“…If the rough construction of the vehicle does not allow placing both steps in the space under the interior floor, then a lower step is installed under the vehicle bottom. This is not very popular, because if the vehicle is operated at low values of temperatures, then snow and ice could limit the movement of the auxiliary step [20].…”

This paper deals with a solution for faster and safer boarding and leaving of passengers at railway station platforms from 150 mm to 550 mm higher than the head of the rail. This conception is based on the requirements of railway infrastructure administrators, transporters and also manufacturers of passenger rolling stock. This device is designed for the new double-deck railway vehicle for suburban and regional transport, which fulfils legislative and normative requirements that are specified for the selected area of vehicle construction and operational features. Selected parts of the construction were verified through a series of simulation analyses. This article also includes a study that deals with optimization of the boarding area considering designed changes in the construction of the floor and a draft for modification of the vertical clearance of the boarding entrance area in a rough construction of the vehicle.

Methodology of the heat outcome from the bus compartment in terms of duration factor of cooling and heating capacity is introduced. Value of the air temperature change in the compartment was calculated. The balance method of the spent heat is used to assess the level of keeping a proper temperature environment in the bus saloon when a comfortable microclimate is created for passengers via the proper conditioning system functioning. Models of the heat transmission notions were used for calculation regarding different categories of the heat load creation. A developed numeric algorithm was introduced in the article as well as a program for modelling the transitory heat processes in the compartment of the city bus equipped with an air-conditioner enabling to take into account various constructive decisions in the system of comfortable provision of city buses and model unstable heat processes.

“…As early as the 1970s, some foreign countries have already adopted the automatic fare collection system (AFCS) in urban rail transit (URT) [1]. The current social development and technological advancement have seen the formation of a more intelligent and reliable AFCS [2]. Multiple lines under the same operating entity share a multilines center (MLC) to realize rail transit networking operation through the same MLC and the AFC clearing center (ACC) interface; thus, MLC is the core of the multiline AFCS [3].…”

“…Additionally, new features, such as microservices, virtualization, and containerization also require the infrastructure layer to provide the function of sharing data volumes and files [6]. In the subway MLC system, there are mainly four kinds of data files [7]: (1) data interface between MLC and subordinate systems, which is stipulated by the urban subway network specification and contains messages and data files, among which the transaction data files and MLC parameter files are usually transmitted over FTP; (2) data interface between MLC and the subway external system [8], which is jointly negotiated by the MLC system and the external system and can be presented invarious forms, such as messages, message queues, and files. The reconciliation data files are usually transmitted over FTP; (3) intertransmitting data files among subsystems within MLC.…”

Automatic fare collection system (AFCS) is a modern, automatic, networked toll collection system for rail transit ticket sales, collection, billing, charging, statistics, sorting, and management. To realize the subway transit networking operation, this paper designs the subway AFCS based on a distributed file system (DFS), namely, Gluster File System (GlusterFS). Firstly, the multiline center (MLC) in the subway AFCS is designed to analyze the status and current situation of distributed file processing in subway MLC system; secondly, the relevant technical theories are summarized, the Bayesian Network (BN) theoretical model and DFS are explored, and the principles of four DFS are comparatively analyzed; thirdly, the architecture and cluster mode of GlusterFS is expounded, and then based on GlusterFS, the architecture of subway AFCS is discussed. This paper presents several innovation points: first, the subway AFCS is designed based on GlusterFS by analyzing and aiming at the functional requirements, performance requirements, and safety requirements of the MLC subway system; second, the safety risk analysis (SRA) of AFCS is conducted from six security requirements, and a Web scanning system is designed to ensure the system data security. Finally, the design scheme is used to analyze the subway passenger flow and power consumption. The results demonstrate that the design scheme can competently adapt to three different application scenarios. Through comparison of two deployment modes of the Web scanning system, the data security Web scanning system can ensure the safe operation of the AFCS. Furthermore, the statistical analysis of subway passenger flow and power supply data shows that the proposed scheme can support the smooth operation of the subway system, which has significant practical value.
