problems

1. Find the four main causes of the high pollution index in the city of

Medellin.

2. Obtain implementations that help solve the problem and that have been

useful in other cities in the world.

3. Analyze the possible implementations obtained and choose the three with

the highest probability of success in our city.

4. Develop a program that allows the solutions to be implemented in an

integrated manner.

-

The

great increase of cars, motorcycles, buses and trucks, which generate gases

constantly. Also vehicles with more years in circulation may be more polluting.

-

The

production of gases and wastes that are not eliminated or filtered in the

correct way generated by the industry.

-

The

lack of green areas.

-

The

topography of the valley of Aburrá, since the mountains prevent that the

polluted air can ascend and be taken out of the Valley by the trade winds.

-

The

Excess of pollution is causing respiratory problems in people

-

Increasing

pollution in the city reduces the possibility of doing outdoor activities

-

The

indiscriminate felling of trees generates more pollution in the city

-

By

increasing the size of the contaminating particles, it creates eye irritation

- With increasing pollution, mortality from respiratory

diseases increased

-

Accelerate

smoothly: try to reduce the need to slow down and then accelerate by

anticipating traffic conditions in front of you.

-

Avoid

aggressive city driving. A European test showed that "jackrabbit"

starts from traffic lights and hard braking reduced travel time by only 4% (the

equivalent of 2.5 minutes out of a 60-minute trip). However, fuel consumption

increased by 37%, and some toxic emissions were more than five times higher.

-

Slow down:

excessive highway speeds add to fuel consumption over the same distance.

-

Avoid

idling for long periods. Generally idling for more than 30 seconds wastes fuel

and produces additional pollution.

-

Avoid

warming your car up for long periods. Modern car engines warm up quite quickly

even in winter weather - 30 seconds of idle operation is all that is required

before driving.
