Good morning, everyone. Today we're going to discuss the history of urban transport. In the early 20th century, most cities relied on trams, but after World War II, many countries shifted to buses and private cars. However, in the 1990s, a renewed interest in sustainable transport led to the return of trams in some European cities. For example, the city of Strasbourg introduced a modern tram system in 1994, which not only reduced traffic congestion but also became a symbol of urban renewal. Interestingly, the initial cost was high, but the long-term benefits were significant.
