Answer:
We can use the example of the Greater Accra region, one of the new regions of Ghana.
Explanation:
The Greater Accra region consists essentially of the city of Accra, and its immediate sorroundings, and has over 4 million people.
As the most populated region in the country, its regional economy is the most important for Ghana. It is where a great part of the country's industrial and service sectors are located. The reason for this is geographical: people living close to each other in cities tend to form closer economic ties that increase efficiency and productivity.
The trolleys have been reduced over the last decades, after their initial increase as a public transportation, when new and better ways were discovered/produced for transport, their decline has started.
The buses since their invention, had grown in number and became a very important part of every city's public transportation, and still are.
The rapid transit is the most recent one of the mentioned in here. It's popularity has grown, number increased, and is very practical because it is not causing traffic mess. It is very important transport asset nowadays and makes lives of millions of people much easier.
