Research at home and abroad shows that subway excavation often causes soil stress loss, resulting in settlement deformation horizontal displacement of stratum. Therefore, combined with the special engineering geological conditions Kunming area, foundation caused by is studied, so as to provide an important for proposing protection measures surrounding buildings buried pipelines promoting constr...

A new concept of subway station capacity (SSC) is defined according to the gathering and scattering process. A queuing network analytical model of station is created for calculating SSC, which is built by M/G/C/C state dependent queuing network and discrete time Markov chain (DTMC). Based on the definition and the analytical queuing network, a SSC optimization model is developed, whose objectiv...

In this paper, a problem for safety of bogie frame of subway vehicle under overload situation has been discussed. Firstly, the structure of bogie frame and service condition are introduced to explain the reason caused fatigue failure. Then, the testing points are selected in terms of the structure of bogie frame, the characteristics of processing technique, load transfer path and the operation ...

Transit infrastructure is a critical asset for economic activity yet costly to build in dense urban environments. We measure the benefit of Second Avenue Subway extension New York City, most expensive transit project recent memory, by analyzing local real estate prices which capitalize benefits spillovers. find 8% price increases, creating $5.5 billion new property value. Using cell phone ping ...

Traditional control algorithms in Automatic Train Operation (ATO) system have some drawbacks, such as high energy consumption and low comfort. In this paper, two Intelligent Train Operation (ITO) models based on data mining for the subway train control are proposed combining with the driving experience. Firstly the training data set is sorted out and sieved out from the real train operation dat...

We investigate the relationship between the extent of a city’s subway network, its population and its spatial configuration. To accomplish this investigation, for a sample of the 632 largest cities in the world, we construct panel data describing the extent of each of the 138 subway systems in these cities, their population, and measures of centralization calculated from lights at night data. T...
