Application and realization of key technologies in China railway e-ticketing system

Purpose–With the yearly increase of mileage and passenger volume in China’s high-speed railway,the problems of traditional paper railway tickets have become increasingly prominent,including complexity of business handling process,low efficiency of ticket inspection and high cost of usage and management.This paper aims to make extensive references to successful experiences of electronic ticket applications both domestically and internationally.The research on key technologies and system implementation of railway electronic ticket with Chinese characteristics has been carried out.Design/methodology/approach–Research in key technologies is conducted including synchronization technique in distributed heterogeneous database system,the grid-oriented passenger service record(PSR)data storage model,efficient access to massive PSR data under high concurrency condition,the linkage between face recognition service platforms and various terminals in large scenarios,and two-factor authentication of the e-ticket identification code based on the key and the user identity information.Focusing on the key technologies and architecture the of existing ticketing system,multiple service resources are expanded and developed such as electronic ticket clusters,PSR clusters,face recognition clusters and electronic ticket identification code clusters.Findings–The proportion of paper ticket printed has dropped to 20%,saving more than 2 billion tickets annually since the launch of the application of E-ticketing nationwide.The average time for passengers to pass through the automatic ticket gates has decreased from 3 seconds to 1.3 seconds,significantly improving the efficiency of passenger transport organization.Meanwhile,problems of paper ticket counterfeiting,reselling and loss have been generally eliminated.Originality/value–E-ticketing has laid a technical foundation for the further development of railway passenger transport services in the direction of digitalization and intelligence.

Analysis on Land Ticket Transaction System of Chongqing Municipality

On the basis of analyzing essence of land ticket system of Chongqing Municipality and its transaction process,this paper studies the relationship between government and farmers and between city and countryside,and discusses the drawbacks of land ticket system in Chongqing Municipality. Results show that inherent drawbacks of land ticket system and wrong guidance of policies lead to suspicion of land ticket system occupying rural resources. Interregional exploitation and intergenerational exploitation are inherent mechanism of city exploiting countryside. Finally,it proposes increasing construction land index to satisfy demand of new socialist countryside construction primarily,to ensure rural social stability; Later,use land ticket index to fill the gap of construction land in economically developed areas,so as to alleviate conflict of urban land use and maximize circulation value of rural construction land. It is expected to provide theoretical reference for relevant departments to regulate land ticket transaction system and realize the harmonious development,between urban and rural areas.

Factors Influencing the Adoption of E-Ticketing System in the Bus Transport Sector in Ghana

Electronic ticketing (E-ticketing), an innovative mode of issuing and delivering tickets, is becoming prevalent and is employed by many transport companies in Europe, America, Asia, and some parts of Africa to reduce the cost that goes with printing tickets. This study investigated E-ticketing adoption in the bus transport sector in the Kumasi Metropolis of Ghana. The study applied the Technology Acceptance Model (TAM), and the Structural Equation Modelling technique was used to analyse the factors affecting the intention to use the E-ticketing system. In that regard, the study was based on perceived usefulness, perceived ease of use, subjective norms, and demographic variables. Quantitative research approaches were used by distributing questionnaires to 392 passengers, employing the cluster and random sampling techniques. Findings from the study showed that perceived usefulness and subjective norm were the significant factors affecting passengers’ intention to adopt the E-ticketing system. Besides, perceived ease of use and subjective norms were significant in predicting passengers’ perceived usefulness of adopting E-ticketing system. The findings of this research will provide the government, industrial players, and the entire public a better understanding of the perceived factors that could enhance or serve as a barrier to passengers’ adoption of the E-ticketing system. This can also lead to the development of effective E-ticketing marketing strategies.

Incident and Problem Ticket Clustering and Classification Using Deep Learning

A holistic analysis of problem and incident tickets in a real production cloud service environment is presented in this paper.By extracting different bags of words,we use principal component analysis(PCA)to examine the clustering characteristics of these tickets.Then Kmeans and latent Dirichlet allocation(LDA)are applied to show the potential clusters within this Cloud environment.The second part of our study uses a pre-trained bidirectional encoder representation from transformers(BERT)model to classify the tickets,with the goal of predicting the optimal dispatching department for a given ticket.Experimental results show that due to the unique characteristics of ticket description,pre-processing with domain knowledge turns out to be critical in both clustering and classification.Our classification model yields 86%accuracy when predicting the target dispatching department.
