The track fasteners may be damaged by fatigue and impact load during long-term subway operation, resulting in the failure of connecting components between rail plate, spacing support becomes larger, an increase its dynamic deformation, affecting vehicle’s running performance, and, severe cases, endangering safety. A vehicle-subway system model was created to study performance vehicles when fail...

Subway systems consume a large amount of energy each year. How to reduce the energy consumption of subway systems has already become an issue of concern in recent years. This paper proposes an energy-efficient approach to reduce the traction energy by optimizing the train operation for multiple interstations. Both the trip time and driving strategy are considered in the proposed optimization ap...

The use of traditional positioning technologies relies on the underlying infrastructures. However, for the subway environment, such positioning systems may not be available for the positioning tasks, such as the detection of the train arrivals for the passengers in the train. An alternative way is to exploit the contextual information available in the mobile devices of subway riders. To this en...

A wireless subway collision avoidance system based on zigbee network is proposed in this paper. In the proposal, all the zigbee nodes are divided into two types, fixed nodes and mobile nodes. The fixed nodes are deployed in tree topology networks overlapped with each other along the subway tunnel; the mobile nodes are installed on the trains. The core idea is as soon as a fixed node establishin...

in the contemporary era, subway terminals are known as examples of dynamic public spaces in today’s urban context, in all over the world. therefore, these constructions, that are recognized as above ground appearance of subway networks in different parts of inner and sometimes outer city areas, are the places of social encounters, predicted and unexpected happenings and various behavioral patte...
