Cities with a metro rail system have the best success at lowering car usage, according to European research. The team used a large mobility dataset to analyse how people get around different European cities and how this is influenced by whether they have a metro network, a tram network or neither. They say that compared to cities with a tram network or no rail system, cities with a metro have a lower share of car journeys. Reducing car journeys has benefits for the environment, the researchers say, while an improved public transport network also improves mobility, especially for disadvantaged communities within a city, which in turn improves equity and quality of life.
