Public transportation is a large factor in reducing air pollution. The better the public transportation system is the larger amount of people will use it.

Let's use Los Angeles and Honolulu as examples.

Los Angeles has buses that go up and down the main roads. These main roads are about 4+ blocks apart. Say Street 1, then 4 blocks street 2, then another 4 blocks street 3. IF there were buses going back and forth between those streets at intervals the buses would be used more often. As it is there is *1* bus that goes between these streets. Another negative to Los Angeles' public transportation is you pay per ride. If you get off you have to pay again.

Now take Honolulu. There's several central bus depots depending on the bus you want you can get to any of them at one of these. There are buses that circle the whole island of Oahu, no matter where you need to go on the island you can get there by bus. Honolulu's buses give you a transfer that is usually good for a couple hours, and as long as the transfer is good you can bus hop to your heart's content.

If you could get everywhere you needed to go using public transportation would you use a car? For many people the answer is yes. When a city fails to meet that criteria with their public transportation the air pollution impact of public transportation is not as great as they hope. Though there is still some positive impact because there are people who will ride the bus and forgo the car.

Is public transport good for the environment?

In general the answer is that the same trip carried out by public transport is better for the environment than the private car, however, the answer is sometimes more complicated. For instance, if someone buys a car they may change their journey completely rather than shopping in central Manchester, they may go to the Trafford Centre instead. Nearly all the car traffic growth since 1950 has been caused by long car journeys replacing short bus and walking ones. We do know from experience in Sheffield that good, cheap public transport means that many people will choose not to buy a car. We also know from London that regulated, integrated public transport really can attract people out of their cars, reduce pollution and make towns and cities a better place to live in. But good public transport is only part of the answer. Planners must only agree development at places that are easy to get to by public transport, otherwise car use and the associated environmental damage such as pollution, noise and new roads will continue to increase.
