Despite the presence of 90% of double-fuel taxis (gasoline + CNG) in the urban taxi fleet, fuel consumption choices are more dependent on pricing policies and factors such as gasoline subsidies and quotas, and with the slightest change in fuel rates and quotas, use natural gas fuel. . Impact and challenge fuel management in the public transport fleet. The main purpose of this is to identify way...
looking at the structure of the cities, especially older parts of the city, it is seen that most of the urban public parts and elements are constructed not with any reliance on state resources and credits, but based on the consecration systems and public investments. added to the sublime religious, social and economic values latent in the consecration culture, its impact in creating identity an...
Usually, various kinds of floods are distinguished based on the origin or on the main processes. Basically, the cause of the flood can be overflow over the banks of the main channel, direct runoff or failure of a levee or other structure. Flash floods are typical of steep beds and / or high intensity rainfalls. In mountain areas, they can be associated to debris flows or highly concentrated bed...
Not long ago, city gates and entryways had high spatial value and were among the landmarks for marking city boundaries. Today with cities having been expanded and developed, such aspect of the entrance concept is lost and entryways are turned to passages for transportation. In fact, the rich spatial value of such entrances has decreased as they are solely spaces for passing through out or into ...
Necessity and importance of energy in state economic, social, and political structure and stability of and terminable fossil resources have been centerpiece of attention to energy issue in last few years. Urban railway, as one of the main pillars of urban economy, has increased the importance of this sector based on mass transit with advantages such as economic savings in fuel consumption, prev...
Currently, green rating systems are mainly utilized for correctly sizing mechanical and electrical systems, which have short lifetime expectancies. In these systems, passive solar and bio-climatic architecture, which have long lifetime expectancies, are neglected. Urban rating systems consider buildings and services in addition to neighborhoods and public transportation as integral parts of the...
This paper proposes a technique for group object motion estimation based on evolving graph networks. The main novelty over alternative group tracking techniques stems from learning the network structure for the group. An algorithm is proposed for automatic graph structure initialisation, incorporation of new nodes and unexisting nodes removal in parallel with the edge update. This evolving grap...
Aims & Backgrounds: Today, the inconsistencies range of last seven decades planning and urban plans which were due to the lack of formulating an indigenous theory base on the Iranchr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))s planning environment characteristics, are visible. Achieving to the interacted urban planning theory with the official structural elements of Iran’s planning e...
Numerous studies have illustrated how denser urban forms lead to smaller greenhouse gas (GHG) emissions from passenger transport. Many of these studies have excluded aviation since the association between urban structure and air travel is not as intuitive as it is the case of ground travel. However, several recent studies have concluded that air travel is a significant contributor to the GHGs f...
