Abstract By analyzing the timing characteristics of historical temperature data subway sensors, aiming at problem poor accuracy a single prediction model, combined with long-term trend, multi period and irregular change data, this paper proposes model based on Long Short-Term Memory network (LSTM) Support Vector Regression (SVR) theory, mean error LSTM-SVR is lower than which can predict statio...

Abstract Because of its large capacity, high efficiency, and energy savings, the subway has gradually become primary mode transportation for citizens. A density passengers exists within a large-passenger-flow station, number casualties injuries during fire emergency is substantial. In this paper, Pathfinder software on-site measured data Pingzhou station in Shenzhen were utilized to simulate ev...

To every d-dimensional polytope P with centrally symmetric facets one can assign a “subway map” such that every line of this “subway” contains exactly the facets parallel to one of the ridges of P . The belt diameter of P is the maximum number of subway lines one needs to use to get from one facet to another. We prove that the belt diameter of a d-dimensional space-filling zonotope does not exc...

Train-induced unsteady airflow (TIUA) has a great effect on the ventilation and thermal environment of subway line. Track area, connecting tunnel with station, is source TIUA acting station. Exploring characteristics track area contributes to utilizing for improving station environment. In this study, 1D numerical model according an actual line was established by IDA Tunnel software, analyse ra...

For the time scheduling problem of each station's muck transportation vehicle and processing center during construction under-construction subway station, a optimization model with shortest waiting plant as objective function is established, genetic algorithm improved by repairing chromosomes individuals who violate constraints introducing elite strategy. The effectiveness verified examples. re...

Traditional BAS systems in subway stations have problems such as inflexible deployment, high implementation costs, weak edge computing capabilities, and low integration, which are not conducive to the realization of convenience intelligence. In response traditional system, Guangzhou Railway Institute designed applied a brand-new station equipment IOT management system. This article first analyz...

A transit ridership study is an essential part of sustainability, and can provide a deep understanding of people’s travel patterns for efficient transportation development and urbanization. However, there is a lack of empirical studies comparing subway and taxi services, and their interactions within a city, that is to say, the interdependent transportation networks. Incorporating new data, thi...

BACKGROUND AND OBJECTIVES Although mass transit systems are convenient and efficient for urban people, little attention has been paid to the potential hearing hazard from their noise. The purpose of the current study was to measure and analyze levels of subway interior noise at peak commuter times and to provide information about commuters' daily dose of noise exposure. MATERIALS AND METHODS ...

Subway transportation is one of the most prevalent urban methods globally. Millions people around globe use this medium as their mode daily. However, subway stations may be highly prone to fire, smoke, or explosion accidents. The safety using demands a robust and practical framework assess fire hazards risks. This study provides methodology risk at station. integrates fault tree analysis (FTA) ...
