A tram is a vehicle that runs on tracks, such as a train or a metro. Compared to the train, the requirements that the vehicles and infrastructure must meet are lower.

This is especially common with the "city tram", which provides public transport within a municipality or conurbation. Trams (unlike other rail vehicles) are equipped with direction indicators and brake lights for street driving.
Thus, as a positive aspect, the tram adds a method of public transport to cities, which makes life easier for citizens, who do not necessarily have to depend on their private cars to move around the city. However, on the negative side, trams can cause traffic problems such as traffic jams or accidents, since they circulate on the street like other cars.
