the aim of the present study is to analyze the effect of city form on fuel consumption in Karaj metropolis. The data and information required for the research have been collected in two ways: library (study of documents, plans, articles, etc.) and referring to related organizations (municipality, National Petroleum Products Distribution Company, etc.). In order to analyze the data, G statistical test and the Moran model were used to determine the pattern of gasoline consumption in Karaj, and geographic weight regression (GWR) was used to determine the spatial variation between city form variables (mixing, accessibility) and gasoline consumption. The results showed that central neighborhoods of areas 5,1,7,8,9 such as; Dehghan Villas 1 and2, Hyderabad, western Golshahr 1 and 2, Movahedan town, eastern Golshahr, Mehrvila and Karmandan dormitory have the highest accessibility index, and Mehrshahr suburbs, districts 10 and 6 have the lowest accessibility index to services, administrative, commercial, educational. Also, according to the value; 462 / 10Z-Scorse = and the value of P-Value = 0, it was determined that the pattern of gasoline consumption in Karaj is clustered. Also, the value of R2 of the accessibility variable is equal to 0.88. That is, the city form index according to this variable at the 95% confidence level justifies 88% of gasoline consumption. The value of R2 of the user mixing variable is equal to 0.87. That is, according to this variable at the 95% confidence level the city form index justifies 87% of gasoline consumption.

The aim of the present research was to study environmental effects of Mashhad city transport using ecological method, and to evaluate its economical outputs on citizens. The method used in this research was ecological footprint, which determines the relation between "consumption and waste production by humans" and "resource production and waste absorption by nature".The current research is conducted based on the considering of the present situation as the basic scenario and compare it with the future situation of development and operation of other railway network lines as the ideal scenario. According to the results obtained from the first scenario (The current trend continuation), Mashhad city transport ecological footprint will rise from 0.11 ha per person in 2013 to 0.14 ha in the year of 2025. Energy consumption in transportation sector will be 54 million Gj, of which gasoline share solely is 69% among all forms of energy. Based on the ideal scenario and by completion of rail network, energy consumption will fall to 44 million Gj and ecological footprint will remain 0.11 ha per person, which in addition of having environmental positive effects, leads to gasoline consumption reduction and economic improvement. Therefore, saving resulting from gasoline consumption reduction can solely justify constructional costs of Mashhad Railway Company.
