with considering ticket fares. This method includes three steps: make the initial data dimensionless, calculate the weight of each index, and finally calculate the RPCBs. The proposed method was validated with the data collected from two types of trains: G13 from Beijing South to Shanghai Hongqiao and T109 from Beijing to Shanghai. Also, questionnaire survey was conducted in both trains. After data processing, the results show that there is a linear relationship between the RPCB and ticket fare with a correlation coefficient of 0.9616. 展开更多

In the context of building a country with a strong transportation network,railway container transportation(RCT)is an import-ant means of reducing costs,increasing efficiency,and adjusting transportation structures.Thus,its impact on regional economic devel-opment is important.Based on data from railway container-handling stations and spatial econometric models,this study discusses the differences in the development of RCT and their impact on regional economic development at different leves.This study has three main findings:first,there are significant regional differences in the development of the RCT.The intra-regional differences between the east-ern and central regions of China(which do not include Hong Kong,Macao and Taiwan)are gradually narrowing,while the regional dif-ferences in the western region are widening.Meanwhile,the intra-regional differences in important economic zones such as Pearl River Delta Economic Zone(PRDEZ),Chengdu-Chongqing Economic Zone(CYEZ),Bohai Rim Economic Zone(BHEZ),and Yangtze River Delta Economic Zone(YRDEZ)are narrowing daily.Second,the development differences of RCT in regional level and import-ant economic regions level show different trends.The unbalanced features of large regions are increasingly evident,whereas the differ-ences in economic regions are decreasing.However,the problem of overlapping RCT remains prominent.Third,the transformation of RCT development mode and fierce competition among transportation modes cause RCT to have a restraining effect on the regional eco-nomy at three levels.Rational allocation of resources and other means must be used to guide the transformation from inhibition to pro-motion,and by formulating targeted policies that will promote the development of RCT,which will improve the transportation structure and help construct a country with a strong transportation system. 展开更多

During railway operations,trains normally run as scheduled,but the occurrence of unexpected events will disrupt traffic flow and cause train deviation from the original timetable.In order to assist dispatchers in rescheduling trains,this paper introduces an innovative Human-Computer Interaction framework.This framework enables train dispatchers to propose different timetable adjustment instructions to the original or adjusted timetable.These instructions will be processed,stored,analyzed,and digested by computer program,which finally lead to the modification and calculation of the embedded mathematical model,then a new adjusted timetable will be produced and provided to dispatchers for checking and modifying.This framework can iterate for unlimited times based on dispatchers'intentions,until the final results satisfy them.A demonstration system named RTARS(Real-time Timetable Automatic Rescheduling System)is developed based on this framework and it has been applied in Beijing Railway Administration,which shows its effectiveness in reality. 展开更多

China's high-speed railway(HSR)is booming recently,the HSR's performance of energy conservation and carbon reduction has attractedmuch attention.This study developed a new life cycle model of energy consumption and greenhouse gas(GHG)emissions on China's HSR bylife cycle analysis(LCA),covering the stages of infrastructure,HSR train,and operation,based on the TLCAM(Tsinghua-LCA Model).A caseof the BeijingeShanghai HSR has been studied to show that the full life cycle energy consumption and GHG emissions of HSR transportationare 0.4 MJ km1per capita and 0.04 kg CO2ekm1per capita,respectively,which are far less than aviation,gasoline vehicles,diesel vehicles,electric vehicles and public vehicles.With the cleaner power structure and the progress of HSR train technology,the energy consumption andcarbon emissions of HSR in 2020 could be reduced by 20%compared to 2015.This study indicates that electricity generation mix structure andfull load rate are important factors influencing the life-cycle energy consumption and GHG emissions of HSR transportation.It is recommendedto improve the coverage of HSR network,accelerate train upgrades,improve the full load rate of HSR trains,and promote the low-carbondevelopment of electricity supply to strengthen and realize the low-carbon advantage of HSR transport mode in China.HSR transportationcan be used to achieve the low carbon transformation of China's transportation sector and improve oil supply safety situation. 展开更多

The maintenance window scheme(MWS) is one of the most important railway transportation organizational plans and plays an important role in ensuring railway operational safety. However, MWS setting is a very complicated process, and most countries currently do so with the help of a computer-aided decision system. In general, a decision system can generate multiple alternatives for MWS within an acceptable time. Therefore, how to choose the best option from the alternatives is a vital decision. This paper presents a novel framework for MWS evaluation based on the Chinese railway system. Specifically, the requirements of each department related to MWS setting are analysed, and we construct an evaluation indicator system for MWS based on the preferences of different departments. Then, we apply the fuzzy soft set theory to MWS evaluation, a method that not only effectively deals with evaluation of uncertain information, but also gives flexibility for experts to input their subjective judgment.Additionally, using the ‘‘AND’’ operation of soft set theory allows combing evaluation information from multiple evaluators to give comprehensive results. Finally, a case study illustrates the proposed framework, showing that the proposed evaluation indicator system and evaluation method are effective and practical. 展开更多

China and some of its trade partners in Western Europe apply different legal regimes for international carriage of goods by railway -- respectively Agreement on International Railway Freight Transportation (SMGS) and Uniform Rules Concerning the Contract of International Carriage of Goods by Rail (CIM). For transportation of goods by railway between China and Western Europe both the CIM and the SMGS are often applicable. China's initiative "the Belt and Road" promotes development of railway transport in Eurasia and creates new incentives for comparative study between those two international legal systems. This article provides a brief historical outline of comparative studies between the CIM and SMGS. This article also purports to show that some similarities and differences between the two regimes might be better understood from the perspective of comparative legal history. Taking into account inter alia the common origin of the current versions of the CIM and SMGS in the 4th revision of the CIM of 1933, differences and similarities between two legal regimes have been analysed with regard to the following topics: the scope of application of the CIM and SMGS, the nature of the carrier's liability under the CIM and SMGS; exclusivity of the CIM, exclusivity of the contract of carriage under the SMGS, period of responsibility; persons for whom the carder is liable. 展开更多
