This paper evaluates the effect of the installation of "high-wheel" turnstiles on the incidence of fare evasion at a subway station in New York City. Ridership, summons and arrest data at the treatment station and two adjacent control stations suggest that the new high-wheel turnstiles were somewhat effective in reducing fare evasion, with little evidence of displacement. In light of these resu...

A simple method for correcting for the loading effects of aethalometer data is presented. The formula BC(CORRECTED) = (1 + k x ATN) x BC(NONCORRECTED), where ATN is the attenuation and BC is black carbon, was used for correcting aethalometer data obtained from measurements at three different sites: a subway station in Helsinki, an urban background measurement station in Helsinki, and a rural st...

today’s transportation is known as one of the most important elements of urban development structure. public transportation, according to its more extensive functional capacity, can play a vital role in wider scale. transit oriented development by focusing on the subways is one of the special approaches in this field. recently, tehran public transport fleet has significantly improved especially...

An integrated urban transportation system usually consists of multiple transport modes that have complementary characteristics of capacities, speeds, and costs, facilitating smooth passenger transfers according to planned schedules. However, such an integration is not designed to operate under disruptive events, e.g., a signal failure at a subway station or a breakdown of a bus, which have ripp...

In this paper, three-dimensional ultrasonic anemometer and multi-channel have been used to monitor the flow field of a subway station in Beijing. Based on releasing sulfur hexafluoride (SF6) hall, gas transmission diffusion range studied. The results show that under natural ventilation, would be controlled by regular mainstream field. Because obvious subsidence heavy tends accumulate ground. ai...

Incremental dynamic analysis constitutes the basis of seismic performance evaluation and vulnerability assessment. In this paper, a typical two-story three-span subway station structure is selected as an example its incremental procedure are presented, including selection ground motion, intensity measure limit state determination. The provided in study can be for further on design underground s...
