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.

Account Based Ticketing: The Benefits and Drivers for Transit Operators

This paper aims to explore the importance and efficiency of using open payment cards in transit applications as an alternative to current propitiatory cards. This data can be beneficial to transit planners, from regular operation of the transit system down to the long-term strategic planning of the network. This paper covers several aspects of open payment cards in the transit planning context. First, the methods of payments are presented: cash, debit/credit cards, proprietary cards, and mobile payments. Then the several cases where open payments on transit are beneficial. Also reported are open card payment research conducted around the globe. Finally, the most promising online survey is performed to measure the perspective of the rider on using account-based ticketing versus the traditionally closed loop scheme. Mobility and payments are foundations pillars for developing communities and advancing economy [1].

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.

Why Fast Trains Work: An Assessment of a Fast Regional Rail System in Perth, Australia

Perth’s new 72 km long Southern Rail System opened in 2007. With a maximum speed of 137 km/hr and an average speed of almost 90 km/hr this system acts more like a new high speed rail than a suburban rail system, which in Australia typically averages around 40 km/hr for an all-stops services. The Southern Rail Line was very controversial when being planned as the urban areas served are not at all typical of those normally provided with rail but instead were highly car dependent and scattered low density land uses. Nevertheless it has been remarkably successful, carrying over 70,000 people per day (five times the patronage on the express buses it replaced) and has reached the patronage levels predicted for 2021 a decade ahead of time. The reasons for this success are analyzed and include well-designed interchanges, careful integration of bus services, the use of integrated ticketing and fares without transfer penalties and, crucially the high speed of the system when compared to competing car based trips. The Southern Rail Line in effect explodes the current paradigm of transfer penalties, exposing this as a myth. The lessons for transport planning in low density cities are significant, and are explored further in the paper.

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.

A methodology for calculating the passenger comfort benefits of railway travel

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.
