Greetings!
I'll be happy to help, although I'm afraid I don't know anything about the topic. I can help with writing advice, however.
Let's start with the first paragraph:
Downtown Panama City
is involved all the areas from Tomba Muerto to Avenida Balboa. These
areas (main streets) have always been a traffic problem. - Downtown Panama City
contains streets from Tomba Muerto to Avenida Balboa. These
main streets have always been a traffic problem.
no space for
subway, sky train. - no space for
subways or sky trains.
That's all I see that needs changing in the excerpts you sent. As for advice on solutions--your research on the topic should help you find solutions that have been suggested by other people. Once you have discovered what other people think, you can agree or disagree with them and offer your own suggestions for improvement.
I wish you the best of luck with your paper!
