ineffective transport system in large cities including tehran, creates important environmental problems such as increases in fuel consumption resulting in loss of large amounts of non renewal natural resources.the increasing of oil consumption in tehran city is mostly for the inefficiency of transportation systems. this problem is one of the main causes of destruction and ending of environmenta...

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...

Pedestrians intercepted near the exits of a subway station in downtown Hong Kong were surveyed using a questionnaire and quota sampling in October 2012. The survey sampled 408 residents and tourists aged 16 and above. The awareness of the 16 ads ranged from 18 to 80 percent with an average 43.5 percent. The layouts of the two subway ads received highest awareness were focused and had a clear di...

Modeling and analysis of a subway fire emergency response processes are extremely important in metro operation. In this study, a Petri net based approach is proposed to model and analyze the time and resource issues of subway fire emergency response processes. More specifically, the formal specification of subway fire emergency response process is first defined and a real subway fire response p...

A prior study in New York City observed that airborne concentrations of three metals found in steel - iron, manganese, and chromium - are more than 100 times higher in the subway system than in aboveground air. To investigate the potential for health effects of exposure at these levels, we conducted a pilot study of subway workers comparing personal exposures to steel dust with biomarkers of me...

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...
