A problem in the world’s most CBDs is that the volume of traffic caused air pollution and was a danger to health and safety of shoppers and other pedestrians. Fortunately this problem does not apply to Vienna anymore. In the past it used to be a problem in Vienna too but the government acted fast and used certain precautions to end this problem. What they did was that they placed many different types of public transport like buses, trams and trains. These encouraged people to not bring their cars out to the first district and so pollution was reduced. The government also came up with another solution and that was to increase the prices of parking in the first district. This discouraged people to use their cars in the CBD because they would have to pay a lot of money for parking. All these ideas helped and now there is almost no pollution in the CBD of Vienna.
In most CBDs increasingly taller buildings were built to try and offset the high rates and rents that resulted from the high land values. This is a big problem in a city like Chicago or New York, where all the buildings are very high and have many small apartments. This is not a big problem in Vienna though because the government does not allow people to build houses which are taller than the roof of stephansdom, and so there are no tall buildings in Vienna’s CBD. Although there aren’t many very tall buildings, the land prices are very high and that results in not many people living in the first district.
A major problem in most CBDs is that larger shops moved out and re-located on less congested sites in either old inner city area or on the rural urban fringe. This problem leads to not having many large shops in the city and also many shops will be forced to move. This is also a problem in Vienna’s CBD since many large shops and department stores like furniture and carpet shops were forced to move out of the CBD and go to other locations outside the city to the old inner city part
