i agree with urbastar, though tehran currently lacks the culture and the streets are quite dangerous, its easy to implement it in the southern half. maybe in the future small electric bicycles will also help in difficult and hilly regions of the cityBiking will never work in Tehran, too many hills, and crazy driving. It should be promoted more in cities like Yazd, Isfahan, and such.
I dont agree.
Once cities get to a certain size, everyone driving around just doesn't work. Japan has figured this out some time ago. Tokyo is the largest city in the world and has a very small proportion of journeys made by car. There is just not enough space for them in urban Japan. Many large north American, Australasian and Khaleeji cities were planned and built as very low density, car centric sprawl, so most people could drive. But they still have terrible congestion and an expensive and unsustainable road systems that push the municipalities into debt. That mid 20th century American model is failing. High density with efficient mass transit systems are the optimum for million+ conurbations.
Tehran is a high density megacity with way too many cars on the road and a municipality and national government that is reluctant to tackle urban car drivers. They are building up the public transport infrastructure, but it has been all carrot and no stick so far.
