Abstract. Problem. The operation of transport systems a large city must ensure continuous flow passengers. subway occupies special place in the city's system. constant increase loading not only worsens conditions passenger transportation, but also shortens service life rolling stock and negatively affects reliability its operation. In future, this may cause failures stock, which means work fail...

Abstract Moving along with daily life, urban residents and commuters create characteristic spatiotemporal patterns which vary extensively the time of day. These are formed via traffic flows: accordingly, understanding impact transportation system is essential for planners to evaluate expected activities. To explore them, we examine specifically population distributions in Seoul City by analyzin...

The Sussex-Huawei Locomotion-Transportation (SHL) Recognition Challenges aim to advance and capture the state-of-the-art in locomotion transportation mode recognition from smartphone motion (inertial) sensors. goal of this series machine learning data science challenges was recognize eight activities (Still, Walk, Run, Bus, Car, Train, Subway). three focused on time-independent (SHL 2018), posi...

Travel mode identification is one of the essential steps in travel information detection with Global Positioning System (GPS) survey data. This paper presents a Support Vector Classification (SVC) model for travel mode identification with GPS data. Genetic algorithm (GA) is employed for optimizing the parameters in the model. The travel modes of walking, bicycle, subway, bus, and car are recogn...

Many cooperated web cache systems and protocols have been proposed. But, these systems need the expensive resources, such as core-link bandwidth and proxy cpu or storage, and need administrative cost to achive enough performance when the client population increases. This paper suggests a self-organizable caching system, called Subway, which is scalable and fault tolerant, with a distributed pee...

One of the inherent characteristics of transportation systems, especially steel wheel and rail systems, is that vehicles running on the roadway or trackway generate vibration which transmits through the ground into nearby buildings. As our urban areas build up or are redeveloped, it is frequently desired for a variety of reasons to place a concert hall or theater in a location which is in close...

This paper describes a declarative approach to modeling a multimodal transportation network (MTN) composed of multiple connecting transport modes, such as bus, tram, light rail, subway and commuter rail, where within each mode, service is provided on separate lines or routes. The considered model of a network of multimodal transportation processes (MTPN) provides a framework to address the need...

Inside air ventilation ducts of the confined space such as subway stations become contaminated by various contaminants and particular matters after long time operation. The accumulated various pollutants at inner duct surface easily transport and cause secondary air contamination and injure subway passengers’ respiratory system and health. In fact, only periodic duct cleaning works can improve ...

In 1863, the Metropolitan Railway of what came to be known as the London Underground successfully opened as the world’s first subway. Its high ridership spawned interest in additional links. Entrepreneurs secured funding and then proposed new lines to Parliament for approval, though only a portion were actually approved. While putative rail barons may have conducted some economic analysis, the ...

Networks can evolve even on a short-term basis. This phenomenon is well understood by network scientists, but receive little attention in empirical literature involving real-world networks. On one hand, this is due to the deceitfully fixed topology of some networks such as many physical infrastructures, whose evolution is often deemed unlikely to occur in short term; on the other hand, the lack...
