Thessaloniki Metro extension cuts traffic 8%, travel time 13% in first month

The first month of the Kalamaria metro extension in Thessaloniki shows an 8% reduction in traffic load and a 13% reduction in travel time, indicating early operational success. The data is preliminary and based on one month of operations, so long-term impact remains uncertain. This matters as it demonstrates the potential of urban transit investments to alleviate congestion in a major Greek city.
