Public transport
Traffic is a problem all around the world. Roads are full to bursting, traffic systems struggling to cope. Governments all around the world are trying to encourage the use of public transport for its environmental benefits.
But try this to get your head around the difference it could make. This is the same number of people on a bus and in individual cars. Look at the difference in space taken up on the road. That would definitely make the morning commute a lot quicker.
