Using public transport
Many people who do not have cars use buses, trolleybuses, trams to go place near their house, and they use trains to places far away. Local transport is more often private. When using public transport people may need a ticket or card to be able to get on. On trams they get a ticket that they put in a machine and it tells them when their ticket runs out. On buses and trolleybuses they buy their ticket from the driver and put it into a machine, on trains they use . A timetable tells them when they come, since they can only go when and where the transport is going. Public transport is also good for the environment. When many people use the same vehicle, fewer cars are on the road. Fewer cars make less pollution. Cost is low, because it is very cheap to catch public transport every day, which is why even people who own a car often use public transport. To my mind the best way to travel along the city is to walk. When you go on foot, you do not depend on any kind of transport. You can observe the beauty of the buildings and landscapes wandering along the streets, you can go anywhere you like. These are the advantages. But, of course, the disadvantages of foot walks are the time you spent while walking.
