Essays providing solutions to problems are normally written in a formal style, and so you should avoid using colloquial expressions, short forms or personal language. In the first paragraph we state the problem. In the main body paragraphs we write our suggestions supported by possible results. We write our suggestions in separate paragraphs. In the conclusion we summarise our suggestions.
1 Heavy traffic is one of the most serious problems that our cities have to deal with nowadays. What can we do, then, to reduce traffic in our city centres?
2 To begin with, it is important to improve public transport and to encourage people to use it to commute to work and to school. The result would be fewer cars in the city and consequently fewer traffic jams.
3 Another solution would be to encourage people to participate in car sharing programmes. This means several employees would share one car to work instead of each coming in their own car. Again, this would reduce the number of cars on the streets.
4 Finally, it would be a good idea to create more cycling lanes. If this was done, people would be encouraged to cycle instead of taking their car.
5 To sum up, there are many ways to reduce traffic in the city. Applying just some of these ideas would result in a lot less traffic in our cities.
