Urban Sprawl and Smart Growth are both very familiar to those who work on urban development and planning. In a very simple way, we understand Urban Sprawl, we understand that the expansion and urbanization of the areas adjacent to the unplanned and uncontrolled areas. Most of the cities in the world have been developed and unplanned. With the development of cities in such a way that their capacity of surplus power exceeds the level of social problems, many problems arise. In the beginning of the decade of this decade, another concept of urbanization was born which is known as Smart Growth. Smart Growth is a planned, environmentally-friendly and modern urbanization. The residential areas will not be too far away from the city center, people can walk on foot, collective transport (bus, train) or cycling important places. Now it is said that new cities were planned, But what will happen to the cities that have already been built? It seems that in these old cities people have to come to different needs. There is also a certain capacity for each road. In order to protect the contact between big cities and suburbs, it exceeds the level of capacity. Mass Rapid Transit is used to address this problem in the concept of modern urbanization, bus radio transit, BRT and bus communication system, instead of fossil fuel, (Light Rail Transit, LRT) communication system. This LRT is most commonly known as Metro Rail. Bus Rapid Transit, BRT and Train (Light Rail Transit, LRT) communication system, instead of fossil fuel, live in electricity or solar power. This LRT is most commonly known as Metro Rail. Bus Rapid Transit, BRT and Train (Light Rail Transit, LRT) communication system, instead of fossil fuel, live in electricity or solar power. This LRT is most commonly known as Metro Rail.
Due to the Dhaka Metro Rail Project, the Dhaka University Campus and Social Media have become accustomed. One of the three proposed routes, the MRT-4 complained of the Air Force's allegations, and the first project is in complication. After the complexity started, some students and teachers of Dhaka University started the movement with the MRT-6 route. The students of the university could not understand what the allegations could have been. There were train stations near the one of the two universities who had the opportunity to study abroad. The train saw many complaints and huffs of the students, but due to complete reverse, express trains did not stand in that station and there were not enough trains every day. Considering the journey of students, the planning of Mass Rapid Transit is planned in the universities of the Western and Far Eastern countries. There will be many examples in the nets with a few bahataghatati.

Where can be the reason for objection to the number of students and teachers of Dhaka University, where there are arrangements for metro rail in many reputed universities of the world? On-line news portals that were found by searching the news are such that
University students say, if the metro rail goes through Dhaka University; Then the entire educational campus of the campus will be threatened. Especially damaged will be Fine Arts, TSC and Doyle Chattar area. Due to the metro rail, one of the iconic icon-building of the University of Curzon Hall has a brick.
Tangib Uddin Khan, Professor of International Relations Division, said, "The Dhaka University will be suppressed in the metro area. The country's intellectuals will be suppressed. The biggest fallout of this type of development is unwiseness. This kind of stubborn development will bring many complications to build history. '
Sociologist Sameena Lutfa said, "This project is actually a development of crap. Such a big project will be done by DU But the work of passing the University of Dhaka was started. There will be no vibration due to this railway, and in some way the research work can not be done in the science department labs. The metrole's shaky words will surprise everyone.

Taisera Tashiran, a student of the soul-rationing department of the human chain, said the educational environment of the entire campus will be threatened if the route of the metro rail is given by Dhaka University. Especially damaged will be Fine Arts, TSC and Doyle Chattar area.

A group is also promoting some pictures of social media. They appear in the metrorel peer / column Raju standing on the altar of sculpture and Viaduct is going on the TSC.
When trying to send messages with photoshop and inferred information, it should be understood that there is no objective purpose behind it. According to the description given by the Dhaka Transport Coordination Authority, the allotment of the metro rail will be along the road median. Accordingly, the picture is completely false and it is completely irrelevant considering it. There is a lot of difference between the metro rail and the general railways. Light Rail is powered by electricity and solar power, not fossil fuel, its speed and acceleration rate is much higher, by which words and environmental pollution are the lowest. It can be said that a private person has polluted more than this. So the allegation of noise pollution is also very weak. By comparing the two pictures below, it can be understood that the dirt truck is more polluting than the metro rail.

Official Metro Rail Regulation Metro Rail Corporation uses self-lubricating wheel technology in rail bends to reduce noise pollution. Suppose they use the same technology in this case.

Now let's face the problem of earthquake of Metro Rail. Vibration Mitigation at Light Rail is available in various ways and at different levels. Vibration is dealt with by the mass spacing and hydraulic arm in the elastomeric and polymer padding and sub-structure level at Super Structure Level.

Now it can be said in Bangladesh whether any such pollution prevention business will be implemented in Bangladesh. MRT-5, 4 and 6A Light Rail technology, and this technology requires the use of these prevention technologies. If this is not implemented then it should be called a general train, not light rail. If we believe in the reality of the Padma bridge, I do not see any reason to believe in the reality of sound and vibration pollution free Metro Rail. Yet all the complaints I have heard against Metro Rail still seems to be the reason for not knowing about the Mass Rapid Transit or just because of motivational motivation. Doctors of chemistry or physics should not be able to comprehend in the laboratory, because they do not have the knowledge of the social sciences. Technicians should think about the engineers, And the urban planists will do the rail alliance any way. Hopefully, this metro will be transmitted to Chep. All the prehistoric thoughts that are gathered in the education consciousness.
