FLYOVERS, not enough
The best mode of public transit system is the inner city rail. Instead of flyovers the government should create train systems that arrive every 30 minutes at stations located in major sections of every city. We already have trains that connect different cities so why not a system to go from Gulshan to Banani to Dhanmondi. We already have buses that can make localised stops within the areas. The customers will need to buy tickets. The rides should be secure and clean and the payment obtained from these rides should be used to maintain this public system. Dhaka itself has 9 million people and if even half that population attempts to use the train, imagine the amount of revenue that can be generated to maintain this system.
The flyovers while great for a short-term fix will not sustain the population growth. Also, they do not generate any form of revenue for upkeep and maintenance. It is time enough for us to take a chapter out of cities such as Tokyo, New York and London which literally curbed their traffic and transportation problems greatly with inner city rail services. Why can't we?
