19 Review public transport (buses and minibuses) to 2025 The proposed bus network in Tehran Proposed specific lines in Tehran In 2020 the share of public transport and semi public transport trips per day is 75% of the share of public transport, including urban train, bus and minibus totaling 55%of this amount 22% share of the bus and a 3% share buses and minibuses with service type 19

20 Effects of increasing Metro shares on decreasing fuel consumption Due to the increase in the share of rail transport from 8.1% to 30% in accordance with the law and the increasing frequency of 1.6 to 504 million trips in 2020 based on comprehensive plan and on the other hand considering the savings in fuel consumption of 6 liters per trip by subway, it can conclude that 3.8 million people travel by subway can lead to reduce 2.3 million liters daily consumption 20

21 Gasoline consumption per week Analysis of the relationship between fuel consumption and land use Taxi cars basically have lower age of vehicles and generally due to the lack of tuning, the fuel consumption of these vehicles is much higher than other vehicles The number of taxi vehicles are in very high Volume of levels that will have a major impact on fuel consumption and total The black line in the figure is the average fuel consumption per group and whatever the more length of confident is more so it means the distribution of consumption of the group Graph comparing the fuel consumption by 95% confident among different user groups 21

22 متوسط ميزان مصرف سوخت ( ليتر در هفته ) The effect of the fuel system on fuel consumption Although the land use has an impact on fuel consumption and also bunkering system also has no effect on fuel consumption. But Fuel system has effect on fuel consumption due to the type of land use. So that if the vehicle with usage as a taxi and with a carburetor so in this mode fuel consumption is much higher than in other cases. Therefore, the taxi cars with carburetor system have basically high fuel consumption. Confident length 95% for comparing fuel system on fuel consumption سيستم سوخت رساني 22

23 Analysis of Statistical Population of Working Vehicles The age distribution of vehicles in different areas are not same Distribution of working vehicles at different times are not equal. So maximum Working vehicles population exist before 12 and in district no. 6 and the minimum Working vehicles population exist before 12 o clock and in district no. 18. The maximum estimated Working Vehicles population with 95% Confidence is about 2,291,757, 95%. But working vehicle population is in the form of a function of scattering which varies in different area and different hours. 23

24 Synthesized strategies from the SWOT matrix method Development and enhancement of systems and modern technology Development of public transport, with emphasis on expanding the subway and express bus lines Making culture in order to use public transport on the basis of religious beliefs Upgrade the standard of vehicles by use of new technology Outdated and worn out old and high consuming vehicles Actuatingه the real fuel cost and omitting subsidy To finance the users of public transport and support low consumers Limiting system performance, including the real charges and penalties for high consumers Create Clean transport infrastructure development such as bicycle and pedestrian Development of electronic services for purchasing and administrative services and reduce traffic Rehabilitate and improve freight and cargo Network of roads and appropriate access development Proper use of the private sector to participate in development projects Focus and avoiding a multiplicity of decision-making units in traffic and transportation sector Government support in financing the development of public and clean transport Expand inspection centers to control fuel consumption 24
