Drawing on an ethnographic study of the installation and maintenance of Paris subway wayfinding system, this article attempts to discuss and specify previous claims that highlight stability and immutability as crucial aspects of material ordering processes. Though in designersʼ productions (guidelines, graphic manuals...), subway signs have been standardized and their consistency has been inves...

This study use noise and vibration analytical system to test and analyze the noise and vibration of subway station hall, draw the conclusion: analysis the noise test results when the vehicles through the subway station hall. The noise rises as the frequency increases, gets the peak value nearby 5000 Hz, the high of test point gives lesser influence to noise contribution. The vibration occurred ...

A rail transit network usually represents the core of a city’s public transportation system. The overall topological structures and functional features of a public transportation network, therefore, must be fully understood to assist the safety management of rail transit and planning for sustainable development. Based on the complex network theory, this study took the Beijing Subway system (BSS...

In this paper, the application layer communication protocol of CAN bus and the monitoring system for subway platform screen doors are proposed. The system framework is built, hardware of every function module for this system is selected, and the monitoring platform of epigynous machine is designed. On the basis of the above work the communication function of the monitoring system is realized, a...

1- introduction transportation and traffic is one of the major issues and challenges that are facing urban managers. so that it has become one of the major challenges in the political area. transport is one of the most important elements of urban development which is used for people and goods moving from a different geographical place to other places. in order to achieve efficient productive in...

In the current urban rail transit system, the levels of informatization and integration are not high. In order to change the traditional pattern of rail transportation operation and management, we propose an intelligent information platform of subway system based on Internet of things. Depending on the sensor nodes deployed in various functional departments of rail transport and the RFID techno...

Metagenomics is increasingly used not just to show patterns of microbial diversity but also as a culture-independent method to detect individual organisms of intense clinical, epidemiological, conservation, forensic, or regulatory interest. A widely reported metagenomic study of the New York subway suggested that the pathogens Yersinia pestis and Bacillus anthracis were part of the "normal subw...
