The Platform Screen Doors improve Indoor Air Quality (IAQ) in the subway station; however, and the air quality is degraded in the subway tunnel. CO2 concentration and indoor particulate matter value are high in the tunnel. The IAQ level in subway tunnel degrades by increasing the train movements. Air-curtain installation reduces dusts, particles and moving toxic smokes and permits traffic by ge...
Recently, many studies have tried to find travel patterns to understand citizen’s movement behaviours and improve transportation services based on the big data in public transportation systems. This research introduces a method of discovering and evaluating spatial movement patterns from smart card transaction data of multi-modal transportation networks such as subway and bus. The transaction d...
Subway transportation system is a new phenomenon in Iran. Noise annoyance interferes with the individual's task performance, and the required alertness in the driving of subway trains. This is the first study conducted to measure the level of noise and noise annoyance among conductors of subway organization in Tehran, Iran. This cross sectional study was conducted among 167 randomly selected tr...
In this paper we will describe our experiences with modelling and simulating realistic railroad systems, based on component-oriented Petri Nets. Several libraries of railroad components are presented, including nets permitting the train to control the routers in the net. Petri Nets are translated into Maude in an automated way, and executed by the Maude interpreter. Since railroad models are la...
Indoor air pollution is an increasing health concern, especially in enclosed environments such as underground subway stations because of increased global usage by urban populations. This study measured the indoor air quality of underground platforms at 10 metro stations of the Taipei Rapid Transit system (TRTS) in Taiwan, including humidity, temperature, carbon monoxide (CO), carbon dioxide (CO...
We can’t preclude the possibility of the use of chemical agents by terrorists I can recall the attempt committed with Sarin in the Tokyo-subway in 1995. For that reason it is necessary to know the chemical situation in the battlefield and in our urban environment as well, for example in the subway. Actually the possible detection principles of toxic-agent-detection-devices are chemical (simple ...
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...
For sustainability and energy saving, the problem to optimize the control of heating, ventilating, and air-conditioning (HVAC) systems has attracted great attentions, but analyzing the signatures of thermal environments and HVAC systems and the evaluation of the optimization policies has encountered inefficiency and inconvenient problems due to the lack of public dataset. In this paper, we pres...
The proliferation of mobile computing has prompted navigation to be one of the most attractive and promising applications. Conventional designs of navigation systems mainly focus either indoor or outdoor navigation. However, people have a strong need for navigation from a large open indoor environment to an outdoor destination in real life. In this poster, we present a joint navigation system, ...
The travel patterns of senior citizens in Seoul were analyzed using Automatic Fare Collection (AFC) data. The focus was specifically on mode choices and transfer patterns. The results showed that 99% of trips made by senior citizens (individuals over 65 years old), who were given free subway transit passes, consisted of single-mode trips. The average travel time was 31 minutes, and subway trave...
