Commuters can complete their “home-work-home” trips by three options: subway-only mode, auto-only mode, and park-and-ride mode on a bottleneck-constrained corridor. The purpose of this paper is to enhance the insights into pricing mechanism for subway and parking and corresponding mode choice behavior on the corridor with elastic demand. A nested logit-based stochastic user equilibrium model is...

The fast pace of urbanization has given rise to complex transportation networks, such as subway systems, that deploy smart card readers generating detailed transactions of mobility. Predictions of human movement based on these transaction streams represents tremendous new opportunities from optimizing fleet allocation of on-demand transportation such as UBER and LYFT to dynamic pricing of servi...

Problem statement: Automated subway train-braking system require perfection, efficiency and fast response. In order to cope with this concerns, an appropriate algorithm need to be developed which need to be implemented in hardware for faster response. Approach: In this research, the FPGA realization of fuzzy based subway train braking system has been presented on an Alter FLEX10K device to prov...

Recently, with the availability of various traffic datasets, human mobility has been studied in different contexts. Researchers attempt to understand the collective behaviors of human movement with respect to the spatio-temporal distribution in traffic dynamics, from which a gravitational scaling law characterizing the relation between the traffic flow, population and distance has been found. H...

Subway systems worldwide transport more than 100 million people daily; therefore, air quality on station platforms and inside trains is an important urban air pollution issue. We examined the microbiological composition and abundance in space and time of bioaerosols collected in the Barcelona subway system during a cold period. Quantitative PCR was used to quantify total bacteria, Aspergillus f...

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...

Tehran suburb city rail Exploitation Company (Tehran subway) presents public transportation services to more than 3 million people in a day. Therefore, the way these services are presented and customer satisfactions’ rate with the services presented to enjoy high importance. In the matters applied to the survey, first the expectations that users of this public transportation system have and the...

BACKGROUND Obesity is an epidemic in the United States. Two-thirds of the population is overweight and does not get enough exercise. Eastern cities are full of escalators that transport obese Americans to and from the subway. Walking stairs is a moderate activity requiring 3-6 metabolic equivalent tasks (METS) and burning 3.5-7 kcal/min. We determined the caloric expenditure and potential weigh...

washers, fans and other devices may be required. This kind of setup is typically a requisite for the warm air in the summer to create a comfortable environment for the passengers. The last type of ventilation is in the case of an emergency, like the times the train is caught in fire. This kind of situation requires larger amounts of ventilation, which needs to be provided by mechanical means. F...
