Metro is one of the public transportation systems that plays an effective role in transporting citizens in big cities, which is moving towards sustainable development. The quality of services provided by this system has a significant effect on the desirability and the increase of passenger engagement. In this article, the components of spatial quality affecting the satisfaction of metro users is investigated. The focus of the research has been on examining functional components. Metro line 2 of Tehran municipality is investigated as a case study of this article. In order to determine the effective components, the completion of a questionnaire among the users of Tehran Metro Line 2 stations and the use of factor analysis technique is used. Based on the results of the surveys, the parameters of metro passengers' satisfaction with escalators, arrival time, ventilation quality, interior decorations, facilities for the elderly and satisfaction with the level of lighting have the greatest impact on the satisfaction of users of Metro Line 2 stations of Tehran Municipality. In addition, sanitary services, emergency and prayer rooms are among the most popular uses of these stations. In this regard, it is suggested to work on the situation of these cases while improving the services provided to passengers in order to attract more passengers and reduce the use of private cars in urban transportation.

Obtain the desired identity and Escape from identity crisis, is Concerned with the history of humanity and human culture. Architecture and Urbanism, meet mission to cherish the cultural values in the nature of them, and accordingly an element is count identifying. The signs because of the reiterate in the daily life, reinforce an especial feeling of meaning. Concerned to the everyday increasing of the subway usage, finding a logical relationship between anatomy of a Train Station and components of its identity, has become a necessary subject. The goal of this study is make the subway regional as an import model according to the cultural signs. The subway entrances are most important places which have close relationship with the existence anatomy in the city and people. We try in the tradition and new sign for better perception of role of Semiology in identity of metro stations. In this study we try in an analysis – commentary semiology way, first approaches designed station entrance according to how to deal with symptoms are classifying. Then the agreement of each approach concerned to the environmental context and according to the three different exposure; create signs, have a sign and evasive of sign getaway be examined. Means of style " create signs " is a product sign base on context toward idealistic architecture, " have a sign ", preservation of sign and not an intelligence perception, and " evasive of sign ", is an unconsidered of cultural semiology and undesirable style of affront whit signs in design. In this regard, defined by four layers of living, Social, intellectual and spiritual context, we want to know the formation of every subway stations. In this research "spiritual context" involved mosque and spiritual center, "intellectual context" involved university, art center and museum, "social context" involved bazaar, park and plaza "living context" involved housing complex and neighborhood. The findings shows, the use of signs which reflects the culture and beliefs of citizens is a possible way which is low cost and profitable. In the reviews of every field there is the possibility of existence of every four dimensions of each text including living, social, intellectual, and spiritual context there is a sense. But what it is effective in showing the sign is the knowing of each context. With such an approach we can say, the approach of sign making is the best way of facing with sign. But we should pay attention that how much we move from living context the signs are going to be more readable. In this approach the size of using each sign is different. At every four survival context, the effective ways in identifying was not exist. (1); Understanding the context of the text, representations, or avoid symptoms, (2); understanding the text layer, and to identify the dominant source of And (3); to select the desired mode based on a textual indication of exposure. Reread the text, we can say that, exited for each entrance station for a good representation of the Iranian - Islamic.

With the increase in population of cities and progress of technology, people demand toward a comfortable life has also increased. Traffic jams in big cities and shortage of parking lots have made necessary the need for use of underground spaces more than ever. The use of underground metro trains as a fast and safe vehicle could be appropriate alternative for passengers. However, movement of trains with appropriate speed in between stations produces vibrations that may sometimes be disturbing for people living in the region. These vibrations which are one of the most serious concerns related to region close to transportation systems could cause vibration of structures and hazardous noises inside buildings. In addition to hazard to human, these vibrations could affect old buildings and equipments. They could cause fatigue in the materials of ground and structure, create differential settlement, crack in walls, resonance and other difficulties. Therefore, in designing new rail road, evaluation of vibrations due to movement of trains is one of the important parameter in selecting the route and the type of rail system. In this research the vibrations in the ground surface due to passage of metro trains in city of Ahvaz metro under construction were evaluated.
By performing dynamic analysis on each station along the metro line and also using empirical method, the vibrations due to passage of train on the surface of ground were predicted and the regions that have high vibration potential are identified. Also the effects of different parameters on these vibrations were evaluated. The results show that in general the levels of vibrations in the northeast part of the route are higher than the southwest part. One of the most important factors responsible for this observation is the shallow depth of the rock and also soil profile in the northeast part of the route. Also the results show that utilization of new methods for damping vibrations cause a considerable decrease in the level of vibrations.
