Tram networks and urban mobility: Evidence from German cities

Source abstract

What role do tram networks play in shaping urban mobility? We study the case of West Germany, where many cities decommissioned their tram systems in the 1950s and 1960s. Using data covering 120 German cities between 1948 and 1990, we analyse how tram decommissionings affected vehicle ownership and public transport use in the long run. Difference-in-differences and event study estimations show that cities that decommissioned their trams experienced a permanent increase of at least 10% in the number of private vehicles. Decommissioning trams is also associated with fewer public transport users, even when accounting for alternatives such as bus services. This suggests that rail-based transport modes such as trams are essential to facilitating the shift towards more sustainable urban transport.
