Suppose we have a very crowded city. 118.29 sq mile and population 7.001 million. Now the government made you the prime architect of the city and have to solve the extreme traffic jam problem. We cannot build subway underneath the ground because land is muddy and wet deep underneath.
There are lots of buildings and densely situated and no space inside the city to build a pillar for metro or LRT (Light Railway Transit) or no space for Maglev. There are a couple of highways and flyovers but they are jam-packed. The main transit is rickshaws, taxis, buses, cars, vans, and private cars. If you were an architect of that city how would you have solved that traffic jam problem?
Right now the city is centralized. Would you decentralize each city in each province and build independent and best hospitals, schools, colleges, universities, clinics in those cities of each province so people don't have to come to the city frequently?
The city I am talking about is Dhaka city.
Here is the map.
Do you think if you can design a crossed(North to south Tongi to Narayanganj and and east to west Gabtoli to Chanpara) LRT or Metro over Dhaka city (just somehow) that would solve the problem? And put toll on certain roads. Improve lighting systems. And inspire and motivate people to use public transportation would that help?
