Fire accidents often lead to tremendous losses and smoke has been reported be the main cause of these heavy casualties. Accordingly, movement can influence escape confinement is particular significant. Dynamics Simulator software (FDS) was utilized carry out complementary full scale numerical simulations fire accident in a subway station. Different measure prevention exhaust were adopted differ...

In this paper, we propose a new method to compute the barycenter of large weighted graphs endowed with probability measures on their nodes. We suppose that the edge weights are distances between the nodes and that the probability measure on the nodes is related to events observed there. For instance, a graph can represent a subway network: its edge weights are the distance between two stations,...

Stations are the main components of the subway systems. Despite the progress in the construction and maintenance, stations have always been exposed to the natural and man-made disasters. In such incidents, the station’s evacuation capability has a direct relation with a passenger's life. Various factors affect the station's evacuation capability. Investigation of these factors and evaluation of...

It is urgent to digitize the subway equipment detect changes in components station time. In this paper, we use 3D point cloud of as a benchmark, compare it with completed BIM model station, find out and retrieve components. First, obtained Xiamen Metro Station. Second, labeled 140 pairs matched component cloud. Third, constructed Siamese network which embedded triplet loss learn feature descrip...

Abstract With the maturity of big data technology, analyzing residents’ travel habits and tracks has become an important research direction in field intelligent transportation study. In this paper, based on subway bus ride data, a subway-bus double-layer network model was established using complex theory, taking optimal traffic efficiency as goal, structure optimization method is proposed, empi...
