Hello, I want to do a research on the challenges of urbanism; I request dear researchers to raise the challenges of urbanism in their countries by mentioning the name of the country.
I live in the capital of Iran (Tehran). Key crises affecting urbanization include unbalanced and rapid population growth that causes development in the suburbs with high land consumption, inefficient urban land use, and environmental destruction with unbridled urban development. Also, in the discussion of street transportation network, the focus is on increasing the speed of cars through widening the roads, creating uneven intersections or building new roads. In this way, the movement is facilitated and it is not effective near the origin-destination. While urban planning should be done based on accessibility. One of the effective indicators is the rout factor index. For more explanation, you can refer to the two researches done in my profile if needed.
